RMG Crane for Steel Track Handling

The RMG Crane for Steel Track Handling can be used for handling of steel pipe, steel sheet, steel plate or steel track with electromagnetic sling or clamp sling. During the hoisting operation of large projects for big projects, multiple cranes are usually applied together to hoist the same object through wireless linkage. It is not only safe and reliable, but also effectively guarantee the orderly progress of the task. The linkage cranes also greatly improves the lifting capacity and working efficiency, reduce the use and maintenance costs.

 

RMG Crane for Steel Track Handling

 

During hoisting operation, usually 2 or more cranes are used together to lift a same big object (oversize and overweight). This requires several cranes to have coordinated action and maintain synchronization during lifting, running and braking. In the project below, 4 RMG cranes are employed to handle steel tracks at railway freight yard.

 

 

Lifting Weight: 10t+10t

Steel Track Length: 100m

Site: Xi’an Railway Bureau, China

Way of Working: 4 cranes linkage operation

Sling: Hang beam with clamps

 

The 4 RMG cranes for Xi'an Railway Bureau adopts Siemens 1500PLC control system and Schneider ATV71 inverter. It realizes centralized control and sub-control by multi-machine wireless linkage control, making 4 cranes as a group, to lift a single 100-meter-long high-speed rail track.

 

 

Features:

1. The cranes can be controlled by the main console and the remote control, as well as operated separately in the cab.

2. When any crane fails, other cranes will stop working automatically

3. The control system has sound and light alarm to remind, diagnose, monitor, troubleshoot and shorten the maintenance time.

4. Electric control system also has a dedicated database for real-time recording of equipment operating conditions, which also can be used to calculate lifting mechanism cumulative overload times in safety work cycle.

5. Crane drive system uses absolute encoder to limit the travel error within 150mm for cranes' synchronous operation within 300m distance.

6. Trolley simultaneous travel uses Gray bus memory positioning, which limits the error ± 3mm in 20m traveling distance.

1. Seal up bulk materials.

2. Transport routines can be very long and bent.

3. It can enhance the transport inclination angle.

4. No off-tracking happens.

5. Conveying materials in two directions.

 

 

Structure:

1. Common discharge port

2. Charging port

3. Transition section of materials receiving

4. Special tubules tape

5. Transition section of materials unloading

6. Transmission Roller

 

 

Working:

After receiving the materials from the transition section, the conveyor belt will be rolled up into round tube shape gradually and the materials are sealed and conveyed. At the discharging section, the tube is unfolded gradually and the materials are discharged.

Portal Crane, Weihua Crane, Leading Crane Manufacturer

A portal crane is a crane with rotary boom and runs along the ground track. Portal crane allow ground vehicle or rail vehicle to run through its portal/gantry, which make enough working space for on-ground vehicles transport.

 

portal crane

 

Weihua Portal Crane Can be:

1. Port Portal Crane: This crane is equipped with a replaceable hook, grab and other spreader, as well as bucket, funnel or belt conveyor for material handling.

2. Ship Construction Portal Crane: For the lifting work at shipyard with a large lifting capacity and lifting height. Usually 2 or more lifting hooks are fitted on this crane. The lifting weight of the main hook vary with the range of work. The working speed is generally slower than that of port portal crane.

3. Container Portal Crane: Used for container handling and stacking at container freight yard.

 

 

Features of Weihua Portal Crane:

1. Spreader: grab or hook, good applicability;

2. 4-bar linkage boom, precise luffing. The 4 bar linkage mechanism is optimized by dynamics software. When luffing, the horizontal move of load is ensured, the transmission angle is increased and the pressure angle reduced, by which, the service lift of 4 bar linkage mechanism is increased.

3. 360° slewing, wide working area;

4. PCL control, AC frequency speed control, stable and reliable operation;

5. Remote control is available if necessary;

6. Enough protection devices, communication and lighting system;

7. Adopt electronic balance system to prevent overload of opening and closing mechanism and lifting mechanism;

8. The luffing mobile counterweight is adopted so that when operating, the upsetting moment caused by load is minimized and the service lift of revolving support is increased.
