Description

Technical Field

[0001] The utility model relates to the technical field of winch mechanisms, in particular to a lightweight truck-mounted crane winch mechanism. Background Art

[0002] Truck-mounted cranes are mainly divided into two types according to their structural forms: straight-arm truck-mounted cranes and folding-arm truck-mounted cranes. Straight-arm truck-mounted cranes rely on a winch mechanism to complete lifting and can achieve vertical lifting of heavy objects.

[0003] However, when the wire rope of the existing truck crane winch mechanism is retracted or released, the wire rope wound in the reel does not change position when it is retracted or released, causing the goods being hoisted to shake when the wire rope is retracted or released, resulting in poor stability when hoisting the goods and posing a safety hazard. Secondly, the winch mechanism installed on the crane mechanical arm is exposed to the outside for a long time. After a long period of wind and rain, the wire rope is easily rusted and the drive motor is damaged. In view of the above problems, the inventor proposes a lightweight truck crane winch mechanism to solve the above problems. Utility Model Content

[0004] In order to solve the problem that when the wire rope of the existing truck crane winch mechanism is being retracted or released, the wire rope wound in the reel does not change position in the reel during reeling or releasing, causing the goods being hoisted to shake when the wire rope is retracted or released, resulting in poor stability when hoisting the goods and potential safety hazards; the purpose of the utility model is to provide a lightweight truck crane winch mechanism.
