1. Horizontal movement

HZQ30-80 bridge girder launcher

HZQ30-80 bridge girder launcher

a. As an important front part support of the bridge girder launcher, front support leg uses transverse movement gear box and transverse sliding rail to make the whole machine move transversely

b. As an important rear part support, middle support leg uses transverse movement gear box and transverse sliding rail to make the whole machine move transversely

c. Transverse moving mechanism at upper part of the lifting trolley can make the trolley move transversely along transverse sliding beam and rail

 

2. Install the boundary beam

The trolley lifts the girder to move transversely, distance between lifting steel wire and the bottom part of main girder should be about50mm

The whole machine moves transversely to put the boundary beam in the right place at a time. There is no need for the bridge girder launcher to move out of the abutment, quite safe, reliable and convenient.

3. Safety control mechanism

a. Electrical safety control

Leakage protection device for main power switch; launcher travelling emergency stop button; lifting travel limit(highest), launcher moving limit, trolley moving limit; lifting loader limiter; lifting trolley parking locking device; launcher clipping rail device

b. Electrical system protection device

Overload, overcurrent, short-circuit protection, monitoring indicator and interlocking device; overvoltage, undervoltage protection; mechanical, electrical interlocking institution (avoid misoperation)

Limit switch

Launcher moving limit, trolley moving limit, lifting travel limit (highest)

Overload

Lifting load limiter
