Overview
 

With the expansion of cities and growthing of traffics, many big cities are suffering from "urban disease" - serious traffic pressure. To solve this problem, people start to build subways. It is comfortable, fast and convenient, and becoming an important way of travel in urban cities.

For the subway construction, the construction equipment, especially the cranes and shield excavators, are becoming more and more important. As a leading crane manufacturer, Weihua has rich experience and many project case of subway construction gantry crane.

The main role of subway construction crane is for slag handling during subway tunnel construction. This kind cranes are used for lifting the dregs/slag excavated by shield excavator to the ground or lifting other site material.

Features of Subway Construction Crane:

1. Variable span, improve crane adaptability. With the span-changed function of Min. step-length 100mm, this gantry crane is suitable for various working conditions.

2. Cantilever can be detachable, more flexible. The cantilever is detachable, also can preserve the cantilever interface which will be flexible for different working conditions.

3. Travels fast, high work level, high efficiency;

4. Long lifting distance;

5. Tilting spreader with automatically tipping. The subway construction crane is equipped special spreader and realize the interchange of dregs bucket and the hook.

6. Lightning protection system AND wind speed detection warning system.

7. Overturn hook realizes overturning the dregs at any position in the air. Overturning dregs system is controlled by hydraulic which makes it more stable.

8. The trolley is rotatable, which can transport slags from the front and side.

Features

Features of Rail Type Gantry Crane for Beam Hoisting:
1. With special spreader;
2. Two cranes, two trolley, and Max. lifting height: 30m;
3. The concrete beam is parallel to crane rail;
4. Max. wheel load is 22t while lifting 900t beam;
5. Carry out 90°steering on straight and horizontal rails;
6. 4 points hoisting, 3 points balancing to ensure wire rope balancing and accurate landing;
7. Trolley adopts hydraulic push pole to realize different beam hoisting to save cost;
8. Total 4 winch trolley, which realizes drive separately, 2-2 drive or 4 simultaneous drive.

For Beam Moving:
Gantry crane for beam moving is mainly used for passenger railroad construction for concrete beam moving. Users can use 2 gantry cranes (500t, 450t) or 1 gantry crane (1,000t, 900t) with 2 lifting points to handle beams. There are 2 type for crane traveling: tire type and rail type.

The crane traveling, steering and hoisting of tire type gantry crane are all driven by hydraulic, which can realize traveling straight, oblique and horizontal, etc. Features of tire type gantry crane: Strong adaptability, high working efficiency, small footprint, need no rails, etc. Thus it is widely used for high speed railway construction for beam lifting, moving and loading.

Rail mounted gantry crane for beam hoisting is usually for lifting railway beams within 1,000t, which is driven by generating units on it. This crane travels on rails with 2 directions: straight and horizontal.

Features of Rail Type Gantry Crane for Beam Moving:
1. With special spreader;
2. Two cranes, two trolley, and Max. lifting height: 12m;
3. The concrete beam is parallel to crane rail;
4. Max. wheel load is 22t while lifting 900t beam;
5. Carry out 90°steering on straight and horizontal rails;
6. 4 points hoisting, 3 points balancing to ensure wire rope balancing and accurate landing;
7. Trolley adopts hydraulic push pole to realize different beam hoisting to save cost;
8. Total 4 winch trolley, which realizes drive separately, 2-2 drive or 4 simultaneous drive.
