SAFETY INFORMATION RT770E OPERATOR MANUAL
2-34 Published 04-04-2017, Control # 446-09
• Check for proper functioning of all controls and operator
aids (for example, RCL).
• Check all braking (for example, wheel, hoist, and swing
brakes) and holding devices before operation.
You must ensure that the outriggers and jack cylinders are
properly extended and set before performing any lifting
operations. On models equipped with outriggers that can be
pinned at the mid-extend position, the outriggers must also
be pinned when operating from the mid-extend position.
Clear all personnel from the outrigger area before extending
or retracting the outriggers. Carefully follow the procedures
in this Operator Manual when extending or retracting the
outriggers. Death or serious injury could result from improper
crane set up on outriggers.
Be familiar with surface conditions and the presence of
overhead obstructions and power lines.
Working
Operator shall be responsible for all operations under his/her
direct control. When safety of an operation is in doubt,
operator shall stop the crane’s functions in a controlled
manner. Lift operations shall resume only after safety
concerns have been addressed or the continuation of crane
operations is directed by the lift supervisor.
Know the location and function of all crane controls.
Make sure all persons are away from the crane and the
Travel Select Lever is in the “N” (Neutral) position with the
Parking Brake engaged before starting the engine.
Sparks from the crane’s electrical system and/or engine
exhaust can cause an explosion. Do not operate this crane
in an area with flammable dust or vapors, unless good
ventilation has removed the hazard.
Carbon monoxide fumes from the engine exhaust can cause
suffocation in an enclosed area. Good ventilation is very
important when operating the crane.
Before actuating swing or any other crane function, sound
the horn and verify that all personnel are clear of rotating and
moving parts.
Never operate the crane when darkness, fog, or other
visibility restrictions make operation unsafe. Never operate a
crane in thunderstorms or high winds.
Always be aware of your working environment during
operation of the crane. Avoid contacting any part of the crane
with external objects.
Clear all personnel from the counterweight and
superstructure area before removing the counterweight.
Keep unauthorized personnel clear of the working area
during operation.
Only the crane operator shall occupy the crane when in
operation.
You must always be aware of everything around the crane
while lifting or traveling. If you are unable to clearly see in the
direction of motion, you must post a look out or signal person
before moving the crane or making a lift. Sound the horn to
warn personnel
Operate the crane only from the operator’s seat. Do not
reach in a window or door to operate any controls.
Operate the crane slowly and cautiously, looking carefully in
the direction of movement.
A good practice is to make a “dry run” without a load before
making the first lift. Become familiar with all factors peculiar
to the job site.
Ensure the hoist rope is properly routed on the hook block
and boom nose and that all rope guards are in place.
