Hazards of Improper Use

Vestil diligently strives to identify foreseeable hazards associated with the use of its products. However, material handling is inherently dangerous and no manual can address every conceivable risk. The end-user ultimately is responsible for exercising sound judgment at all times.

If this product is used improperly or carelessly, personal injuries might result.



DO NOT modify the product in any way UNLESS you first obtain written approval from Vestil. Unauthorized

modifications automatically void the Limited Warranty and might make the product unsafe to use.

 Read the manual whenever necessary to refresh your understanding of proper use and maintenance procedures.  DO NOT exceed the capacity of the unit (see Label 287 in “Labeling diagram” on p. 17).  DO NOT stand, or sit, on the turntable or the load at any time.  Install the machine ONLY on even, level surfaces where it will not be exposed to the outdoor environment.  Keep hands, clothing, etc. out of contact with all moving parts of the machine during operation.  During operation, stand with the mast between yourself and the turntable.  DO NOT activate the turntable UNLESS the load is centered on it and stable.

Introduction

Vestil's Medium Duty Powered Stretch Wrap Machines offer the same great features as our standard duty machines in a 5,000-lb capacity unit. Complete with a powered turntable and counter-balanced stretch film mast. To operate, depress the foot pedal and manually move the mast up and down. The film-wrap tension is controlled with an adjustable, friction-brake assembly. Film placement is controlled manually by moving the carriage assembly up and down on the vertical mast. A hand operated carriage-brake allows the carriage to move freely making film application fast and simple. The system will accept 10” to 20” material. The unit ships with the mast disconnected, simply raise the mast and clamp into place. The standard manual film wrap delivery can be upgraded to 120 volt; 1-phase AC powered mast option, PMO. The hand held control is used to raise/lower the film while the foot control is used to operate the turntable. Please contact factory for Approach Ramp options on these models.

Installation

Review this entire instruction set before installing the stretch-wrap machine. Consult the manufacturer in the event

there are any questions or problems at the time of installation, or for information regarding optional features not covered by the owner’s manual. The model SWA-48 stretch-wrap machine must be removed from the shipping wood

and securely anchored to the floor before use!

• Modifications or the addition of ancillary equipment to any part of the stretch-wrap machine without prior

manufacturer’s authorization may void the machine’s warranty.

• The installation should be made so that it complies with all regulations applicable to the machine and its location.

The end-user must verify that the supplied equipment is installed so it will be suited to the environment in which it will be used.

• Installation must be performed by suitably trained personnel with access to the appropriate equipment. The

electrical aspects of the installation should be performed by an electrician.

• Choose a location for the machine that will be free of obstructions to the largest diameter load that could be placed

on the turntable. Consideration should also be given to the approach path(s) of pallet trucks and fork trucks so that personnel, the motor speed control, and the foot switch and its cord can be adequately protected from injury or damage.

For a typical installation, you will need the following:

1. A fork truck or hoisting means to unload the machine from the freight truck and to set it into place.

2. A smooth, level, and adequately strong concrete surface on which to mount the machine’s frame.

3. Concrete anchors, a masonry drill, a masonry bit, hand tools, grout, and steel shims. Consult the building’s architect or facility engineer to determine the best size and type of hardware with which to anchor the machine to the floor.

4. A power supply circuit and disconnect matching the motor voltage and current requirements. Refer to the machine’s data plate, to the labels on the control enclosure, and to the electrical section in this manual, for more information. The end-user is responsible for supplying the branch circuit’s required (by code) overcurrent and short circuit protection.

Note: Static electricity is produced on the stretch-wrap film as it pulls off the roll during the stretch-wrapping of a palletized load. The static effect might intensify in dry air. If undesirable effects of static on personnel or product are experienced, consult an ESD (electrostatic discharge) product supplier for available methods to dissipate static.

Machine Installation:

SWA-48, MANUAL

1. Move the machine to its installation location by inserting the forks of a fork lift along each side of the frame until the fork’s tips are under the ½” x 3” x 3” tabs on each side. Use care to avoid damaging the electrical components and cable.

2. Prop up the motor end of the frame on a wooden 4 x 4 (or similar).

3. Stand the stretch-wrap mast upright on the end of the machine’s frame so that the material carriage arm projects over the side of the frame. Align the hole in each corner of the mast mounting plate with its corresponding hole in the machine’s frame.

