Signal Words:

This manual uses SIGNAL WORDS to indicate the likelihood of personal injuries, as well as the probable seriousness of those injuries, if the product is misused in the ways described. Other signal words call attention to uses of the product likely cause property damage. The signal words used appear below along with the meaning of each word:

Identifies a hazardous situation which, if not avoided, WILL result in DEATH or SERIOUS INJURY. Use of this signal word is limited to the most extreme situations.

Identifies a hazardous situation which, if not avoided, COULD result in DEATH or SERIOUS INJURY.

Indicates a hazardous situation which, if not avoided, COULD result in MINOR or MODERATE injury

Identifies practices likely to result in product/property damage, such as operation that might damage the product.

Safe Use Recommendations:

We strive to identify all hazards associated with the use of our products. However, material handling is dangerous and no manual can address every risk. Ultimately, the most effective way to avoid injury is to exercise sound judgment whenever using this product.

Improper or careless operation of this drum dumper might result in serious personal injuries.

 Failure to read and understand the entire manual before assembling, using or servicing the product constitutes misuse. Read the manual whenever necessary to refresh your understanding of proper use and

maintenance procedures.  ONLY use the dumper as a means for mechanically emptying drum. ALWAYS properly load the dumper according to the directions on p. 11.  DO NOT use a damaged dumper. Examples of structural damage include: broken container restraining tube, broken fork pockets, and holes caused by rust or corrosion. Inspect the dumper before each use according to the inspection instructions on p. 11-12. DO NOT use the HBD unless it passes every element of the inspection, or until authorized maintenance personnel approve the dumper for service.

 Inspect the unit before each use according to the inspection instructions on p. 11-12.  DO NOT stand beneath or travel under the dumper chute while it is elevated.  DO NOT use this dumper UNLESS every label shown in the “Labeling diagram” on p. 24 is in place, undamaged,

and easily readable.  DO NOT exceed the capacity of the dumper. The capacity of each model appears in the tables on pp. 2-3 as well as on label 287 (see “Labeling diagram” on p. 24). The weight of the container to be dumped plus the weight of its contents must not exceed the capacity.  DO NOT modify the dumper in any way UNLESS you first obtain written approval from Vestil. Modifying the dumper without first receiving approval automatically voids the limited warranty and might make the dumper unsafe to use.

DO NOT fill the hydraulic system with brake fluid or jack oils. Only fill the hydraulic system with

either anti-wear hydraulic oil, viscosity grade 150 SUS at 100°F (ISO 32cSt at 40°C) or Dexron transmission fluid.

Installation instructions (stationary units):

Step 1: Position the dumper where

desired with a forklift.

/4” anchor bolt

Step 2: Drill holes approximately 4in.

(10cm) deep.

Step 3: Secure the dumper to the floor by

inserting the bolt holes in the base frame.

/4” anchor bolts through

Step 4: Shim and/or grout the sides of the

frame as necessary to achieve levelness.

Step 5: (AC powered units) Connect the

power cord to the power supply.

/4” anchor bolt

Shim and/or grout under the frame to level the dumper

Loading the dumper:

1. Use only properly sized waste containers: HDD-series dumpers are designed to accept 33 gallon and 55 gallon steel, plastic, and fiber drums.

2. Load the drum onto the chute: Place the drum on the base plate of the chute. The drum should rest against the back of the chute.

3. Apply the drum retainers (see diagrams in “Inspections” below): to prevent the drum from sliding out of the chute, move the retainers up or down the rails as necessary and into solid contact with the top of the drum. To move the retainers, press the rail clamps down. The hook at the end of each retainer must contact the inside wall of the drum.

4. Dump the drum: press the white (raise) button on the pendant controller to raise the chute to the dumping position. In response to the input from the controller, the piston extends and raises the bottom end of the chute. The piston extends only while the operator presses the white button. When the button is released, the cylinder stops extending and the chute stops moving. The chute maintains whatever position it is in when the button is released.

NOTE: If the net weight of the drum and its contents exceeds the capacity of the dumper, a relief valve in the hydraulic system will open. While the relief valve is open, the piston cannot extend. Consequently, the chute will not move.

