H-style operators include a floor level chain hoist to ease manual operation in an emergency or power outage.
The operators are typically mounted to the wall when used with larger sectional overhead doors with vertical or high lift and mounted to the wall or the front of the hood when used with rolling doors and grilles.
H operators are attached to the door jackshaft to indirectly drive the door.
With the addition of the 828LM MyQ technology enables the user to monitor and control their operator and light with their smartphone tablet or computer.
Alerts can be received as email or pop-up (push) notifications on a mobile device ensuring the status of your commercial door.
Security+ 2.0™ safeguards your facility – with every click a new code is sent to the commercial door operator so the door opens only for you.

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.
