Crane training platform
The truck crane is a self-propelled hoisting machine composed of a tire-type basic vehicle as a carrier and a lifting equipment working device and a control mechanism. It is a machine with a wide range of uses in construction machinery. It is suitable for large-scale field construction projects, such as construction sites, construction roads, water conservancy projects, national defense fortifications, construction of cuttings and other projects, such as lifting, lifting and other operations.
1. The experimental bench is made of cold-rolled steel plate (and has been sprayed and treated with anti-corrosion), with a desktop 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, which can be used for 4-6 people to experiment.
3. The all-metal structure of the hoisting machinery is scaled down according to the actual object. During the experiment, the hydraulic system is activated to simulate the operation of the machinery according to the experimental requirements. The extension arm of the crane is a three-level structure.
4. The hoisting machinery is made according to the structure and scale of the real object, which can truly reflect the actual working conditions of its machinery, so that students can deeply understand the structure and working principle of each component of its mechanism in the experiment.
5. The experimental control adopts manual control and automatic control.
6. The experimental part adopts pressure-resistant rubber hose, and the pressure can reach 25Mpa.
7. With three-phase leakage protection, the output voltage is 380V/220V, and the power supply is cut off when the leakage current to the ground exceeds 30mA; the electrical control adopts DC 24V power supply, and has overvoltage protection to prevent misoperation from damaging the equipment.
