                    QGX-C hoist limit switch for crane

1.Description

QGX series hoist limit switch is designed and manufactured with digesting the related information of overseas one and combining with the practical condition in China .
It is a safeguard applied for limiting the hoisting height of cranes. It operates with worm , worm wheel , cam and sensitive switch . It has the advantages of light weight , compact, reliable installation and long service life .It also can be assembled with height control meter through connecting with encoder, which forms electromechanical dual fail-safe .

Operation principle

The hoist limit switch is generally installed on the cover of reel's bearing pedestal and the worm is connected with barrel arbor . The reel rotates with worm wheel and worm . When the rim of cam contacts with the contact of sensitive swith ,the sensitive swith operates cutting off
the power for lifting and lowering . The hook block shall stop in the limiting positiom .Lifting and lowering has two protections respectively .

QGX-C hoist limit switch for crane :
All kinds of crane, elevator, lifting stage, golf, bowling, etc have shift mechanical equipment, can effectively prevent the summit, derailed, falls wait for equipment and staff accident, which is widely used.
