RT75 Rough Terrain Crane

Know the weight of the hook and rigging.

Know the boom length, jib length, and the area where you have to move the load.

Use next lower rated capacity when working at the boom length or radius between the
figures on the rated lifting capacity chart.

Do not lift a load until you know if the load is less than the capacity limit of the crane.

Only operate with the recommended counterweights. It is dangerous if you do not use
the approved charts to calculate the decrease or increase in counterweight.

Do not lift the load if winds are dangerous. If necessary, lower the boom.

See the
Load Ratings
for possible restrictions.

Avoid side loading.

Do not let the load or other objects hit the boom.

Release the load slowly, be sure the boom does not tighten against back stops.

Put the boom point directly above the load.

Be sure that the load hangs freely.
J. Operation setup

Be sure the load-bearing surface can hold the weight of the crane and load.

Make crane level, check frequently, and re-level them when necessary.

Assemble barricades to keep personnel out of the load move radius.
K. Power line safety

Find power lines in the area before you start a task. Follow national and local
regulations and ANSI B30.5 when you operate around power lines.

Do not remove the material from below power lines if the boom or crane can touch the
lines.

Do not let the crane or load touch electrical lines. Do not go near the minimum
permitted clearance for operation of a crane near electrical lines.

If you touch the electrical lines, stay on the crane until the boom moves off the lines or
until the power line current is off.

Keep all personnel off the crane if it touches power lines. If you must move from the
crane, JUMP, DO NOT STEP OFF. Jump with feet together.

Use a signal person when you operate around power lines
L. Slip and fall prevention

Make sure that you stop the crane before you move on and off the equipment. Do not
jump.

Do not use the controls and the steering-wheel as hand holds.
