Made of high-quality steel to ensure rated load tonnage and safe use Ultra-low design, wide range of models, can lift cars with lower chassis Double-pump hydraulic lifting structure, fast lifting The special protection structure of safety valve is added. When the use exceeds 1.15 times of the rated deadweight tonnage, the safety valve will be opened, and the load-bearing boom will no longer rise, ensuring the safety of use. Using low temperature hydraulic oil, suitable temperature for work: minus 30 degrees to 60 degrees Minimum height 80mm Maximum height 375mm
