PELICAN

Series P

Sweeper

efficiently cleans large, paved areas, such as streets and parking lots. It can be equipped with a broom on each side to increase total sweeping path. Side brooms also help to bring debris out of the gutter and onto the conveyor.

D-1

DESCRIPTION

Page 24

WHY SWEEP?

Street sweeping is an essential part of sanitation. In health, ecology and aesthetics, the community benefits from clean streets. Clean streets reduce dust and dust-borne contaminants, bacteria from decomposition of organic matter, pollutants entering stormwater systems and accidents due to debris in the roadway. Community pride is enhanced by a clean environment. People are less likely to litter in a clean area. Tourists have a positive first impression of the community, which may encourage them to stay longer and return more often.

MECHANICAL/BROOM SWEEPERS

Mechanical, or broom, sweepers remove debris by sweeping it onto a conveyor. The conveyor carries the debris to a hopper. The No-Jam™ hopper conveyor of Elgin Pelican was originally patented. This

revolutionary design sweeps debris up onto the conveyor, eliminating the problems of jamming.

PELICAN

The Pelican is the world’s most popular sweeper. This three-wheel design is flexible enough to get into tight corners and around parked cars, yet capable of picking up large objects, such as branches, hub caps and bottles. When the hopper is full, the Pelican hopper dumps straight ahead into a dump truck or onto the ground. This straight ahead approach uses only one lane, to avoid blocking traffic.

WATER SPRAY

A water spray system controls dust during sweeping. Nozzles spray water at the front edge of each side broom to moisten the dust being swept by the brooms.

DESCRIPTION

D-2

PRINCIPLES OF OPERATION

Page 25

The amount of water is adjustable through use of a knob inside the cab. A 180-gallon (681 L) water tank is standard on the Pelican P, with an optional 40-gallon (151 L) tank available.

BROOMS

Hydraulically-driven brooms sweep the debris on the street onto the conveyor. The main broom is located behind the lower edge of the conveyor and directs the debris toward the conveyor. Side brooms are available on both the right and left sides. For sweeping these are lowered and rotated to move gutter debris to the conveyor.

The pattern that the brooms produce when the sweeper is stationary is a tool to evaluate the most efficient positioning of the brooms. The brooms can be adjusted to produce the best pattern and result.

CONVEYOR

deposited on it by the main broom to the hopper. Speed is in-cab controlled for variable forward and reverse.

Pavement contact is maintained by rubber dirt shoes on the sides and rubber deflectors under the chassis.

HOPPER

Debris is collected in the 3.5 yd3(2.7 m3) volumetric capacity hopper. The forward dumping hopper allows dumping to occur using only one lane of traffic. The dumping height is variable up to 9 ft 6 in. (2895 mm).

After dumping the hopper should be washed down for maximum efficiency and long life.

CAB

Visibility is a full 360° in the cab of the Pelican P (Figure D-2). The bubble windows on each door, a

full-width windshield and rear windows allow the operator to see everything that is happening while sweeping.

GUIDE WHEEL

The rear, dual-tire, guide wheel (Figure D-5) allows superior maneuverability to get around parked cars and tight corners.

An optional sprung guide wheel increases operator comfort and decreases stress on the sweeper. The 4spring suspension absorbs shock and is especially important in areas with a number of potholes.

General Sweeping Guidelines

Page 48

While sweeping light material like leaves, if the sweeper starts pushing a pile of the material, sweeping may be improved by raising the conveyor slightly. To make this change, tap the MB / Conv Height switch (50, Figure O-1).

SWEEPING PATTERNS

Broom sweeping patterns are a guideline of sweeping performance. Patterns should be checked daily.

A pattern may be wrong because of incorrect broom downpressure, incorrect broom angle, or excessive broom wear.

A pattern narrower than that in Figure O-8 indicates that there is too little downpressure, which will result in poor sweeping performance. A pattern wider than the diagram indicates excessive downpressure, which will cause the broom to wear too fast.

If a side broom is set too flat, debris will be scattered instead of being directed to the path of the

conveyor. If a side broom is tilted at too large an angle, debris will trail or be scattered, and the broom will wear too fast. If the main broom is not kept parallel to the swept surface, the broom will wear into a coned (tapered) shape and will give poor sweeping performance.

