Electromechanical slide in edge for 1" to 2" sectional doors.
Touch sensitive signaling allows for immediate stopping or reversing of motion. The ME117 is resistant to water flame and most common greases and oils.
Doors used with this operator should be balanced with the ability to be manually lifted by hand in an emergency or power outage.
These operators include a door lock sensor to prevent damage to the door and operator caused by attempts to automatically open a locked door.
The operators are typically mounted to the wall when used with smaller sectional overhead doors with vertical or high lift and mounted to the side or the front of the hood when used with rolling doors and grilles.
DJ operators are attached to the door jackshaft to indirectly drive the door.
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.
