Cantilever retractable cable Luo - group or chain with something

Hydraulic cranes and other off-road truck cranes and boom , boom box- type structure strength . To use. Internal cantilever , hydraulic cylinders and cantilever retractable cable Luo - group or chain to have a combination of telescopic mechanism . Cantilever retractable cable Luo - group or chain with something , retractable Air lift table telescopic boom cylinder use , so that after the boom is telescopic . Typically , 2 ? 6 section telescopic hydraulic , 2 , 3 , 4 and sequential turn retractable telescopic manner scalable layers while simultaneously stretching mode . In addition, the simple way retractable pin mechanism sky . Simple sky pin mechanism , usually in different ways , a book each sliding inside a hydraulic cylinder cantilever boom fixing pin , while the telescopic boom so that the lock sequence method .
Most of the box Hand fixed lift table structure cantilever , the cantilever tip of the cantilever is extended. Grants can arm mounting . Auxiliary boom installed , orientation and subsidies if the mounting angle boom boom boom of less than 45 ° is necessary . Raise performance, and subsidies boom boom tilt angle mounting angle separately. Link cantilever equipped with a coarse stuff , subsidies cantilever mounting angle (tilt angle ) and the longitudinal direction of the cantilever within 5 ~ 45 ° hydraulic cylinders , etc. can be set freely .
