Improve the safety and control of manually operated rolling doors with the ControlGard® Chain Hoist.

Unlike a conventional chain hoist that may allow a heavy rolling door to descend rapidly if the hand chain is released or mishandled, the ControlGard uses an integrated braking system that keeps the door under control throughout operation.

The door moves only while the operator is actively pulling the hand chain. When the chain is released, the internal brake automatically engages and holds the door in position.

This controlled operation makes the ControlGard an excellent choice for commercial rolling steel doors and rolling grilles where dependable manual operation and improved door control are important.

Integral Braking System

The key advantage of the ControlGard is its integrated brake.

With many conventional chain hoists, improper operation can allow a rolling door to gain momentum during closing. This can cause the door to descend rapidly and may cause the hand chain to move unexpectedly.

The ControlGard provides a more controlled operating system:

Pull the chain: The door moves.

Stop pulling: The brake engages and the door stops.

This allows the operator to maintain positive control of the rolling door throughout the entire opening and closing cycle.

Hold the Door at Any Position

Because the integral brake holds the door whenever the hand chain is released, the ControlGard allows the rolling door to remain partially open when needed.

This can be especially useful for:

• Loading operations

• Ventilation

• Material transfer

• Temporary access

• Maintenance

• Partial-height openings

A conventional chain keeper is generally unnecessary because the brake itself maintains the door position.

Helps Extend Door Life

Controlled operation can help reduce unnecessary stress and abuse on rolling door components.

By preventing uncontrolled descent and abrupt stopping, the ControlGard can help reduce wear on components such as:

• Curtain assemblies

• Bottom bars

• Slats

• Guides

• Brackets

• Shafts

• Bearings

• Drive components

Compact Design

The braking mechanism is incorporated directly into the chain hoist, eliminating the need for a large external governor.

The system requires approximately 3-1/2" of side clearance, making it suitable for many commercial rolling-door installations where available headroom or sideroom is limited.
