The invention discloses a small construction crane convenient to operate. The small construction crane convenient to operate comprises a crane body. Supporting columns are fixedly connected with the left side and the right side of the top of the crane body, and motors are fixedly connected with the tops of the supporting columns. According to the small construction crane convenient to operate, bymeans of the cooperation of an anti-collision plate contraction device and a servo motor, the effect that the bottom of the servo motor and the top of the anti-collision plate contraction device are fixedly connected, and therefore the anti-collision plate contraction device is controlled by the servo motor is achieved. in addition, a rotating block is fixedly connected with the inner wall of theleft side of the anti-collision plate contraction device, a rotating shaft is fixedly connected with the right side of the rotating block, then a winding drum is fixedly connected with the outer wallof the rotating shaft, an anti-collision plate body is wound around the outer wall of the winding drum, and therefore the object lifting protection can be conducted through the anti-collision plate body, and the situation that after an object makes contact with a wall, the damage is caused is avoided.
Description
technical field [0001] The invention relates to the technical field of cranes, in particular to an easy-to-operate small construction crane. Background technique [0002] Crane is also known as; Crane refers to the multi-action hoisting machinery that vertically lifts and horizontally carries heavy objects within a certain range. Also known as cranes, aerial cranes, cranes, and tire cranes, the main features are: the driving cab and the lifting control room are combined into one, and it is evolved from a crawler crane (crawler crane). The bracket part becomes a chassis with tires, which overcomes the shortcomings of crawler cranes (crawler cranes) that crawler shoes cause damage to the road surface. It belongs to material handling machinery. Bridge cranes are horizontally placed over workshops, warehouses and stockyards for material lifting. Lifting equipment. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The brid...
