The truck crane is a self-propelled hoisting machine composed of a tire-type base car as a carrier with a lifting equipment working device and a control mechanism. It is a type of construction machinery with a wide range of uses. It is suitable for large-scale field construction projects, such as construction sites, construction roads, water conservancy projects, national defense fortifications, construction of road cuttings and other projects such as transportation and lifting.

1. The test bench is made of cold-rolled steel plate (with plastic spraying and anti-corrosion treatment), and has a bench-top structure and integrated control and push operation.

2. The electrical operation control is under-mounted, and the hydraulic station is placed in the main cabinet of the hydraulic table. The overall structure is compact and coordinated, the layout is beautiful and generous, and the practicability is strong, and it can be used for 4-6 people to experiment.

3. The all-metal structure of the hoisting machinery is reduced in proportion to the actual object. During the experiment, the hydraulic system is activated to simulate the operation of the machinery to work according to the experimental requirements. The extension and lowering boom of the crane is a three-level structure.

4. Hoisting machinery is manufactured according to the actual structure and reduced scale, which can truly reflect the actual working conditions of the machinery, so that students can deeply understand the structure and working principle of each part of the mechanism in the experiment.

5. Experimental control adopts manual control and automatic control.

6. The experimental parts adopt pressure-resistant hoses, and the pressure can reach 25Mpa. 7. With three-phase leakage protection, the output voltage is 380V/220V, the power supply will be cut off when the leakage current to the ground exceeds 30mA; the electrical control adopts DC 24V power supply, and with overvoltage protection to prevent misoperation from damaging the equipment.
