Diagram of Fixed Installation (not mounted to vehicle)

Step 1: Create a foundation for the jib. The necessary minimum foundation requirements appear in the diagrams. When the foundation is adequately cured, install 7/8″ jam nuts on each anchor bolts. Wind them to the surface of the foundation. Level across opposite jam nuts by raising or lowering specific nuts until all of the nuts are level. Then, fill the center of the bolt pattern (see below “Overhead View of Foundation” diagram) with grout, e.g. Morta Mix. The top of the grout pedestal should be level with the tops of the jam nuts.
Step 2: Set the crane on the foundation. Align the bolt holes in the mounting plate with the anchor bolts and carefully lower the mast onto the leveling nuts. Install 7/8″ lock nuts on the anchor bolts but leave them loose. Plumb the mast at 90° increments, i.e. check the vertical levelness of the mast at 4 locations equally spaced around the circumference of the mast. Adjust the leveling nuts to fine tune levelness; then tighten the lock nuts against the mounting plate.

WTJ-20 MANUAL

SIGNAL WORDS
This manual uses SIGNAL WORDS to draw attention to uses of the product that could result in personal injuries, as well as the probable seriousness of those injuries. Other signal words call attention to uses likely to cause property damage. Signal words used in this manual appear below along with the definition 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 or other property.

SAFETY INSTRUCTIONS
Material handling is dangerous. Vestil strives to identify foreseeable hazards associated with the use of its products. However, no manual can address every conceivable risk. The end-user ultimately is responsible for exercising sound judgment at all times.
DO not install or use the crane in areas where it will contact electrified wires. Electrocution might occur if the crane, hoist, or load, etc. contacts electrified wires.
Improper or careless operation might result in serious personal injuries. ALWAYS apply operation, inspection, and maintenance recommendations in 29 CFR 1910.179. Contact the occupational safety and health institution of the state where the crane is used for requirements applied to jib cranes. DO NOT use a damaged/malfunctioning jib! Restore the crane to satisfactory condition before returning it to service. DO NOT exceed the capacity of your jib. See SPECIFICATIONS table on p. 2 or p. 3. The weights of the load, hoist, trolley, rigging, and all other equipment attached to the jib must be added together to determine the net weight applied to the jib. The net weight must never exceed the capacity. Always perform the FUNCTION TESTS (p. 8) before each use. Inform all persons in the area to stay out of the area during operation. NO ONE should ever stand beneath or travel under the crane when a load is suspended from it. DO NOT use the jib to lift people. Do not hand from, or sit on, the boom. ALWAYS load the jib as recommended in USING THE CRANE on p. 8. Failure to properly position a load might cause the load to swing when it is lifted. Load swing might result in serious injury. DO NOT use the crane if any label is unreadable, damaged, or missing. See LABELING DIAGRAM on p. 10. Contact Vestil for replacement labels. DO NOT modify the crane! Modifications automatically void the LIMITED WARRANTY on p. 11 and might make the crane unsafe to use.

ASSEMBLING THE CRANE

Insert the mast into the mast receiver. Install the knobs and tighten them against the mast.

Outer boom

Pin the outer boom to the mast through the pivot holes in the boom and the pivot pin holes in the boom receiver. Secure the pin with a hitch pin.
Lift the end of the boom and insert another pin through the selected holes (A-D) in the receiver. Secure it with a hitch pin.
Slide the inner boom into the outer boom. The inner boom has a series of pin holes along its length. Review the diagrams and tables on page 2 or page 3 that match your boom model. Choose a length that is appropriate for your application. Align the selected holes in the inner boom with the pin holes in the end of the outer boom. Insert the clevis pin and secure it with a hitch pin.

INSTALLING THE CRANE ON A VEHICLE
Refer to the EXPLODED VIEWS on page 4 & page 5.

