China 800 Ton Prestressed Hydraulic Lift Jack

800 ton prestressed hydraulic lift jack

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.
