RT60 Rough Terrain Crane 07 - 1
7.1 SAFETY EQUIPMENT
Anti-Two Block System
Examine the anti-two block switches on the boom, the jib and auxiliary sheave heads for
damage. Make sure that the switch weights operate correctly and they are on the lift
cable in the correct position. Examine the electrical equipment and wires that attach to
the cable reel. Do an inspection of the wires along the length of the cable. Look for
indications of wear, damage or incorrect installation. Make sure that the tension on the
spring-loaded cable reel is correct and that the reel turns freely.
Note
When you do a check of the anti-two block switch function, you must move the
anti-two block weight with the hook block.
Rated Capacity Indicator
When the actual load is near the rated one, it sends out acoustic sound. You can only do
safe crane movements that are on the screen at this time. Move the load into a permitted
condition to stop alarms and continue correct crane operation. For details, please refer to
Rated Capacity Indicator Manual.
Emergency Stop
(1) You can find the emergency stop button on the lower left side of the dash.
(2) When you push the button, all crane operations immediately STOP (includes the
engine). Turn the button clockwise to release it and continue usual crane operation.
(3) Only use the EMERGENCY STOP BUTTON in a clear emergency!

Wrap
When there are only 3 wraps of wire rope remaining on the winch, the winch (main or
auxiliary) does not turn. When this occurs, you can only do “Boom Retract” and “Winch
up” operations.
Seat Occupied Indicator
(1) This indicator illuminates when the seat switch is activated by sitting in the operator
seat.
(2) The seat switch controls the functions of the left and right joystick as well as the
boom telescoping extend/retract foot pedal.
(3) Only when the operator's seat is occupied and the icon on the display is lit
will the crane functions be active (via joystick and telescoping pedal).
When driving the crane, the joysticks and boom extend/retract pedal
remain active. Crane operations can occur if either joysticks or pedal are
used unintentionally.
