The classified truck-mounted crane trucks can be divided into two categories: one is a straight-arm truck crane truck, and the other is a folding-arm truck crane truck. In accordance with the chassis classification can be divided into Dongfeng truck lifting truck, Futian truck lifting truck, liberated truck lifting truck, Yuejin truck lifting truck. According to the classification of tonnage can be divided into 2.5 tons, 3.5 tons, 4 tons, 5 tons, 6.3 tons, 7 tons, 8 tons, 9 tons, 10 tons, 12 tons, 13 tons, 16 tons, 20 tons, 25 tons and more tonnage. According to the structure can be divided into two arms, three arms and four arms. According to the function points, it can be divided into full rotation and rack rotation.
Working range SQ2.5 tons two-arm crane (lift height 7.3 meters, working radius 5.38 meters)
SQ3.5 ton two-section straight arm crane (lifting height 7.3 meters, working radius 5.38 meters)
SQ3.5 ton three-section straight arm crane (lift height 9.5 meters, working radius 7.6 meters)
SQ4 tons three-arm crane (lift height 9.5 meters, working radius 7.6 meters)
SQ5 tons three-arm crane (lift height 9.9 meters, working radius 8 meters)
SQ6.3 tons three-arm crane (lifting height 11 meters, working radius 9 meters
SQ6.3 ton 4 section straight arm crane (lift height 13.5 meters, working radius 11.9 meters)
SQ7 tons three-arm crane (lift height 11 meters, working radius 9 meters)
SQ7 ton 4 section straight arm crane (lift height 13.7 meters, working radius 12.1 meters)
SQ8 ton 4 section straight arm crane (lift height 13.2 meters, working radius 11.5 meters)
SQ9 ton 4 section straight arm crane (lift height 15.3 meters, working radius 13.5 meters)
SQ10 tons three-arm crane (lifting height 11 meters, working radius 9.3 meters)
SQ10 ton 4 section straight arm crane (lift height 13.5 meters, working radius 12 meters)
SQ12 tons three-arm crane (lift height 13.6 meters, working radius of 11.8 meters)
SQ12 tons of 4 arm cranes (lift height 17 meters, working radius of 15.2 meters)
SQ16 ton 4 section straight arm crane (lift height 17 meters, working radius 15 meters)
Note 1): Understand the size of the lifting goods, find the distance from the center of the goods to the center of the crane column, and check the lifting capacity parameters of the crane according to the distance.
2): The lifting capacity (torque) of the crane is fixed and the working radius of the crane is larger. The lighter the goods that are hoisted, the smaller the working radius and the heavier the goods that are hoisted. (Work radius refers to the horizontal distance from the center of the moment to the hook.)
3) Considering the lifting capacity of the crane and the bearing capacity of the chassis size, the larger the beam is, the better the crane is. The larger the crane is, the smaller the chassis is, and it will deform and break the girder. The chassis is small, and the power of the engine is small, affecting the lifting capacity of the crane. So when we consider the 230mm beam, we choose the crane below 3 tons. When considering the 250mm beam, consider the crane below 6 tons. The 280mm beam can select cranes up to 8 tons. Like the rear eight and the first four chassis can consider less than 10 tons of crane.
