Outrigger Assembly General

The truck is designed with an non-adjustable outrigger assembly.

Optional baselegs of th e outrigger assembly are adjustable in widths from 32 to 51 in. (813 to 1300 mm) inside dimension to suit different pallet sizes. Normally the baselegs are adjusted to the customer’s specifications prior to delivery.

Support Arm Width Adjustment

Adjustable straddle base legs (support arms) are available as an option. With this option, baselegs are adjustable from 32 to 51 inches (813 to 1295 mm). Baselegs are not adjustable for standard configuration truck with welded baselegs.

NOTE: Think Safety First!

1.Make sure the truck is unloaded and parked on a level surface.

2.Lift the forks high enough to place a toe jack under the frame as shown in Figure7-90. Shut the truck OFF, unplug the battery, and remove the battery.

Maintenance

Check the fastening of the baselegs at the regular 500hours preventive maintenance service. Torque bolts to 180 to 200 ft. lb. (244to271Nm).

3.Jack the truck up on one side just high enough to raise the load wheels off the floor. Allow no more than 1/4 in. (6 mm) between the floor and the load wheel. Place a wood or metal block under the frame as shown in Figure7-91

5.Repeat step 3 for the other side. When blocking the other side, place a carpenter’s level on the side of the mast and make sure it remains level from side to side as shown in Figure7-92 starting point and further adjustments may be necessary.

•(Desired I.D.) Divided by (2) minus 12=Distance between Surface “A” and Surface “B”. See Figure7-94.

6.Remove both side plates by lifting up and out as shown in Figure7-93

9.Move one support arm outward until the width calculated in step 8 is reached. Repeat this step for the other support arm. Tighten bolts to 40 ft. lb. (54.2 Nm) in a cross pattern for both arms.

10.Measure the distance between points “C” and “D” as shown in Figure7-95. If the measurement is less than the desired I.D., adjust each support arm equally until the desired I.D. is reached. Make sure adjustments made to each arm are in equal amount and are torqued to 40 ft. lb. (54.2 Nm) before re-measuring. Make sure the distance between points “A” and “B” on both support arms are equal once the desired I.D. is achieved.

11.Snug the adjustment bolts in the pattern shown in Figure7-89 in 40 ft. lb. (54.2 Nm) increments. Continue in a cross pattern until all bolts are torqued to 180 to 200 ft. lb. (244 to 271 Nm). It is very important that a cross pattern is maintained in 40 ft. lb. (54.2 Nm) increments and that each bolt is torqued between 180 and 200 ft. lb. (244and 271Nm) when finished.

7.Loosen the four adjustment bolts on each support arm.

8.To determine the correct amount of adjustment for the desired Internal Dimension (I.D.), use the calculation shown below. This measurement is a

12.Using a toe jack, remove the blocks under the frame from one side at a time, to return the unit to the ground.

13.Use a carpenters level to check the mast again. Make sure it is plumb and level. See Figure7-92 on page7-86

Load WheelsMast, Chain, Hose, Cable

Load Wheels

Load wheels are mounted on the outriggers to support the rated load of the truck. Load wheels contain bearings sealed on one side.

Load Wheel Removal

Block all wheels to prevent the truck from rolling.

1.Park the truck on a level surface and block the truck from moving.

2.If equipped with the optional keypad, press the red OFF ( O ) key. Place the Main ON/OFF Switch in the OFF position. Disconnect the battery connector from the truck.

3.Jack the truck as shown in Figure7-96, sufficient enough to remove set screw [3]. Block the truck with wood or steel block.

4.Remove the axle set screw [3].

Figure 7-96.Jacking Load Wheels

Load Wheel Installation

1.Install the bearings in the new load wheel.

2.Place the new load wheel upright on a flat surface. Position the bearing over the load wheel. Place a flat metal plate over the bearing and hammer the bearing in place with a plastic mallet. Make sure the bearing is fully seated in the load wheel.

3.Align the load wheel assembly (see Figure7-97) into the load arm.

4.Drive the axle through the load arm hole and wheel. Align the “dimple” in the axle with the set screw hole.

5.Install and tighten the set screw. Figure 7-97.Load Wheel Assembly

5.Drive the axle out of the load arm casing with a hammer and drift pin.

6.Push the wheel out.

7.If the bearings [5] are to be reused, insert a brass drift pin into each end of the load wheel and knock out the bearings.
