Coke Oven Gate Lifting Equipment
Door Lifting
Power Winch
Control matters more than speed when lifting heavy Coke Oven doors. This Power Winch uses a high-ratio Worm Reducer Gearbox to multiply torque and keep the lift slow and steady. Powered by a robust 5-7.5 HP motor, it offers a lifting capacity of up to 5 tons.

What is a door lifting power winch?
A door lifting power winch is an electric winch that raises and lowers heavy coke oven doors on the battery bench. It is built for controlled lifting rather than speed: a 5 to 7.5 HP motor drives a worm reducer gearbox, whose high reduction ratio multiplies torque and keeps the door moving at a slow, steady rate.
The output shaft turns a grooved steel drum that winds the wire rope at about 2 to 4 metres per minute. Lifting capacity is 2.5 to 5 tons, which covers most standard coke oven doors, depending on battery height and door weight. Besides oven doors, the winch lifts isolation dampers in power plants and steel mills and serves maintenance bays without an overhead crane.
Precision Lifting for Critical Operations
The Manual Tools Company Door Lifting Power Winch is designed specifically for the vertical lifting of heavy industrial doors, particularly in Coke Oven Batteries. Unlike standard construction winches, this unit prioritizes steady, controlled movement over speed.
The core advantage lies in its Worm Reducer Gearbox. A worm drive reaches a high reduction ratio in a single compact stage, so a modest 5 to 7.5 HP motor produces the torque needed to raise a 5 ton door, and the lift stays slow and even rather than jerking the rope.

Safe Lifting Cycle
-
Step 01
Drive Activation
The 5-7.5 HP electric motor is engaged. Power is transmitted through a coupling to the input shaft of the Worm Gearbox.
-
Step 02
Torque Multiplication
The worm shaft drives the worm wheel. This reduces speed significantly while multiplying lifting torque, ensuring a smooth, non-jerky lift.
-
Step 03
Vertical Lift
The output shaft rotates the grooved drum, winding the steel wire rope. The load (Coke Oven Door) is lifted vertically to the desired height.
Coke Oven Doors
The primary application. Used on the bench for lifting and positioning heavy oven doors during charging.
Heavy Dampers
Used in power plants and steel mills to vertically lift heavy isolation dampers in flue gas ducts.
Maintenance Bays
General purpose vertical lifting for equipment maintenance where overhead cranes are not available.
Critical Check: Inspect the Wire Rope weekly. Look for broken strands or "bird-caging" near the drum attachment point.
Lubrication & Care
- Gearbox: Maintain oil level (SAE-90/140). Worm gears generate heat, so oil quality is vital.
- Wire Rope: Apply heavy lubricant/grease to prevent corrosion from coke oven fumes.
- Drum Bushings: Grease nipples on the drum shaft monthly.
Mechanical Inspection
- Inspect foundation bolts. Vibration can loosen them over time.
- Verify the limit switch functionality to prevent over-winding.
Why is a Worm Gearbox used instead of Helical?
A worm drive reaches a high reduction ratio in one compact stage, so a smaller motor delivers the torque a heavy door needs, and the lift stays slow and even.
What is the lifting speed?
These are designed for torque, not speed. The lifting speed is generally slow and controlled (approx. 2-4 meters/minute) to ensure safety.
What capacity do I need for a Coke Oven?
Standard Coke Oven doors usually require the 2.5 Ton to 5 Ton range, depending on the battery height and door weight.
Is the wire rope included?
Yes, a standard length is included, but we can customize the rope length and diameter based on your lifting height.
