Characteristics of marine crane
1. Full hydraulic transmission, mechanical and electrical dual-use, safe and reliable work, high efficiency, low labor intensity;
2. Each hydraulic system is equipped with balance valve and hydraulic lock, which has higher safety and reliability;
3. The hoisting winch adopts normally closed hydraulic braking, single hook with high and low speed neutral gear and automatic control, with high hoisting efficiency;
4. The boom and important structural parts are made of low alloy steel plate to reduce the dead weight of marine crane and improve the performance of crane;
5. The slewing ring is made of 50 manganese forging material;
6. The boom is cold formed with 8-prism structure to give full play to the mechanical properties of the material;
7. The boom is retractable by hydraulic cylinder, which is more safe and reliable;
8. The night light is added to extend the working time;
9. Front and rear cab, negative arm and three-phase electric operation can be selected;
