push solenoid function.
Crane Precautions
1. Movement of the control levers should be
slow and smooth to meter oil flow for safe
operation. Avoid jerky and sudden
movements.
2. The crane controls should be clearly
marked with decals. If these are missing or
illegible,replace immediately. (See Chapter
5: Decals)
3. Lift load slightly off the ground to check the
safety of the cargo. Do not use stability to
determine the safety. Consult the capacity
charts and strictly adhere to them.
4. Be constantly aware of the boom position
when operating the controls.
5. The boom tip should be centered directly
over the load before making the lift to
avoid swinging.
6. Do not drag loads with the crane.
7. Do not attempt to lift fixed loads.
8. Do not load boom in a sideways direction.
9. Know the weight of the rigging and load to
avoid overloading the crane.
10. Do not extend or rotate a load over
anyone.
11. Wear protective gear such as hard hat,
safety glasses, steel-toed boots, and
gloves.
Hook Precautions
1. Hooks are designed and manufactur
ed to
lift specific loads. The specified rated load
of a hook applies to loads held uniformly in
direct tension and does not take into
account shock loads, hook tip loading, side
loading, bending, torsional, or related loads.
2. Do not attempt to lift a load that is larger
than the load rating of the hook.
3. Never use a hook’s yield point as an
indicator of its capacity.
4. Do not use a hook to lift personnel.
5. Know the rated load of the hook in use.
6. Never weld attachments to a finished hook
in field applications. This will alter and
destroy the design properties of the hook
material.
7. Keep fingers, hands, body, and loose
clothing from between the hook and the
load.
8. Avoid shock loading.
9. Inspect the hook regularly for excessive
wear and maintain it in safe operating
condition.
