RT530E-2 OPERATOR’S MANUAL SET-UP AND INSTALLATION PROCEDURES
Unlock
NOTE: Always remove the switch lock (enable) before
installing an A2B weight around the hoist rope.
1. (A) Pull down lanyard (2) and remove cap (1). Switch is
unlocked (enabled).
2. (B) Install cap (1) on A2B switch.
Before Operation
Check the following electrical connections before operating
the crane to ensure the RCL system is properly connected
for the crane configuration.
Cranes with Main Hoist Only
If the crane is operated only with the boom and without boom
extension or lattice extension, no additional connections are
necessary. It must however be ensured that the A2B switch
weight is correctly mounted on the main boom hoist rope.
With even numbers of rope lines, the lifting limit switch
weight shall be attached to the "dead end" of the hoist rope.
With odd numbers of rope lines, the lifting limit switch weight
shall be attached to the rope line with the lowest operating
speed.
If the crane is operated with a main boom extension or top
section, the connecting cable must be mounted between the
distributor socket on the lattice extension and the distributor
socket on the main boom. The main boom A2B switch weight
must be disconnected and mounted on the extension or fly
boom A2B switch.
Machines with Main and Auxiliary Hoists
If the main boom extension or fly section is not used, then the
bridging plug must be plugged into the distributor socket on
the main boom and the lifting limit switch weight must be
mounted on the main boom.
If the crane is operated with a main boom extension and/or
with a lattice extension, then the connecting cable must be
mounted between the distributor socket on the extension or
on the top section and the distributor socket on the main
boom. In addition, weights must be fitted to both the A2B
switch of the main boom and the extension or fly section.
If the boom extension or lattice extension are in working
position and if the main boom is not equipped with a hoist
rope, then the weight of the A2B switch on the main boom
must be removed to prevent endangering personnel or
damaging equipment.
After electrical connections have been checked to ensure
the system is properly connected for the respective crane
configuration, the following checks must be made:
1. Check electrical wiring connecting various parts of the
system for physical damage.
2. Check A2B switches and weights for free movement.
3. Inspect spring cable drum for smooth running, initial
drum tension, and correct cable winding.
WARNING
Failure to reposition the A2B weight will prevent the A2B
system from functioning properly. No weight shall be
mounted on the A2B switch of the main boom when
working with the extension/top section.
