Counterweight Change - (T300-1 Only)
In some cases it may be desirable to change the counterweight on the T300 for use in
locales where it can be advantageous to have a heavier or lighter crane, with the
corresponding change in rated lift capacity.
When the configuration of the crane is changed, the RLI must be programmed to match the
physical configuration of the crane.
Procedure for Counterweight & Greer Computer HEX File Change
1.
Determine the desired counterweight of the crane and matching load chart. See the
Parts book (Group 13) for the required configuration of the desired weight.
2. Remove or add the counterweight to the front bumper and install the appropriate
bumper cover. If adding counterweight, bolt it to the frame with the specified fasteners.
3. If equipped with Aux Winch:
3A. Wrap all of the cable onto the winch and secure the end of the cable so it will not
be damaged or work free.
3B. Disconnect all electrical connections to the winch and secure the wires to insure
they will not be damaged.
3C. Disconnect and cap all hydraulic connections. Make note of where each hose
goes for reassembly.
3D. Remove the bolts securing the winch to the counterweight.
3E. Using a suitable lifting device, lift the Aux winch off of the crane and place it aside.
4. Attach a suitable lifting device to the counterweight and support the weight of the
counterweight with the hoist or crane that will be used for the counterweight removal.
5. Remove the bolts holding the counterweight to the rear of the superstructure.
6. Lift the counterweight off of the crane and place it aside.
7. Remove the paper copy of the load chart from the crane.
8. Lift the new counterweight onto the crane.
9. While still supporting the counterweight, install the hardware securing the
counterweight to the crane and torque fasteners as specified in the chart below.
10. If not using Aux Winch, install additional counterweight as specified.
11. If using Aux Winch:
11A. Lift the Aux winch into position on the counterweight.
11B. Install and torque the fasteners holding the winch to the counterweight as
specified in chart below.
11C. Re-attach the hydraulic hoses to the winch, each in their original locations.
11D. Reconnect all of the electrical connections to the winch.
11E. Re-install the cable per operating instructions.
