Bridge Erecting Crane, 1. Gantry crane on rail, 2. 5~100/20tons, 3. Heavy duty slipring motor, 4. CE/SGS/GOST ISO - details see: https://www.machineto.com/high-quailty-bridge-erecting-crane-for-project-construction-10196106

high quailty Bridge Erecting Crane for project construction

Specifications

1.Compact structure

2.Competitive price

3 It can move along the rail for a long distance.

The basic information of launching crane for bridge erecting:

According to the situation of present railway with less sub grade, more bridges and tunnels which connected too closely, our company learn from advantages of other launchers at home and abroad and close the gap, after amend the drawings many times, we design and make this new box-girder bridge launcher(double girder).

(1)Advantage:

Low height, narrow width, light weight and compact structure. The whole set can pass through the tunnel; what’s more, it can feed girder and erect girder in tunnel.

The weight of the maximal part is no more than 6.6t and the length is no more than 10m which can meet the vehicle transportation rules

To meet the requirement of the limit of present railway, it can work under the condition of multiple tracks.

The symmetrical design of main girder, and to reserve the hole of bolts to erect girder bidirectional and shift span for erecting

Auxiliary trolley and upside-down charging gantry are added, and it has quite complete function which can lay track. It can erect the girder of highway after modification.

It can move a long distance on the rail with self- power

Compact structure, easy to install and maintain for users. It only needs to disassemble partially when transfer site by train, the upside-down charging gantry can fold and pack by itself without a hoisting machine.

(3)Structure

Front outrigger

It is about 8t, and mainly completes the function, such as via whole, erect girder and lay rail act.

Main girder

Main bearing institution, and suspend girder for trolley

Auxiliary trolley

To achieve the hoisting of track panel and small tonnage object

Suspending girder trolley

Two storey.the down storey run longitudinally

The upper one traverse.

Middle outrigger

To support main girder and suspending girder trolley

Rear outrigger

To support the rear end of main girder

Electrical equipment

About 150kw, direct every act by remote control

girder transporter

To transport and feed girder

hydraulic pressure system

Front , middle and rear outrigger has their own

hydraulic pressure system, control separately

(4) Excellent After-Service

One year warranty for whole machines.

Low charge for continue maintenance when warranty is expired.
