Small Tonnage Hydraulic Hollow Jack


Product Details


The oil cylinder, front and rear end covers, front and rear sealing plates and through-core sleeves of this series of hydraulic hollow jacks are connected by thread to form a whole, and are supported on the anchor plate of the working anchor through the limit plate to form a "moving body". The piston of the hydraulic hollow jack and the tool anchor supported on it form a group of "movement feeders". When the hydraulic oil pushes the "moving body" to move to the right, it can be stretched; when the hydraulic oil pushes the "moving body" to move to the left , that is, the piston returns after the tension is completed.


Advantage

1. Small size, light weight, easy to operate.

2. 25 ton hydraulic jack can be equipped with ZB2-500H electric hydraulic oil pump.
