T Series Hydraulic Tank lifting device is a large-scale equipment specially designed for the national oil reserve project developed suitable steel giant silo tank inversion welding process engineering.This type of device is a two-stage single-acting hydraulic cylinder (hydraulic jacks) for VTOL work force or return required from back position, it can not use for horizontal work. Structured compact device, Safe and stable, easy to operate, load adjustable, quick installation, high synchronization accuracy.YT Series Hydraulic Tank lifting device is "dragged five" Oil supply: Each pump station connected to the hydraulic cylinder 5; thus avoiding excessive tubing traditional centralized oil brings,leakage points more than the disadvantages, to ensure that environmental pollution to a minimum.
