Problems solved by technology

[0002] The existing vehicle-mounted lifting platform generally adopts a scissor-type lifting platform. The working platform can only be lifted up and down, and the working range is small. The position is required, which affects the scope of use of the lifting platform, such as the announcement number: CN 202063689U, "Scissor Lifting Platform Electric Vehicle", what this patent uses is a scissor lifting platform, and its working range is limited to up and down lifting, which affects the working range
There is also a more advanced telescopic cantilever lifting platform carried by gasoline vehicles, but each section of the telescopic cantilever needs a hydraulic cylinder to drive it to expand and contract, so the entire telescopic cantilever is very heavy. , so the cost is high
Gasoline vehicle-mounted telescopic cantilever lifting platforms are mostly used for high-altitude maintenance of street lamp repairs, power circuits, and telecommunication circuits, so the utilization rate is very limited. Not economical, it cannot be promoted and used in towns and cities in our country
In addition, the existing telescopic cantilever lifting platform for gasoline vehicles is very heavy because of its telescopic cantilever, so the adjustment of the left and right angles of the telescopic cantilever is very limited, and it cannot be rotated 360 degrees, which affects the working space of the platform.
The exhaust gas emitted by gasoline vehicles will also pollute the urban air.

Abstract

The invention relates to a telescopic cantilever lifting platform car and belongs to the technical field of lifting platforms. The telescopic cantilever lifting platform car comprises a running vehicle, a telescopic cantilever and a working platform arranged at the top end of the telescopic cantilever. The telescopic cantilever lifting platform car is characterized in that a telescopic cantilever telescoping mechanism is arranged on the telescopic cantilever and is composed of a bottom cantilever at the bottom and more than one telescopic cantilever section mounted in the bottom cantilever, one upper telescopic cantilever section is sleeved with one lower adjacent r telescopic cantilever section, a hydraulic cylinder is mounted between the bottom cantilever and the bottom of the first telescopic cantilever section, more than one chain wheel or fixed pulley is fixedly mounted at the top end of each of the rest telescopic cantilever sections except for the uppermost telescopic cantilever section, one end of a chain or rope mounted on the chain wheels or the fixed pulleys is fixed to the bottom cantilever or the adjacent lower telescopic cantilever section, and the other end of the same is fixed to the bottom end of the adjacent upper telescopic cantilever section. The telescopic cantilever is lightweight; the running vehicle matched with the telescopic cantilever is reduced in weight, thereby being low in cost.
