Tow Arm Assembly
Note that the support brackets which are normally mounted on each end of the crane bridge to be electrified are not included in the system but are supplied by the purchaser. These brackets must be adequate to support the cable tension applied when the adjustment is made to eliminate the cable sag caused by the weight of the trolleys and festoon cable. Normally this will be 1/4" thick angle or channel iron adequately fastened.
The position of the cable on the bridge is determined by the placement of the tow arm assembly. The tow arm must located just under the cable to provide for pushing back on the trolleys when returning to the storage end of the system. Be sure that a suitable place is found to install the tow arm and then place the cable just above the tow arm. It will be necessary to drill a hole in each support bracket for the 3/8" eye bolts which will hold the cable ends.
At the end nearest the junction box where the cable connection is to be made, install the FC-CS4 end clamp assembly. (R-CS4A for round cable) The end clamp assembly has an eye bolt for one end of the support cable. Feed the trolleys onto the support cable and tie them near the end clamp until it is time for a running test. Install the FC-SRCE2 eye bolt and thimble at the opposite end. Draw the 1/4" nylon coated cable through the eye bolt at each end and clamp the end of the cable loop with the FC-SRCC2 U-clamps (2 at each end). Tighten the nuts on the U-clamps to 50 inch-pounds.
Adjust the outside tightening nut on each of the eye bolts until adequate tension is applied. To test for adequate tension, first run the trolleys to the storage end so they are not weighting on the cable. At the center of the system pull down on the cable. If you can pull down more than 1" on a 20 to 60 ft. cable, keep tightening until it does not exceed that amount. The breaking strength of 1/4" nylon covered cable is 4,200#. Then tighten the inside locking nut on the eye bolts at each end of the system.
Untie the trolleys and feed the festoon cable through the saddles until the proper amount for trolley spacing on the system is achieved. Tighten the saddle bolts to hold the cable(s) in place and then run the system back and forth to see that all trolleys run freely.
Then apply power to the system and check through several cycles at slow speed to check under operating conditions.
