Suitable for lifting and transport of flat steel plate(H type,I type,T-type,L-shaped steel,etc.)and structural iron(horizontal)hanging clamp, shaped steel.
Alock mechanism spring-tightening,event ata no load condition,clamps grip securely.
Mechanism gripping force is increased more strongly in proportion to the lifting load.
By the high-frequency hardening,cam distinguished durable die forging of special alloy steel.