If a broom’s bristles have worn to less than half of their original length, the broom will produce a small pattern and poor sweeping performance.

To check the broom patterns:

1. Make sure that the tires are inflated to the correct pressure.

2. Park the sweeper on a level, paved surface.

3. Using the MB / Conv Height switch (50, Figure O-1) and the Broom Height switch(es) (26 and/or 46), lower the main broom and side broom(s).

4. As necessary, use the Broom Rotate switches (22, 27, 45) to start rotation of the brooms.

5. Using the Engine Throttle Control knob (53, Figure O-2), increase engine speed to about 2500 rpm.

6. Sweep in one spot for about 15 seconds.

7. Stop broom rotation by using the Broom Rotate switches (22, 27, and/or 45, Figure O-1).

8. Use the Broom Height switch(es) (26 and/or

46) to raise the side brooms.

9. If the sweeper has standard main broom suspension, use the MB / Conv Height switch (50) to raise the main broom. If the sweeper has hydraulic main broom suspension, use the CONV LOWER / MB/CONV UP switch (47) to raise the main broom.

10. Drive forward far enough to reveal the patterns left on the pavement by the brooms.

11. Check that the side broom patterns are crescent-shaped and approximately 4 inches wide

O-17

OPERATION

Page 50

at the top. The patterns should overlap the path of the main broom (Figure O-8).

12. Check that the main broom pattern is of an even width along its whole length (does not taper). The pattern should be 4 to 6 inches (10 to 15 cm) wide. After sweeping, the broom bristle tips should have an even amount of dirt on all of them.

If the patterns do not conform to those in Figure O8, adjust or replace the brooms, as necessary, by the procedures in the Service Procedures section.

While checking the broom patterns, also check the dirt shoe (Figure O-9) on each side of the main broom. The dirt shoe housings should be flush with the main broom. The shoes should be level with the ground.

Procedures for adjusting the shoes are in the Service Procedures Section.

REVERSING THE CONVEYOR

The conveyor may be reversed, if necessary, for example, during washdown or if an object is jammed in the conveyor.

OPERATION

O-18

Dirt Shoe

Figure O-9

Page 51

NOTICE

clearance of 3 ft (1 m). Do not raise hopper while under trees, bridges, etc.

CAUTION

Overloading the hopper can cause personal injury or damage to the sweeper. Dump the hopper frequently when loading heavy materials.

1. Come to a complete stop on level surface.

2. Stop rotation of conveyor by using Conveyor Rotate switch (49, Figure O-1).

3. As necessary, stop rotation of broom(s) by using Broom Rotate switches (22, 27, 45).

4. Raise side broom(s) by using Broom Height switches (26 and/or 46).

5. If sweeper has standard main broom suspension, use MB / Conv Height switch (50) to raise main broom and conveyor. If sweeper has hydraulic main broom suspen-

SHUTTING DOWN THE UNIT

1. Park the sweeper.

2. Use the Engine Throttle Control (53, Figure O-2) to set engine speed to idle (about 1000 RPM).

3. Set the parking brake.

4. Stop rotation of the conveyor by using the Conveyor Rotate switch (49, Figure O-1).

5. As necessary, stop rotation of the brooms by using the Broom Rotate switches (22, 27, 45).

6. Raise the side broom(s) by using the Broom Height switches (26 and/or 46).

7. If the sweeper has standard main broom suspension, use the MB / Conv Height switch (50) to raise the main broom and conveyor. If the sweeper has hydraulic main broom suspension, use the CONV LOWER / MB/CONV

UP switch (47) to raise the main broom and conveyor.

NOTICE

Before shutdown, the engine must be run at idle speed (about 1000 RPM) for at least 2 minutes to cool hot engine parts. Idling time lets the oil and coolant cool the turbocharger, cylinders, bearings, etc.

8. After the engine has idled long enough, use the Ignition switch (23) to shut down the engine. The length of time needed to cool the hot engine parts depends on the air temperature and the temperature of the engine when the sweeper was parked.

