Moving the Load
Ensure reaction bar anchor is properly engaged to the reaction bar. See
Figure 3.
2.5.1
MOVE THE LOAD
slowly and smoothly, only a small distance at first.
Make sure the load is balanced and securely attached before continuing.
2.5.2
USE THE FOOT PEDAL CONTROL to operate the unit. The foot pedal
control should be a momentary contact type, so the unit will stop when the
operator releases the control.
2.5.3
OBSERVE THE SYNTHETIC FIBER ROPE as it winds onto the
drum. Keep tension on dead end of rope. If it becomes loose, uneven, or
overlapped, stop the operation and rewind the synthetic fiber rope before
continuing.
Continued operation with overlapped or uneven synthetic
fiber rope can damage the synthetic fiber rope and shorten its life.
A rope cleat can be used to temporarily hold dead end of rope.
DO NOT
LEAVE LOAD UNATTENDED.
2.5.4
OBSERVE THE REDUCER during operation for signs of overheating.
Frequent overheating may be a sign of damage, or may indicate the
need for a larger power unit.
a
WATCH FOR SMOKE, the smell of burnt lubricant, and other signs
of overheating. Use a thermocouple or other device to monitor reducer
temperature.
b
STOP THE OPERATION if the reducer overheats, and allow the unit to
cool.
Continued operation may cause damage.
Important!
• Obey a stop signal from anyone.
• Maintain tension on the synthetic
fiber rope to keep it tightly and
evenly wound on the drum.
• If the unit and load are not visible
during the entire operation, get
help from another person.
• Appoint a supervisor if more
than one person is involved in
the operation. This will reduce
confusion and increase safety.
