The four most important aspects of trolley operation are:
1.
Follow all safety instructions when operating trolley.
2.
Allow only people trained in safety and operation on this
product to operate trolley.
3.
Subject each trolley to a regular inspection and
maintenance program.
4.
Be aware of the trolley capacity and weight of load at all
times.
Operators must be physically competent. Operators must have
no health condition which might affect their ability to act, and
they must have good hearing, vision and depth perception. The
trolley operator must be carefully instructed in his duties and
must understand the operation of the trolley, including a study of
the manufacturer’s literature. The operator must thoroughly
understand proper methods of hitching loads and should have a
good attitude regarding safety. It is the operator's responsibility
to refuse to operate the trolley under unsafe conditions.
WARNING
• The trolley is not designed or suitable for lifting, lowering
or moving persons. Never lift loads over people.
• Do not side load or “yard” a load with a powered trolley.
Motorized Trolley Operation
The motorized trolley is used to move SUSPENDED loads over
the length of the runway. The trolley motor is not a variable
speed motor it has only one speed. For loads to be positioned
accurately the trolley direction button on the pendant may be
bumped (pushed momentarily). Trolleys are available with a two
speed option. On two speed trolleys, select the high speed
setting when moving between stations.
• A swinging load can cause injury and/or damage to
property. Do not allow load to swing freely. Maintain
contact with load at all times.
Use the low speed setting when accurate load positioning is
required. A swinging load has a large amount of force while it is
swinging freely. Care should be taken to prevent the load from
swinging.
Before starting the motorized trolley, ensure that load is lifted
clear of the ground. Observe the path to be covered and warn
any personnel in the area. Do not combine hoisting and moving
operations. Either lift, lower a load or travel a load, do not do
both.
WARNING
• When using motorized trolleys lift the load only high
enough to clear the ground or any obstacles.
• Do not side load or “YARD” a load with a powered trolley.
• Do not lift or move any load over people.
Initial Operating Checks
Trolleys are tested for proper operation before leaving the
factory. Prior to placing the trolley into service the following
initial operating checks should be performed.
1.
After installation of trolley, check to ensure the hoist is
centered and secure.
2.
Check connections and position of all electrical supply
cords and plugs.
3.
Operate trolley along the entire length of the beam.
4.
Check trolley and hoist performance when raising, moving
and lowering test load(s). Hoist and trolley must operate
smoothly prior to being placed in service.
5.
Check that hoist is properly installed on hanger shaft and
centered with the hook latch engaged.
Control Pendants
Standard pendants for “Quantum” series electric trolleys
provide push button control for the following functions. Refer to
Dwg. MHP0852:
Hoist Down / Up
Trolley Left / Right
Single or Dual speed
Emergency Stop (red button)
Ensure hoist and motorized trolley operation matches direction
of pendant buttons.
(Dwg. MHP0852)
Dual speed operation control pendant buttons have two
positions. Depressing the button to the first position produces
normal speed. Depressing the button to the full extent of its
travel produces high speed.
Emergency Stop
The emergency stop button will remain depressed after
activation. To reset twist (rotate) emergency stop button
clockwise until button releases and spring returns to its original
position. When a hoist and trolley combination is used the
emergency stop is integrated in the trolley relay box.