AT END OF SHIFT

For continued high performance, the sweeper must be thoroughly washed down at the end of each shift by the procedure in the Maintenance section.

O-21

OPERATION

Page 54

After washdown is complete, maintenance must be performed as directed in the Maintenance and Service Procedures sections.

Filling the fuel tank at the end of the shift will force most of the air out of the tank. This action will minimize the water condensation that can happen in the air space as the tank cools.

FUEL SYSTEM

The fuel lift pump (C, Figure SP-3) draws fuel from the fuel tank (K) and pushes it through the fuel filters (G) to the injection pump (A). The injection pump forces fuel through the injectors (E), which atomize the fuel and spray it into the combustion chamber of each cylinder. The low pressure leakoff return line (H) from the injection pump passes through each injector and returns to the fuel tank.

DRAINING FUEL WATER SEPARATOR

The water separator on the bottom of the fuel filter (Figure SP-4) should be checked daily and drained when needed. Frequency of draining will be determined by operating conditions and quality of the fuel.

To drain the separator, use the following procedure.

HYDRAULIC SYSTEM

The hydraulic system of the Pelican P is spline shaft driven. There are no belts to break or pulleys to adjust.

There are three basic hydraulic systems:

hydrostatic drive system hydraulic sweep system hydraulic steering system.

All three systems share a common hydraulic oil tank with two filters (Figure SP-5). The tank is

located next to the engine on the right hand side of the sweeper. With the hopper down, check the oil level at the sight gauge on the side of the tank.

Hydraulic Tank And Filters

Figure SP-5

Page 75

NOTICE

Elgin Sweeper Company recommends Shell Tellus T 68 or equivalent hydraulic oil. Never mix different kinds of hydraulic oil.

Use new, clean hydraulic oil that meets all Elgin Sweeper Company requirements. Never mix different types of oil. When adding oil, remove the plug on the top of the return filter and add oil. This will prefilter the oil added to the tank.

Every 500 hours of operation, drain the tank, put in new hydraulic oil, and replace the hydraulic filter elements with new elements. (Never try to clean an element for further use.) Every 1000 hours, replace the hydraulic tank breather with a new one.

SPRAY WATER SYSTEM

Spray water is used during sweeping to suppress dust and to moisten the debris for better settling in the hopper.

A fill hose is stored in the front fender (Figure SP-6). Before filling the water tank(s), always allow the hydrant to run to flush out any sediment or debris in the hydrant.

Water for the spray water system passes through a 100 mesh filter prior to entering the water pump.This stainless steel strainer filter is located under the removable left hand side panel. A shutoff

MAIN BROOM ADJUSTMENT

Standard (Chain) Suspension

To adjust the main broom contact area with a chain suspension (Figure SP-11), take the following steps.

1. Lower the main broom on a flat, level surface.

2. Adjust the spring tension on one side as necessary using the chain. For example, if the left side shows more wear (or taper) than the right side, shorten the chain on the left side to raise the left side of the broom.

Hydraulic Suspension

In the optional hydraulic main broom suspension (Figure SP-12), the snubbing spring is compressed or released to adjust for even broom wear. The factory adjustment for the left side is approximately

3.75 in, for the right 1.25 in. This counterbalances

the added weight of the drive motor on the right side.

If the left side shows more wear than the right side, raise the left side.

To adjust the main broom contact area with the optional hydraulic suspension, use the following procedure:

1. Lower the main broom on a flat, level surface.

2. Loosen the jam nut.

3. Turn the adjusting nut up or down as needed. If the adjusting nut does not want to turn, a little oil on the nut and collar will help. Two complete turns of the adjusting nut will result in about 1” of change in the taper (the difference in diameter between the ends of the broom).

4. Tighten the jam nut.

DIRT SHOE ADJUSTMENT

Dirt shoes ride perpendicular to the ground to act as a guide to keep debris between the main broom and the conveyor.

The main broom rotates between the two dirt shoes. Wings at the rear of each dirt shoe assure that the bristles are turned in and ride flush within the dirt shoe housings.

Both dirt shoes (Figure SP-13) should be correctly aligned and ride level with the surface of the road. If they are not correctly positioned, this should be corrected immediately.

