500 ton hydraulic jack for load test

1. Describe:
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 bear partial 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.


2. Features:
Double acting design can highly improve the convenience.
Built-in safe valve can protect jack when over loading.
Cylinder can bear Max loading when Max stroke.
High quality seal ring make the jack's life more long, no oil leakage.

3. Technology data:
4.Application:
Our hydraulic jacks have been widely used for industrial field, such as steel plant, cement industry, chemical and refinery, bridge, railway, highway, hydropower station, ship repair, building, construction and maintenance.
