New HOWO TX380 6x4 12T Flatbed Dropside Capacity Cargo Transporting Truck Straight Arm Boom Crane Trucks for Sale

Crane truck, also known as truck mounted lifting and transportation vehicle, is a device that uses hydraulic lifting and telescopic systems to lift, rotate, and lift goods. It is usually installed on cargo trucks. It generally consists of a truck chassis, cargo compartment, power take-off, and crane.

According to the type of crane, it is divided into straight arm type and folding arm type. According to tonnage, it is divided into 2 tons, 3.2 tons, 5 tons, 6.3 tons, 8 tons, 10 tons, 12 tons, 16 tons, and 20 tons.

1. Understand the size of the lifted cargo, find the distance from the center of the cargo to the center of the crane column, and check the lifting capacity parameters of the crane based on the distance.
2. The lifting capacity (torque) of the crane is fixed, and the larger the working radius of the crane. The lighter the lifted cargo, the smaller the working radius, and the heavier the lifted cargo. (The working radius refers to the horizontal distance from the center of the torque to the hook.)
3. Considering the lifting capacity of the crane and the load-bearing capacity of the chassis, the larger the beam, the better. If the crane is larger and the chassis is smaller, it will cause deformation and fracture of the beam. A smaller chassis reduces the power of the engine, which affects the lifting capacity of the crane.