To check for proper dirt shoe adjustment, use the following procedure.

1. Lower the main broom.

2. Start main broom rotation.

5. Raise the broom and drive forward to allow

components to attain transport position. In

raised transport position the dirt shoes should be parallel to, but not touching the ground.

If the dirt shoes are not level in the raised position, adjust them by loosening the two nuts holding the dirt shoe adjusting plate.

To raise the rear of the dirt shoes, lift the plate toward the lifting rod. To lower the rear of the dirt shoes, move the plate away from the lifting rod.

DIRT DEFLECTORS

Dirt deflectors are located in various places in the Pelican. They aid in keeping debris moving toward the hopper.

Dirt deflectors are installed between the conveyor and the chassis to prevent debris from spilling over the sides of the conveyor.

Two rubber deflectors span the width of the Pelican between the drive wheels. These can be removed, if necessary, during leaf removal season.

ADJUSTING CONVEYOR

Conveyor Belt Adjustments

Before belt adjustment, the conveyor belt must be clean and the lower roll area must be flushed out. The main broom and conveyor must be lowered.

NOTICE

Do not attempt to adjust the conveyor belt with the conveyor system in the raised position.

Proper conveyor belt adjustment involves first setting tension and then adjusting alignment by the procedures under Belt Tension and Belt Alignment.

NOTICE

Belt tension and alignment for both rolls are interrelated. During tension adjustment, the belt must be kept nearly centered, but tension must be correct before final adjustment of alignment. It is important to make small adjustments and to check belt tension and alignment by operating the belt for at least 30 minutes between adjustments.

A properly tensioned belt will have good clearance between each belt cleat and the lower conveyor backing plate. Too much slack will cause "flapping" of the belt against the backing plate and result in damage to the belt.

The conveyor belt must be accurately aligned, or trained, to stay on the middle of the rollers. A misaligned belt can travel across the rollers and into

the conveyor sides, where it will suffer tearing or other damage.

BELT TENSION

The conveyor belt has correct tension when there is clearance between the tip of any cleat and conveyor backing plate. If too loose, the belt may slip on the upper roll and the cleats may show wear from dragging over the backing plate. DO NOT overtighten belt, as this will cause premature failure. To adjust belt tension, use the following procedure.

WARNING

DO NOT work under or around a raised hopper.

1. After following the procedure under Conveyor Access, lower the main broom, conveyor, and side broom.

WARNING

Contact with moving parts can cause severe injury. Do not attempt repairs or go under-

neath machine with engine running. Use extreme care when making checks or adjustments that require the engine to be running.

NOTICE

All belt tension adjustments should be made with no more than one-half turn of the adjusting nuts at any one time. The conveyor should then be run at least 30 minutes to check the results before making another adjustment.

2. Loosen the jam nuts on each side of the upper conveyor assembly (Figure SP-17).

3. As needed to achieve correct tension that is uniform across the belt, turn both adjusting nuts. Turn the nuts clockwise to increase tension or counterclockwise to decrease tension. Turn each nut only one-half turn at a time.

4. With the engine running at about 1200 RPM, operate the conveyor for at least 30 minutes between adjustments to check belt tension, alignment, and direction of travel, if any, over both the upper and lower rolls.

SERVICE

PROCEDURES

Page 86

5. If the belt "flaps" against the lower conveyor cover, increase overall belt tension by continuing adjustment steps on both sides of the upper conveyor roll.

6. If alignment does not need adjusting, tighten the jam nuts.

BELT ALIGNMENT

Proper belt alignment will require making small adjustments to the upper roll as outlined below. As a result, upper conveyor roll take-ups may not have equal final adjustments.

In some cases, adjusting the upper roll may not be sufficient to keep the belt centered on both rolls. It may be necessary to make similar adjustments to the lower roll.

Reference to right or left side of the sweeper is relative to the operator's position in the driver's seat.

WARNING

DO NOT work under or around a raised hopper.

Before beginning belt alignment, follow the procedure under Conveyor Access.

Follow these guidelines for correct belt alignment:

Adjust the conveyor to give correct belt tension before making final adjustments in alignment.

