7. Lower the hook block to the load and fasten the hook.
Before making any crane lift, make sure the hook is properly engaged with the slings, or lifting
device employed to make the lift. Be certain the hook latch is not supporting any of the load.
Hook latch is intended to retain loose slings or devices under slack conditions. It is
not intended to be an anti-fouling device, so caution should be used to prevent the
latch from supporting any of the load. Periodic inspection of the latch must be made
to insure its proper operating condition.
Hoisting or lowering of the load with the MAIN winch is controlled by the RH Joystick. LOWER the
load by pushing the RH joystick FORWARD and RAISE the load by pulling the RH joystick BACK.
Improved control is obtained by operating the engine at low speed while “metering” the control.
Always actuate and release this joystick slowly to minimize dynamic effects of the load and to
prevent “bird nesting” of the cable on the winch drum.
To shift the MAIN winch into the high-speed, select high speed using the two speed switch located
on the upper portion of the RH joystick. When slowing the winch, slowly return winch lever to
neutral position to bring the load to a gradual stop. The MAIN winch can be disabled by selecting
the center switch on the RH Joystick.
Hoisting or lowering of the load with the AUXILIARY winch is controlled by the LH Joystick. LOWER
the load by pushing the LH joystick FORWARD and RAISE the load by pulling the LH joystick
BACK. Improved control is obtained by operating the engine at low speed while “metering” the
control. Always actuate and release this joystick slowly to minimize dynamic effects of the load and
to prevent “bird nesting” of the cable on the winch drum.
To shift the AUX winch into the high-speed, select high speed using the two speed switch located
on the upper portion of the LH joystick. When slowing the winch, slowly return winch lever to neutral
position to bring the load to a gradual stop. The AUXILIARY winch can be disabled by selecting the
center switch on the LH Joystick.
8. Lift the load to the desired height. It is good operating practice to not lift the load any higher than
necessary.
The crane is equipped with an ATB system which includes a warning light, audible alarm, and
control disconnects. When the hook block or ball activate a correctly installed and maintained ATB
system, the block or ball will not raise, the boom cannot be extended and the boom cannot be
lowered. To return to an operating condition, either lower the hook or ball, retract or raise the boom.
The operator may need to raise the hook block beyond the point at which the ATB system is
activated during rigging or travel. The operator may override the system. (shown in control and
instrument sections).
Continuing to pull the block up after contact has been made with the boom head
may damage the boom head and sheaves or break the cable, causing the load to
drop.
