The company's large-tonnage electric hydraulic jacks, double circuit, hydraulic return, in large projects jacks, long proven, is easy to operate and control the electric hydraulic jacks, hydraulic lock hollow jack product installation, with packing function, standard with pressure relief valve to prevent overload, it can protect the electric jack will not be damaged due to overload, facilitate safe operation. Connection to the device, using high-pressure hose and nipple connection, has the advantage of quick installation and removal, and to overcome the shortcomings of the traditional oil spill quick connectors thin self-locking hydraulic jack, with a flow rate, the advantages of rapid prototyping. Electric jack is mainly used for hydraulic lifting and removal operations electricity, construction, machinery manufacturing, mining, railway bridges, shipbuilding and other industries and other equipment installed. (1) double the oil thin jack, return speed, high work efficiency. (2) applies to top pressure or anti-pull effect. (3) outer thread and a plunger thread and base holes for easy installation. (4) movable saddle, work to protect the plunger. (5) Internal safety valve prevents accidental overload. (6) dust ring to reduce pollution and extend the service life of the hydraulic cylinder manual hydraulic jack, Lu Hydraulic (certified), Nujiang jack provided by the Texas Lu of the hydraulic machinery plant.
