Description

Technical Field

[0001] The utility model belongs to the technical field of winches, in particular to a winch for hoisting a tower crane. Background Art

[0002] The winch used for tower crane hoisting is mainly composed of components such as an electric motor, a reducer, a drum, a brake, a control system and a wire rope. Among them, the electric motor serves as the power source and is connected to the reducer through a coupling. The output shaft of the reducer is passed through the drum, and the wire rope is wound around the drum for lifting or lowering heavy objects. The brake is used to stop the operation of the winch when necessary to ensure safety.

[0003] For example, Chinese patent publication number CN221165763U discloses a tower crane hoist, comprising a hoist assembly with a protective mechanism mounted thereon; a movable assembly internally rotatably connected to a locking assembly; and a U-shaped fixed frame internally rotatably connected to an I-shaped reel driven by a drive motor and wound around the I-shaped reel. The utility model provides an arc-shaped clamping plate that can be clamped onto a barbed plate, preventing material at the bottom of the wire rope from falling if the drive motor is damaged. Furthermore, when the wire rope needs to be released from the I-shaped reel, an electric push rod is activated, which drives the U-shaped seat and the entire locking assembly to move, thereby disengaging the arc-shaped clamping plate from the barbed plate, allowing the wire rope to be released from the I-shaped reel.

[0004] The above patent has the following problems:

[0005] This patent has some drawbacks during use. For example, after prolonged use, the rope on the hoist may come into contact with various contaminants, such as mud, cement, and grease. If these contaminants adhere to the rope, they may increase friction between the rope and the hoist drum or other components, causing accelerated rope wear and even potential safety hazards such as rope breakage. In view of this, we propose a hoist for tower crane hoisting. Utility Model Content
