Check Cable Wear

The wire rope (cable) that raises and extends the mast is a very important part of the light tower. There is one cable/ hand winch system, located on the tongue of the trailer, that raises and extends the light tower mast. There is a second cable/hand winch system located on the mast that serves to raise and lower the two extendable sections of the mast.

DANGER

Wire rope (cable) will fail if it is worn, frayed, misused, crushed, kinked or damaged in any way. Always check the cables and pulleys for any abnormalities before use.

Do not use it if there is even the slightest cause for concern and replace any damaged cables or pulleys immediately.

Servicingthe Mast Raise/Lower Cable System:

To replace any components in the mast raise/lower cable system, use the following steps (See Figure 19):

Figure 19. Mast Raise/Lower Cable System

1.Lower the mast to the horizontal resting position.

2.Inspect the cable clamps, pulleys, and other components for worn or damaged parts.

3.Disconnect the cable from the winch and remove from the mast pulley and cable sheave. Detach the cable from the hand winch as necessary.

4.Replace the pulley and the cable as needed.

5.Rethread the cable through the pin and pulleys and reattach the cable to the winch.

6.Raise and lower the mast several times to verify correct operation.

Servicingthe Mast Extension Cable System:

To replace the cable in the mast extension cable system, use the following steps (See Figure 20):

1.Lower the mast to the horizontal resting position.

2.Inspect the cable clamps, pulleys, and other components for worn or damaged parts. If either of the cables on the mast needs to be replaced, they should both be replaced at the same time.

3.Disassemble the mast by disconnecting the cables from the mast and sliding the sections apart. Plastic guides and lock bolt must be removed. The lower cable can be disconnected from the winch.

WARNING

The mast sections are heavy and awkward to handle. Use proper lifting devices and procedures when servicing the mast and its components.

4.There are two pulleys in the mast raise/lower cable system. They should be removed and replaced if worn or damaged. Worn or damaged pulleys can cause premature cable failure.­

5.Reassemble the mast extension cable system by connecting the cable to the bottom of the upper mast and sliding the upper mast into the opening of the center mast. Connect the second cable to the bottom of the center mast and slide the center mast into the opening of the lower mast, observing proper lifting techniques.
