400 tons 700bar high pressure electric double acting hydraulic jack cylinder
1. Describe of hydraulic jack:
High pressure electric hydraulic jack is powered by ZB series of high pressure electric oil pump,the function for oil pressure rebound, overflow, it is designed a safe protect pressurizer, it can protect emergent over pressure, especial construction can protect jack. Hydraulic jack can bearpartial loading is 5% of rated pressure. High pressure alloy cylinder is very durable, especially in the larger project, it is easily to be operated and control. It can be used for lifting heavy machine,bridge project, hydraulic engineering, harbour construction and other equipment. It has large output,light weight, remote control and other advantages, it can match with our high pressure oil pump, it can reach jack, push, pull and extrusion and kinds of working.

4.Feature of hydraulic jack:
| 1. Warranty period: 2 years, without incorrect and artificial damage |
| 2. Our steel material is 42crmo steel, its hardness is stronger than 45# steel. After hot treatment, its hardness is HRC30-38. |
| 3. Our seal rings are importedfrom American Parker, the sealing working life longer 5-6 times than made in China, and it save muchtime to replace, improveworking efficiency. |
| 4. Welding copper on piston rod, more hard-wearing, don't damage cylinder |
| 5. Slippy surface, which make seal kit's life longer. |
