Introduction

●	Body connected by automatic welding process, avoiding oil leakage. Greatly-improved overall mechanical strength and unbalance loading proof capability.
●	High quality steel base and newly-designed hydraulic circuit formed through one-time processing in the processing center, ensuring the consistency of quality.
●	Fewer oil leakage problems due to seal problem, longer service life and convenient repair and maintenance.
●	Note: 2 ~ 20 tonnes jack stands can pass the dynamic overload test with a load 1.5 times the rated value; 32 tonnes and 50 tonnes jack stands can pass the dynamic overload test with a load 1.25 times the rated value.
