Abstract

The invention discloses a transmission vibration reducing structure of a crane lifter. The transmission vibration reducing structure comprises a lifter body, a dual-folding type lifting frame fixed on the lifter body, and a supporting table fixed at the upper end of the lifting frame; the lifting body is provided with a rolling wheel. The transmission vibration reducing structure is characterized in that the lifter body comprises a hydraulic cylinder used for providing power source, a first bottom plate and a second bottom plate; multiple vibration reducing devices are arranged between the first bottom plate and the second bottom plate, and each of the vibration reducing devices comprises a first cushion ring, a vibration reducing spring and a second cushion spring which are arranged in order; the first bottom plate and the second bottom plate are fixed together by crossing through the vibration reducing devices by a bolt. The transmission vibration reducing structure of the crane lifter is simple in structure, strong in practicability, convenient to lift, and good in vibration reducing effect, and the like.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a transmission shock-absorbing structure of a crane lifter. Background technique [0002] At present, the crane scissor lift is a special equipment for high-altitude operations with a wide range of uses. Its scissor-type mechanical structure makes the lifting platform have higher stability after lifting, and the wide working platform and higher carrying capacity make the range of high-altitude work larger and suitable for multiple people to work at the same time. It makes working at heights more efficient and safer. It is a widely used lifting equipment for aerial work. [0003] The lifting mechanism is made of high-strength manganese steel giant tube. Equipped with a safety protection device to prevent the elevator from being overloaded. Equipped with a safety protection valve to prevent the hydraulic pipeline from breaking. Equipped with emergency descending device in case of power f...
