TMS800E OPERATOR’S MANUALSET-UP AND INSTALLATION

Removable Counterweight

Danger

Ensure that all mounting pins are properly installed and locked, during, and after operating the counterweight removal system.

• The 5443 kg (12,000 pound) removable counterweight consists of three slabs, each weighing 1814 kg (4000 pounds).

• The 8165 kg (18,000 pound) removable counterweight consists of three slabs each weighing 1814 kg (4000 pounds) and one slab weighing 2721 (6000 pounds).

• An optional 10,885 kg (24,000 pound) removal counterweight consists of two 1,360 kg (3000 pound) “wing weights” that hang on the existing 8,165 kg (18,000 pound) counterweight stack.

NOTE: This extra counterweight is not roadable due to the overall width of the machine when installed, but you can move around the jobsite with the full counterweight installed.

The following procedures are applicable for removal and installation of any or all pieces (Figure 4-8).

The counterweight contains lugs for attachment to the removal cylinders and lugs to pin it under the hoist mounting. The additional slabs pin the structure to each other. The counterweights can be pinned to the carrier deck and are transferred between the turntable and the carrier deck and by two hydraulic removal cylinders. The cylinders are controlled from a valve assembly located under the hoist mounting. The valve contains an inlet section, an outlet section with relief valve, and a working section for each cylinder. The valve is manually controlled by levers extending through the turntable side plates on each side.

Mounting the Counterweight

1. Position the crane on a firm level surface. Fully extend and set the outriggers.

2. Rotate and align the rear of the superstructure above the removable counterweight stowed on the carrier deck. Engaging the pin type turntable lock will aid alignment.

3. Using the counterweight removal control valve levers located on either side of the turntable, lower the counterweight cylinders. Pin the cylinders to the counterweight using the attach pins in the cylinders. Insert the retaining pins in the attach pins.

4. Push in, turn, and remove the long attach pins from the counterweight and carrier frame lugs.

5. Using the control levers, raise the counterweight up under the superstructure frame.

NOTE: It may be necessary to jog the counterweight removal control levers (Fig ure 4-8) to install the upper attach pins.

6. Remove the upper attach pins from the stowage bushings and install them into the upper counterweight and superstructure frame lugs.

7. Push in on the pins and turn to lock pin in the notch.

8. Insert the long pins into the bottom of the counterweight. Push in on the pins and turn to lock pin in the notch.

9. The crane is now ready for operation with the counterweight installed.

Stowing the Counterweight

1. Position the crane on a firm level surface. Fully extend and set the outriggers.

2. Rotate the superstructure to align the counterweight with the stowage area. Engaging the pin type turntable lock will aid alignment.

NOTE: It may be necessary to jog the counterweight removal control levers to remove the weight of the counterweight from the upper attach pins.

3. Using the counterweight removal control valve levers, raise the counterweight cylinders to relieve weight on the upper attach pins. Push in, turn, and remove the upper attach pins from the superstructure frame lugs and the counterweight

4. Stow the upper attach pins in the bushings on the side of the superstructure.

5. Push in, turn, and remove the long pins from the bottom of the counterweight.

6. Using the removal control levers, slowly lower the counterweight onto the carrier stowage area.

7. Insert the long pins through the carrier lugs and counterweight. Push in and turn to lock pin in the notch.

8. Remove the attach pins from the counterweight lugs and cylinder ends. Raise the cylinders and stow the attach pins in cylinder and insert retainer clip pins.

9. The carrier is now ready for highway travel with the counterweight stowed.