5. Return the chute to the loading position: press the black (lower) button on the controller to retract the piston. As the piston retracts, it pulls the bottom end of the chute towards the ground. If the DOWN button is released before the chute is completely lowered, the chute will maintain its position.

Inspections: (Refer to FIGS. 1-8, p. 5-10)

Before each use, inspect the listed components:

1. Modular power unit, pendant controller, and wiring: examine all wires for frays, cuts, tears, etc. (DC-powered units) Check battery charge status. Cycle the chute all the way up and all the way down. Recharge the battery, if necessary.

2. Hydraulic system: check the reservoir and all hoses for pinches, kinks, punctures, and leaks.

3. Drum retainers and clamp rails: examine the retainers for damage including bends, cracks, and looseness. Each clamp should maintain position along the rail (i.e. should not slide).

4. Frame: check the hinge blocks, pivot shafts, cylinder brackets (at each end of cylinder at attachment points to the frame and the chute), legs, vertical frame, and chute for cracks, damaged welds, severe wear, and corrosion.

5. Cylinder and limit switches: verify normal function. Cycle the chute through a complete dumping sequence (fully rotated and back to the ground).When the chute reaches dumping height, the power unit should stop running. The piston should extend and retract smoothly without binding or jerking. Listen for unusual sounds that might indicate binding or grinding during operation and watch for unusual movement. If you observe any unusual sound or movement, do not use the

dumper until it has been restored to normal operating condition.

At least once per month, inspect the dumper as follows:

1. Oil level: remove the cover from the modular power unit. Then, fully raise the chute (to the 45° “dumping position”)

and observe the level of oil in the reservoir. The surface of the oil should be 1 to 1½ inches below the fill hole. If oil is needed, add oil as specified below in “Oil specifications”.

2. Pivot points: check the dumper for excessive wear. Pay particular attention to pivot points between hydraulic

cylinders and cylinder brackets, and between pivot shafts and hinge blocks.

3. Floor connection points: anchor bolts should prevent the frame from lifting off of the ground during chute

operation. Concrete around each anchor bolt should be intact, i.e. not cracked or chipped.

4. Fasteners: check each fastener connection (nuts, bolts, pins, etc.). Tighten loose connections. Replace all

damaged hardware.

5. Hydraulic hoses and electrical wires: check each wire and hose for damage (frays, kinks etc.).

6. Labels: labels should be easily readable, undamaged, and be affixed to the dumper as shown in the “Labeling

diagram” on p. 23.

Oil specifications: At least once per year change the hydraulic oil. Change the oil as soon as it becomes gritty or looks milky (indicating that water is present). With the chute in the fully lowered position, drain the oil and replace it with either Dexron transmission fluid or anti-wear hydraulic oil viscosity grade 150 SUS at 100°F (ISO 32 cSt at 40°C.

Power unit operation

The drum dumper is powered by an electric motor directly coupled to a gear pump. The pump pressurizes the hydraulic fluid. Fluid pressure causes the piston of the hydraulic cylinder to extend. Piston extension causes the bottom of the chute to rotate until it is elevated above the top of the chute. A hydraulic manifold bolted directly onto the gear pump houses the hydraulic control components. Each component is rated for 3,000psi working pressure.

Important components of the power unit include:  Electric motor: the motor is either AC powered (wall socket) or DC powered (battery). AC-powered motors can be

wired for either single-phase or three-phase operation. Regardless of phase configuration, every motor is dual-

voltage capable.  Gear pump: the pump shaft is directly coupled to the shaft of the electric motor. Several displacements are

available to match the horsepower of the motor selected.  Check valve: prevents backflow of fluid through the pump and to the reservoir. Because fluid can only flow in

response to an electrical signal from the pendant controller, the chute can maintain any position between the

raised and lowered configurations.

