Harrington Hoists TCR Non-Stationary Application, Preoperational Checks and Trial Operation

3.11.1 CAUTION

3.10Non-Stationary Application

3.10.1For applications such as rental fleets or construction sites where the hoist is moved from place-to- place, a filter and lubricator are still required. Consult factory for recommended methods.

3.10.2Connections and fittings must be kept clean and care taken to prevent dirt, debris and moisture from entering the hoist.

3.10.3Recommended practice for removing the hoist from an installation:

Run the hoist briefly with well lubricated air

Disconnect the air supply line

Inject a small quantity (approximately 20 drops) of oil into the hoist’s inlet port

Plug the inlet port

3.11Preoperational Checks and Trial Operation

Check for the availability of required operating air pressure of between 60 PSI to 90 PSI at the hoist's inlet port before trying to operate the hoist.

3.11.2 WARNING Verify that the load chain is not twisted or tangled and that the bottom hook is not capsized prior to operating the hoist. Correct all chain irregularities before conducting the first hoist operation. See Figures 3-5and 3-6.