Operate the conveyor long enough to bring the belt up to steady operating temperature, before trying to completely adjust alignment.

............................BELT TRAVELS TO THE RIGHT

Increasing tension on the right side or decreasing tension on the left will draw the belt to the left.

BELT TRAVELS TO THE LEFT.............................

Increasing tension on the left side or decreasing tension on the right will draw the belt to the right.

Operate the conveyor for at least 30 minutes between adjustments.

NOTICE

Do not operate conveyor in reverse for more than 30

seconds without allowing forward motion to center belt. Excessive reverse running can damage belt.

When the belt seems to be properly centered, test the stability of the alignment by operating the conveyor in reverse for about 15 seconds and then running it forward. Within about 5 minutes, a correctly adjusted conveyor will center the belt and keep it centered.

The conveyor structure should be checked and adjusted for squareness in the sweeper and to the sweeping surface. Use the following procedure.

1. On the conveyor structure, select a reference point (e.g., a bolt or bracket) that is common to both sides.

2. Measure the distance from each reference point to the surface on which the sweeper is standing.

3. If the two measurements do not closely match, square the conveyor structure by taking the following steps.

a. Raise the conveyor.

b. Block and support the conveyor.

c. With the pistons of the conveyor lift cylin-

ders (Figure SP-20) retracted, remove the snap ring at the bottom of the appropriate cylinder, and remove the cylinder.

d. Add one or more shim washers at the rod

end of the cylinder.

e. Install the cylinder and snap ring.

f. Unblock and lower the conveyor.

g. Repeat the measurement procedure and, if

necessary, repeat the adjustment procedure until the conveyor structure is squared.

NOTICE

To achieve squareness, the number of washers on the two cylinders will generally be different. When ground clearance is adjusted, this difference should be maintained throughout the adjustment. See CONVEYOR GROUND CLEARANCE.

SERVICE

PROCEDURES

SP-26

Page 93

Structure Stop Bolt Adjustment

Above the conveyor lift cylinders, there are two stop bolts (Figure SP-20) that guide the conveyor in tow through U-turns and sweeping, preventing damage to the conveyor and other components under the sweeper. There should be a 1/8-inch (3 mm) gap between these bolts and the sweeper side plates. The bolts should not ride against the side plates.

Lower Roll Offset Adjustment

Lower roll offset is needed to compensate belt tension for the material "loading" effect that occurs on the right side of the conveyor during standard right-hand sweeping.

The offset is adjusted at the factory and normally needs little or no readjustment, but it should be checked with every new belt installation. Offset may be out of adjustment for a machine in the field

due to wear and loosening of the lower roll bearings and conveyor lift cylinders. Adjusting the offset can make conveyor belt installation easier or help solve alignment ("training") difficulties. See CONVEYOR BELT ADJUSTMENT.

NOTICE

Reference to right- or left-hand in the following procedure is based on the operator's seated position facing forward in the sweeper.

1. With the belt removed or belt tension released, check the left-hand lower roll bearing (Figure SP-22). The lower edge of the bearing casting should be flush with the end of the conveyor weldment. If necessary, adjust the position of the bearing.

2. Check the right-hand lower roll bearing (Figure SP-23). The lower edge of the bearing casting should be approximately one-half inch (13 mm) up from the end of the conveyor weldment.

Belt Splice Installation

Figure SP-24

Page 96

A torn or damaged belt may be repaired in the field by cutting out the damaged part with a squared cut across the whole width of the belt and inserting a new section also squared off to match the length of the part removed (Figure SP-25). This requires two splices, one at each end of the new belt section added. Should damage occur near the original splice, the new section may be added at the end and only one splice need be added.

REVERSING CONVEYOR

The conveyor assembly and belt adjustments are designed to train the belt in forward (sweeping)

motion only. The reversing feature is only for the purpose of relieving any condition which has caused a jamming effect of the belt or driving mechanism and normally will not be prolonged over a period of 30 seconds. Longer periods of time may cause the belt to run either to the extreme right or left, causing damage to the belt.

NOTICE

Do not operate conveyor in reverse for more than 30

seconds without allowing forward motion to center belt. Excessive reverse running can damage conveyor belt.