WTJ-20 MANUAL

Step 1: Contact the vehicle manufacturer to determine the appropriate place to install the crane as well as the hardware that should be used to fasten the crane to the vehicle. (Bolt holes in the mounting plate are 9/16″ diameter to accept bolts up to 1/2″). When choosing an installation site, consider the following factors:
a. The vehicle must be able to support the combined weight of the crane and a load weighing 125% of the capacity, i.e. 2,000 lb. x 1.25 = 2500 lb. (1136 kg)
b. The installation location must also be able to withstand the dynamic forces exerted on it by the jib as the vehicle moves.
c. The boom must be able to rotate freely, i.e. without running into the sides of the vehicle.
d. If installing the crane in a fixed position (not on a vehicle; see installation diagrams on p. 4 or p. 5), the supporting surface must be even, level, and capable of supporting the weight of the crane plus a 125% capacity load.
Step 2: The jib should remain completely assembled during the installation. Use the mounting plate of the mast receiver as a template for marking the locations of the bolt holes on the vehicle surface. Drill 9/16″ holes in the locations of the markings for the anchoring hardware.

Step 3: Align the bolt holes in the mounting plate with the holes drilled in step 2. One person should stabilize the jib while the other fastens the mounting plate to the vehicle using the hardware and any backing or stiffeners recommended by the vehicle manufacturer.

Mounting plate with 9/16″ bolt

Step 4: Lift the end of the jib and pin it to the mast at the desired angle. See BOOM ANGLE ADJUSTMENT on p. 8. Confirm that the mast is able to rotate freely through the necessary range by carefully pushing the end of the boom in both directions.

Overhead View of Mast Receiver

Step 5: Connect the power cord to the power supply. On DC- 9/16″ bolt hole powered units, the power supply cord and pendant control cable must be plugged into the winch.

Step 6: Lower and raise the cable hook using the handheld pendant controller. Watch the cable and confirm that it smoothly spools off of and onto the winch drum.

Step 7: Load test the jib by using it to lift a test weight equal to 125% of the rated capacity (2,500 lb.). Inspect both the crane and the vehicle (or supporting surface) after performing the load test. Look for cracks, warps, and other forms of damage at and around the installation site. Repair the site, if necessary, and perform another load test to confirm that problems are resolved.

Mounting plate at bottom of mast receiver

FUNCTION TESTS
Verify that the jib operates normally by performing the tests below. If an issue is discovered, tag the crane “Out of Service”. Restore the crane to normal operating condition before returning it to service.
1. Test the mast bearing: Rotate the boom in both directions. Make sure that it rotates smoothly. Listen for unusual noises. If the crane wobbles or is unusually noisy as it rotates, remove the mast and grease the bearing at the bottom. If lubrication does not resolve the problem, the bearing might need to be replaced. Contact the factory to discuss the problem and to order replacement parts.
2. Test the winch: Lower and raise the load hook. Make sure that the hook moves at a constant rate. The cable should not bind as the winch operates.

WTJ-20 MANUAL

USING THE CRANE
[NOTE: An auxiliary handle is provided with AC-powered winches. It is a means for manually winding/unwinding the cable and should only be used if the winch does not operate (e.g. loss of power). The handle must not be attached when the winch operates under its own power.]

1. Connect the power cord to the power supply. a. AC units: connect to a properly grounded, GFCI-protected, 115V outlet. b. DC units: make sure battery connections are secure.
2. Apply appropriate rigging to the load. 3. Adjust the length and angle of the boom as your application requires. Consult the appropriate SPECIFICATIONS
table on p. 2 or p. 3 to ensure that the load does not exceed the capacity of the crane in its present configuration. 4. The winch is electronically controlled.
a. DC-powered jibs utilize a constant pressure (“dead man”) pushbutton controller. b. AC-powered units are controller with a toggle switch located on the winch body. Press the DOWN button on the handheld controller (DC units), or press the toggle switch in the DOWN direction (AC units). The winch will operate only while a control button is pressed. Releasing a control button will stop the winch and the hook will maintain its position. Lower the hook sufficiently that the load rigging can be attached to it. The load center should be directly below the hook to prevent significant load swing as the load rises. Proper and improper positioning is diagrammed below:

Side view

Hook/cable aligned with centerline of load (red dashed line)

