BALL BEARING TROLLEY
SERVICE INSTRUCTIONS AND PARTS LIST
MODELS CBTP AND CBTG 1/4 THRU 5 TON
This trolley is a relatively simple mechanism requiring
comparatively little care, maintenance, inspection and
lubrication. The following information is provided to
assist in installing and maintaining this equipment.
INSTALLATION
Sliding the trolley over the open end of the runway
beam is the simplest way to install this unit. If an
open beam end is not available, one side plate can be
removed and the unit can be reassembled on the
beam. Always verify the trolley is adjusted properly to
fit the beam. See the adjustment instructions below
and the diagram to the right. Always run the unit
along the entire length of the runway beam to verify
proper operation and clearances.
GENERAL MAINTENANCE
Thorough inspection is recommended at regular
intervals. The frequency of inspection must be
determined by the user, since application factors such
as duty cycle and ambient conditions will dictate the
maintenance requirements of the unit. When
inspections are made, the entire trolley should be
inspected for wear, or for damage such as may be
sustained through severe overloading or impact with
other objects. Replace all damaged parts
immediately. Check trolley motion along the runway
beam, to verify proper operation.
LUBRICATING THE TROLLEY
1/4 thru 5 ton trolleys are built with sealed, life-time
lubricated precision ball bearings that should require
no further lubrication. Periodic lubrication of the
geared trolley drive shaft support block is
recommended. A small amount of medium grade
motor oil should be applied in the oil hole provided in
the top of the drive shaft support block.
ADJUSTMENT INSTRUCTIONS
The beam flange width plus approximately 1/16”
running clearance on each side of the flange is the
correct trolley setting with the total beam to wheel
flange clearance not to exceed 3/16". Move the
spacing washers to the inside or outside of the side
plates as required. After adjustment, tighten the
trolley pin nuts and the locking nuts securely.
