High-starting torque continuous duty motor with overload protection
A brake band hold-down for a mechanical dock leveler includes a frictional brake that grabs the hold-down when the ramp is at the proper elevation.
If additional upward force (this can happen when trailers move up and down when trucks are loaded or unloaded) is applied to the ramp the frictional brake will give way just enough to accommodate the change.
This prevents the dock leveler ramp from being damaged.
Shutters can be up to 13'- 6 inches wide and 12 feet tall with UL labels Class A B or C while still being able to function as normal counter rolling shutters.
Oversized fire shutters can be manufactured up to 20 feet wide