 Pressure relief valve: opens a path for fluid to flow back to the reservoir if fluid pressure exceeds 3,000psi.  Lowering solenoid valve: electrically-operated cartridge valve with an integral screen to keep contaminants from

entering the valve.  Pressure compensated flow control spool: this feature regulates the flow of hydraulic oil from the cylinder back to

the reservoir. It is located beneath the lowering valve. This component allows the table to lower at a

predetermined constant rate regardless of the weight of the dumper and contents. Several sizes are available.  Displacement style hydraulic cylinder: each cylinder includes a bleeder valve located at top end for removing air

from the hydraulic system.  Velocity fuse: a safety device installed in the hose port of each cylinder. If a hose is punctured while the unit is

operating, the velocity fuse closes automatically. The chute remains stationary until pressure is reapplied to the

system.  Hydraulic fluid: HO150 hydraulic fluid. To replenish the fluid, add anti-wear hydraulic fluid with a viscosity grade

of 150 SUS at 100°F (ISO 32 @ 40°C) like AW-32 or Dexron transmission fluid.

Sequence of operation:

To raise/tilt the chute, press the white (UP) button. In response, the motor turns and rotates the gear pump. As the pump rotates, oil is drawn from the reservoir, passes through the suction filter, and enters the pump.

 The gear pump propels oil through the check valve to the lift cylinder.  Releasing the white button during operation immediately halts chute movement. Additionally, an electrical upper

travel limit switch automatically turns off the motor when the chute reaches a 45° angle to the ground (horizontal).

To lower the chute, press the black (DOWN) button.  Lowering valve opens which bypasses the check valve and allows oil in the cylinder to flow to the reservoir

(through return hoses). Oil flow to the reservoir is regulated by the pressure compensated flow control valve. By regulating the volume of oil that can flow through the spool, the speed at which the chute lowers is kept constant.

 Releasing the DOWN button during operation causes all chute movement to stop. The chute will remain in the

same position until you press either button on the pendant controller.

03/10/03 9/7/2017 HDD, MANUAL

Cleaning lowering solenoid valve: If the chute slowly loses elevation without pressing the DOWN button, lower the chute completely. Then, remove, inspect, and clean the lowering cartridge valve in the following manner:

1. Lower the chute completely and turn off electrical power to the unit. If your dumper is AC powered, unplug the electrical cord from the wall socket. If your unit is DC (battery) powered, turn the power switch to the OFF position.

2. Unload the dumper.

3. Remove the nut that fastens the solenoid coil to the valve stem; then remove the coil and unscrew the valve from the manifold.

4. Inspect the valve for blockage.

5. Inspect O-rings and back-up washers for cuts, tears, etc.

6. Submerge the valve in mineral spirits or kerosene.

7. Use a thin tool, such as a small screwdriver or a hex wrench, to push the poppet in and out several times from the bottom end of the valve. The valve should move freely, about 1/16” between the closed and open positions. If the poppet sticks, the valve stem might be bent. Replace the poppet if it doesn’t free up after cleaning.

8. Remove mineral oil from the valve with compressed air.

9. Move the poppet in and out.

10. Inspect the bottom of the valve cavity in the manifold for foreign matter.

11. With the thin tool, press the middle of the flow control spool, which is located in the bottom of the cavity. It should move down and up smoothly.

12. Reinstall the valve in the manifold and tighten it to 20 lb·ft of torque.

Bleeding air from hydraulic system: If the chute lowers extremely slowly or does not lower, air in the cylinders might be the culprit. Air in the hydraulic system causes the velocity fuse to close, which traps oil in the cylinder. To overcome this problem, air must be “bled” from the system.

 Completely lower the chute and unload it;  Locate the bleeder valve located at the top of the cylinder (it looks like a grease zerk). Hold a rag over the valve

and open it about a half turn with a 1/4” or 5/16” wrench. Oil and air will sputter from the valve. Jog the motor by

pressing the white (UP) button for just a second. If air continues to escape from the bleeder valve, jog the motor

several more times. Wait at least 5 seconds between successive jogs.  Close the valve once air no longer is heard or seen bubbling out of the valve. At this point, just a clear stream of

oil is seen flowing from the bleeder valve. Close the valve.  Remove the cover from the modular power unit and check the oil level in the reservoir. If the surface of the oil is

lower than 1 to 1½ in. below the fill hole, then add oil until it is between 1 and 1½ inches of the fill hole. Add only

anti-wear hydraulic fluid with a viscosity grade of 150 SUS at 100°F (ISO 32 @ 40°C) like AW-32 or Dexron

transmission fluid.
