Description

Technical Field

[0001] The utility model relates to the technical field of lifting platforms, in particular to a vehicle-mounted lifting platform for maintenance. Background Art

[0002] The vehicle-mounted lift platform for maintenance is modified from a lift and a truck. It can improve the maneuverability of the lift platform and fix the lift platform on the truck bed, thereby realizing the lifting function of the vehicle-mounted lift platform. It is often used for maintenance operations at high altitudes.

[0003] Currently, the existing vehicle-mounted lifting platforms for maintenance often use scissor-type lifting frames to achieve the lifting of the platform. However, this type of lifting platform still has a certain height when the lifting frame is folded. When personnel carry heavy maintenance tools, it is more troublesome to enter the lifting platform.

[0004] Therefore, in view of the problem that it is troublesome for personnel to enter the lifting platform when carrying heavy maintenance tools, a maintenance vehicle-mounted lifting platform can be designed. By setting a motor, a threaded rod, a movable plate, and a lifting plate, the personnel carrying the tools first stand on the lifting plate, and then start the motor, so that the lifting plate can move upward. When the lifting plate moves to the top, the personnel can enter the interior of the lifting platform, avoiding the need for personnel to climb into the interior of the lifting platform when carrying heavy maintenance tools, thereby improving the comfort of the personnel. Utility Model Content
