Gearhead style commercial door operators employ lubricated gears for heavy industrial high cycle applications.
GH-style operators include a floor level chain hoist to ease manual operation in an emergency or power outage.
Hoist wheel is easily moved to Right or Left hand side of unit eliminating the need to order right or left hand mounting.
MyQ Technology enables you to securely monitor and control your facility operator with your smartphone tablet or computer. Internet Gateway 828LM required.
Security +2.0 radio receiver safeguards your facility - with every click a new code is sent to the commercial door operator so the door opens only for you.
Timer-To-Close: Conveniently and confidently closes the commercial door automatically after a predetermined amount of time has elapsed for added security and peace of mind.
The travel nut on LA500DC and LA500DCS gate operators may break when excessive force is applied to the gate such as being struck from a vehicle.
The travel nut can be identified as the white plastic nut that attaches to the internal lead screw of the arm.
The symptom of this problem is that the trolley assembly slides back and forth along the guide slots without mechanical restraint.
LiftMaster has created Trolley Service Kit K75-39337 with all the necessary parts and provides instructions on how to replace a damaged travel nut
within an LA500 arm
Electromechanical slide-in edge for sectional doors.
With appropriate mounting channel this edge will fit nearly all doors from 1-1/2" to 2" thick. The ME116 has been designed to fit all CHI doors with double track bottom retainers.
ME116 is resistant to flame water and most common greases and oils
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.
Used on docks where excessive friction from up and down trailer
movement occurs (yard jockeys air ride trailers etc.).
Can be used in material handling application where medium to heavy dock
protection is required
“Gliding” heavy-duty steel face is 3/8” thick and independently anchored with elongated holes to face of bumper allowing bumper to compress AND offer high surface abrasion resistance
Rubber pads laminated between steel angles and secured with 3/4” rods
Bumper is fastened to dock surface with 3/8” steel angles and/or flat plates depending on the model chosen.
