Make large commercial doors easier to operate manually with this Wall-Mount Gear-Reduced Chain Hoist Drive, designed for compatible door systems using a 1-inch shaft.

The heavy-duty 4:1 gear-reduction system provides increased mechanical advantage, allowing the operator to raise and lower a properly balanced commercial door with less pulling effort and improved control.

Designed for wall-mounted applications, this complete manual hoist system is ideal for compatible rolling steel, vertical-lift, and high-lift commercial doors.

Key Features

• Heavy-duty manual chain hoist

• Wall-mount configuration

• 4:1 gear-reduction ratio

• Designed for compatible 1" door shafts

• Reduces manual pulling effort

• Provides smooth, controlled door operation

• External sprocket and roller-chain drive

• Includes #41 roller chain

• Includes 26 ft hand chain

• Includes chain keeper

• Includes 1/4" shaft key

• Suitable for commercial and industrial doors

• Ideal for new installations, repairs, and operator conversions

4:1 Gear Reduction

The integrated:

4:1 Mechanical Reduction

provides mechanical advantage between the hand chain and door shaft.

This makes a properly balanced commercial door easier to:

• Open

• Close

• Position

• Operate from floor level

The reduced gearing is particularly useful on larger commercial doors where direct-chain operation would require greater manual effort.

Wall-Mount Design

Unlike a chain hoist mounted directly on the torsion shaft, this configuration mounts the primary hoist mechanism to the wall or supporting structure.

A sprocket installed on the door shaft connects to the hoist through #41 roller chain.

Typical arrangement:

Hand Chain → Gear-Reduced Hoist → #41 Roller Chain → Shaft Sprocket → Door Shaft

Proper sprocket alignment and mounting are important for smooth operation and long component life.

1" Shaft Application

Designed for compatible door systems using a:

1" Shaft

Verify actual shaft diameter and keyway configuration before ordering.

The shaft must be compatible with the supplied sprocket and key arrangement.

Complete Manual Hoist Kit

The commonly supplied 2000R-1 configuration includes:

• Wall-mount 4:1 chain hoist

• Heavy-duty shaft sprocket

• 3 ft of #41 roller chain

• 26 ft of galvanized hand chain

• Chain keeper

• 1/4" shaft key

• Installation/set-screw hardware as supplied

Actual kit contents should be checked against the package supplied.

26-Foot Hand Chain

The standard system includes approximately:

26 ft of Hand Chain

This allows manual operation from floor level on many common commercial installations.

For unusually tall doors, additional hand chain may be required.

Chain Keeper

A chain keeper provides a convenient location to secure the hand chain when the door is not being operated.

Benefits include:

• Keeps chain organized

• Helps prevent chain from lying on the floor

• Reduces interference with the door opening

• Provides a consistent storage location

Common Door Applications

Suitable for compatible:

• Rolling steel doors

• Coiling doors

• Commercial overhead doors

• Vertical-lift doors

• High-lift doors

• Warehouse doors

• Loading-area doors

• Storage facility doors

• Industrial doors

Compatibility depends on door design, balance, shaft arrangement, and installation requirements.

Typical Applications

• Warehouses

• Distribution centers

• Storage facilities

• Commercial garages

• Loading docks

• Service shops

• Manufacturing facilities

• Agricultural buildings

• Industrial facilities

• Commercial overhead-door installations
