Ratchet Lock
•
The ratchet lock can be activated or deactivated, depending upon the application.
Operation with Ratchet
•
The ratchet on the EXPCRL is spring loaded. It is designed to function in all acceptable
mounting configurations.
Operation without Ratchet
•
Deactivate the ratchet by pivoting the lock-out bar to the lower position. This will remove the ratchet
pawl from the path of the ratchet plate. Locate the dimple on the lock out bar in the hole provided.
Roller Guide Locations
WARNING:
Do not activate the ratchet abruptly. Sudden activation may cause excessive shock loads to the ratchet pawl which may
cause lock-up and/or breakage.
Cable Installation
Cable is factory installed and sealed. Consult factory for changes.
Spring Tension Adjustment
WARNING:
Do not allow cable to retract without restraining the retraction speed. Walk the cable back to the reel during the spring
tension adjusting process. Always maintain two full cable wraps on drum at maximum cable extension, size cable accordingly.
1. The EXPCRL reels come with pre-tension from the factory. Some adjustments may be required to meet specific application
requirements.
2. To assure that the cable will retract properly and operate under the correct tension for intended application; the reel should be
tested. Securely mount reel before testing with cable installed on drum and end of spool cable not connected, proceed with the
next steps.
3. Pull the cable out to the intended travel distance and allow it to rewind. This procedure should be repeated five (5) to ten (10)
times in order to set the spring. Walk the cable back to the reel during the spring tension adjusting process.
Rotate Spool while holding Cable to Test the Spring Tension
4. With all the cable wound on the reel, grasp the end of the cable and rotate the drum and cable together in the direction of pay
out in order to pre-tension the spring. The number of pre-tension turns is determined by cable size and footage. Usually, four to
sixteen turns is sufficient, but additional turns may be used if testing indicates that the cable will not fully retract as desired with
just four turns.