4. Bolt the stretch-wrap mast to the machine’s frame with the hardware provided, and wrench-tighten.

5. Remove the counterbalance retaining screw located approximately 12” up from the mast’s base plate, and cut the cable tie holding the mast cable to the pulley at the top of the mast.

6. Anchor the machine’s frame to the floor through the 9/16” holes located at the frame corners and at the end of the frame, under the edge of the turntable. Tighten the anchors only to the point where the frame is level.

7. Shim and/or grout under the frame sides as necessary to prevent bowing of the frame.

8. Tighten all of the floor anchors wrench-tight.

9. Bolt the motor/drive assembly onto the gear reducer using the included hardware and shaft key. When finished, the electronic drive should be facing outward over the side of the machine’s frame.

10. Insert the turntable’s power cord plug into a standard 15A or 20A, 120 VAC receptacles. If a powered mast is installed onto the machine, the turntable’s power cord can plug into the pigtail coming out of the mast’s control enclosure, and the mast’s power cord can then be plugged into a 120V receptacle to supply both parts of the machine.

11. Verify that the turntable rotates and that the speed control knob provides full speed range adjustment.

12. If a powered mast is installed, verify that the mast operates and that the mast's upper and lower travel limit switches function properly.

13. Clean up debris, and verify that all labels are intact (see “Labeling diagram” on p. 10).

Stretch Wrap Holder Assembly

The wrap holder accommodates 10-20 inch rolls of stretch wrap. Loading stretch wrap:

1. Unwind the wing nut (A) sufficiently to remove the lock spacer (6) underneath the bottom retainer (2).

2. Remove the lock spacer.

3. Remove the retainer (5) and bearing (4).

4. Remove the spent roll of stretch wrap and install a new roll.

5. Reinstall the retainer (5); secure it in place with the lock spacer (6).

6. Tighten the wing nut (A) until the roll is snugly grasped between the tube retainers (2) and (3). Adjust the tightness of the wing nut to achieve the desired degree of material stretch—the material will stretch more the more tightly the roll is grasped.

Belt Tensioning Procedure:

Numbers in the diagram to the left correspond to the procedure numbers below.

1. Loosen all 4 bolts which hold the gear reducer to its mounting bracket.

2. Loosen the mounting bolts and slide the bracket to the left.

3. Retighten the bolts loosened in step 1.

4. Loosen the jam nuts.

5. Turn the screws clockwise to increase belt tension (CCW to reduce tension).



Operation

6. Retighten the jams nuts (4) and mounting bolts (2).

Ensure that all employees involved in the operation and care of this machine understand and follow these instructions.

The standard model SWA-48 is suitable for moderate-duty, intermittent cycling with a 4,000 pound load. It is intended to be used indoors in industrial and commercial locations to apply stretch-wrap material at between three and twelve revolutions per minute (RPM) in a clockwise rotation around palletized, stable, non-hazardous loads. The maximum diameter (or diagonal, measured corner-to-corner) load size for the SWA-48 is 76”, the maximum load height is 78”. Always ensure that the load is centered on the turntable.

The material mast can utilize stretch-wrap material rolls in lengths from 10” to 20” — spacer tubes stored on the material rod allow for the use of several material roll lengths below 20”. The SWA will generally be capable of achieving stretchwrap material stretch rates of 150-200%.

Loading:

 Verify that no part of the load is overhanging below the turntable. A damaged skid with a

dragging board or an overhanging load that sags below the turntable can cause the entire load to shift suddenly if it catches on the frame.

 Do not exceed the machine’s load ratings. Damage or premature failure to the drive system or its

components could result from exceeding the listed capacity. Place loads onto the turntable slowly and gently using a pallet truck or walk-behind fork lift, using an optional approach ramp, or with a fork truck.

 Do not drop loads onto the turntable. Even a two-inch drop onto the turntable creates a shock

load on the load bearings that will result in their premature failure.

 See the installation page in this manual for instructions on how to install a roll of stretch-wrap

material onto the mast carriage.

The load rating, in pounds, is shown on the machine data plate located on the frame near the gear reducer mounting bracket. It indicates the net capacity of the turntable with a load that is centered and evenly distributed.

Note: The addition of any ancillary equipment to the turntable, such as a conveyor, must be taken into account when determining the maximum working load to be placed on the turntable.
