Rubber Tire Railway Laying Crane / China Leading Crane Manufacturer

 The rubber tire railway laying crane is different from the traditional track-laying method. It is more advanced technology, which uses 2 cranes to lift the rail tracks and carry the tracks into the tunnel for railway laying. At the same time, this crane can be also used to lifting concrete tanks and with casting function.

 

rubber tire railway laying crane

 

The Tel Aviv light ballastless track project is an important project in Israel. It is the largest government-licensed infrastructure construction project in Israel with the largest investment scale, complicated construction and large technical difficulty.

 

 

The traditional railway laying method: firstly lay a temporary track for the track laying machine and the concrete pouring car, and then lay the railway track by the railway laying machine; after the construction of the concrete pouring car completed, the temporary track is removed. So the process is complicated, a lot of equipment is used, and with long construction period.

 

 

The advanced railway laying method: the rubber tire railway laying crane has the functions of laying track and pouring concrete, and it does not need temporary track, requires less construction equipment, saves labor and time.

 

 

The whole foundation of the ballastless track can replace the loose gravel bed track, which has the advantages of good smoothness, high stability, long service life and less maintenance work. The train can run at speeds of more than 350km/h, which is the world's advanced track technology.

 

 

Features of Rubber Tire Railway Laying Crane:

1. Modular design, convenient transportation and installation.

2. The gantry lifting, variable pitch, steering, and concrete tank lifting are all controlled by electro-hydraulic control, stepless speed regulation, and each action can be performed separately or in combination.

3. The concrete tank clamping mechanism is equipped with high-quality synchronous valve and safety valve, and the synchronization accuracy is over 98%.

4. Walking frequency control, all-wheel drive, high stability, strong ground adaptability.

5. One-button to control all-wheel steering and rail change, steering mechanical limit, straight travel lock and other functions, practical and efficient.

6. Pendant and remote control, interlocking functions, safe and reliable.
