Description

Technical Field

[0001] This utility model relates to the field of lifting technology, specifically to a lifting platform for lifting large equipment. Background Technology

[0002] A lifting platform, also known as a lifting work platform, is a multi-functional lifting mechanical equipment. It can be divided into fixed and mobile types, guide rail type, articulated boom type, scissor type, chain type, loading and unloading platform, etc. Scissor lifts with large wheels are suitable for outdoor operations in factories, workshops, and crane repair, while scissor lifts with small wheels are lightweight and have a beautiful appearance, often used in high-end indoor places such as municipal enterprises and hotel auditoriums.

[0003] As disclosed in the authorization announcement number CN212687510U, a dual-drive lifting platform includes a base box and a cable. Support columns are fixedly connected to both sides of the top of the base box, and pulleys are movably connected to the top of the support columns via a rotating shaft.

[0004] Although it incorporates a base box, cable, support column, pulley, lifting platform, lifting ring, motor, drive shaft, take-up reel, electric telescopic rod, and support plate to construct a dual-drive lifting platform, the motor drives the drive shaft to rotate, which in turn drives the take-up reel to rotate. The take-up reel then tightens the cable, allowing the lifting platform to move up and down, forming a single-stage drive lifting platform. The electric telescopic rod then pushes the support plate to adjust its height. The combination of these two components achieves the purpose of dual-drive, solving the problem that single-stage lifting platforms cannot reach higher heights while meeting certain lifting stroke requirements, thus affecting high-altitude assembly operations.
