Fork Mounted Door Demon®



Unit's Physical Dimensions:

28" D x 15" W x 11" H
Operating Weight: 200 lbs.



NEW FOR 2012: 20% Torque Power Increase. We are now using a new Char-lynn drive motor that provides the extra torque you need!

This is our most economical powered door opener but still is as strong as the rest. We use a Char-Lynn motor made by Eaton to turn the Capstan. This unit will tie into your hydraulic system via the utility connectors and will be operated by the driver from his seat.

A flow control on the Demon will regulate the flow to 2 gpm. Most forklifts operate above our desired flow and this is usually not a problem. You might check this before purchasing a unit.

This Door Demon® will turn at 12 rpm; the shaft length is totally manufactured to your need. We will make it fit on any forklift, it’s not that hard.



Product Features:

Uses Fork device hydraulics/requires 2 gpm @ 2950 psi
Lift operation controls direction from seat of lift
Mounts to any fork device
Limited scheduled maintenance