Front view

Side view

Improperly positioned loads

5. Tighten the knobs tightly against the mast. 6. Press the UP button/toggle switch to raise the load. Loosen the knobs and rotate the boom slowly and direct the
load to the desired location. Lower the load so that it is entirely supported by the vehicle before moving the vehicle. NOTE: The winch is designed for intermittent use. Extended use without pause to allow the motor to cool will damage the motor. Maximum continuous run time is 3 minutes.
7. Put the crane into transport configuration: a. Retract the boom. See BOOM LENGTH ADJUSTMENTS on p. 9. b. Remove the pivot pin. Rotate the boom so that it rests against the mast. Strap the boom to the mast to prevent it from bouncing during transport. c. Unplug the winch power cord and store it inside the vehicle whenever the jib is not in use.

Grasp the end of the (inner) boom. 4. Pull the inner boom until the appropriate pin holes in the inner and outer boom segments align. 5. Reinstall the LAP and the hitch pin.
REMINDER: Boom length affects the lifting capacity of the crane. After changing the boom length, consult the appropriate SPECIFICATIONS table on either p. 2 or p. 3 to determine the capacity of your crane.
RECORD OF SATISFACTORY CONDITION (THE “RECORD”)
Before using the crane for the first time, make a written record of the appearance of each part of the crane and how it operates. Thoroughly photograph the unit from multiple angles. Include close range photos of all pivot points, anchoring points, labels, pins and pin holes, the winch, cable and hook. Cycle the winch up and down. Describe how the unit looks and sounds as the winch operates. Measure the throat opening of the hook and record the measurement. Collate all writings and photos into a single file. This file is a record of the unit in satisfactory condition.

INSPECTIONS & MAINTENANCE
Inspect and maintain the unit as described below to preserve satisfactory operability. Compare all inspection results to the RECORD to determine whether a component is in satisfactory condition or requires repair or replacement. Restore the unit to satisfactory condition before returning it to service. If the unit cannot be restored to satisfactory condition, disassemble it and dispose of the parts. The unit must be retested at 125% of its rated capacity anytime the crane is repaired or modified.
Inspect the following at least once per month: 1. Winch and pulleys: Cycle the winch up and down. Confirm that the cable winds off of and back onto the drum smoothly. The hook should not lower on its own. The cable pulley should not be loose or severely worn and should rotate freely as the cable passes over it. 2. Winch cable: Check for reeving, fraying, thinning, bird-caging, & elongating regions. Replace the cable if damaged. 3. Winch power cord: Examine the cord for damage and areas where the outer sheath has been damaged. Repair all damage before using the winch again. 4. Frame elements: Examine the mast receiver, mast, and both segments of the boom for damage, deformation, corrosion, cracked welds, and severe wear. Inspect all pivot points for severe wear. All frame members should be square, rigid, and free of significant rusting. Remove rust with steel wool or a metal bristle brush , clean the areas to remove rust particles, and apply touchup paint to the affected areas. 5. Hook: Visually inspect the hook before each use. Look for deformations and cracks. Immediately discard the hook if it is cracked or if the throat opening is more than 15% in excess of the original throat opening. Discard the hook if it is twisted more than 10° from the plane of the hook in its original condition. Confirm normal operation and operation of the safety latch.

6. Vehicle: Inspect the vehicle where the crane is mounted. Closely examine the area around the mounting plate. Look for rust, corrosion, and metal fatigue. Check the mounting plate (base of the mast), the anchoring hardware, and the vehicle bed/floor particularly around the anchor bolts. Make sure that the mast is securely anchored (i.e. does not wobble). Confirm that anchoring hardware is in normal condition. 7. Labels: Confirm that all labels are in good condition and in place as shown in the LABELING DIAGRAM (below).

Every 6 months: Conduct a load test. Lift a test weight equal to 125% of the capacity. After the test, examine the crane, winch,
cable, and the vehicle where the crane is mounted. Look for deformations, cracks, and metal fatigue. Do not continue to use the crane unless both it and the supporting vehicle are in normal condition.

TROUBLESHOOTING
Always unload the crane and disconnect the winch from the power supply before troubleshooting an issue.
