Small ton bridge erecting machine

Bridge Erecting Machine: 1) Reasonable design and fine manufacture 2) Low cost and compact structure

specification of  bridge erecting machine:

we can adjust the technical parameters to meet different clients’ requirements.

‘Keeping innovation and pursuing excellence’ are our critical concept. Warmly welcome every friend to our company.

The bridge girder erection machine, designed to solve the existing problem during bridge erection is a new-type bridging equipment which keeps the advantages of traditional bridge girder launcher home and abroad

(1)Main feature/advantages

1. Unique honeycomb-girder structure, low deflection and high stiffness

2. put boundary beam in place one time when it has a side load. without hanging landing leg in the air, safe and reliable

3. if the landing leg front and back is changed a little, it can erect the bridge in a reverse direction

4. The error of bridge girder erection is less than 5mm

5. Unique pin connection, firm and reliable, easy to install

6. A-type fracture surface, continuous girder with low center of gravity, convenient and reliable

(2)Main structure and function

1. Main longitudinal girder

Consist of several independent section girder, upper the girder there is a track for trolley with hoist to transporting girder longitudinally, underpart of the girder is landing leg

2. Trolley with hoist

Consist of trolley frame, winch, pulley block and wheel box

3. Connection framework

Connect two main longitudinal girders together with bolts and pins

4. Landing leg

Consists of leg bracket, outer sleeve, inner sleeve, hydro-cylinder, pin, wheelbox twisted seat and travelling wheel box

5. Lateral movement track

Take u-steel and steel plate or joist steel as foundation, on the surface of which the steel rail is laid as a track

6. Boundary girder pylons

Consist of hammock and slings for lifting loads,be used to erect boundary girder

7. Hydraulic system

Consist of hydraulic unit, multiple directional control valve, hydro-cylinder and oil-way, be mainly used to jack the machine

8. Electrical system

Be made up of motor, control cabinet and so on.

Trolley with hoist and main longitudinal girder are controlled respectively by their own control cabinet.
