Double Girder Semi-Gantry Crane / Weihua Crane

Gantry crane is a special kind of overhead crane. This double girder semi-gantry crane only has one side support leg, while the other side is mostly supported by walls of workshop/warehouse.

The double girder semi-gantry crane is mainly applied to lift and convey stuff outdoors. The A type supporting legs under the main girder runs directly on the ground track.

Girder Structure:

1. Truss girder:

The truss girder is welded of angle steel or I type steel with the advantage of low cost, light weight, better wind resistance, but because of more welding point, large deflection, small stiffness, lower reliability, the truss type gantry crane is suitable for the fields with lower safety requirements and smaller lifting weight.

2. Box girder:

The box structure is welded of steel plate with features of high security, big stiffness, which is generally applied to the operation of large tonnage stuff, while the box girder has the shortcomings of high cost, big self weight, and poor wind resistance.

3. Box double girder:

Double girder semi-gantry crane have the features of big lifting capacity, big span, good overall stability, various types, but the self-weight is larger than the other single girder gantry crane with the same lifting capacity.

Safety Protection:

1. Overload limiter;

2. Polyurethane rubber buffer, long service life and impact resistance;

3. Crane travelling limit switch;

4. Loss pressure protection, fault phase protection;

5. Emergency stop system;

6. Lifting height limiter;

Rubber Tire Track Laying Crane

The rubber tire track laying crane is more advanced than the traditional track-laying technology. It can be used to lift the tracks with two sets of cranes and carry the tracks into the tunnel for track laying. At the same time, it can be also used to lifting concrete tanks and with casting function.

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

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

The advanced track laying method: the tire-type track laying crane has the functions of laying track and pouring concrete, and 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.

32t Gantry Crane / Weihua Crane

The ME32+3t-30m A5 gantry crane is a large lifting gantry crane designed and manufactured for the People's Liberation Army. It is mainly used for underground construction and lifting work of equipment and personnel.

32+3t-30m A5 gantry crane

1. The trolley hoisting mechanism adopts double mechanism arrangement to increase the capacity of the rope and safety;

2. The hoisting mechanism adopts redundant design with height display and it has protection functions in case of broken shaft, broken rope, over speed, overload;

3. The gantry structure adopts lightweight design and finite element analysis to make the structure more optimized and reasonable, and its own weight is light, which reduces the wheel pressure;

4. Variable span, suitable for different site conditions;

5. Overall processing of crane and trolley with high assembly precision;

6. The components are durable and maintenance-free, equipped with hardened surface reducer, welding reel, rolling pulley and forged wheel;

7. Quick on-site installation and disassembly;

8. The whole machine adopts frequency conversion and PLC control technology, which has stable lifting operation, small impact and low noise;

9. The overall design of the crane is a perfect combination of CTS system and mechanical design, with stable operation;

10. The whole machine is equipped with electrical intelligent anti-sway function, which greatly improves the production efficiency of the whole machine and prolongs the service life;

11. With intelligent monitoring system, monitor and record the operating parameters of the crane;

12. Equipped with manual and button control, use the upper and lower software limit to decelerate and stop, and use the touch screen to adjust the lift height.

Container Gantry Crane for Railway Freight Yard / Weihua Crane

This gantry crane is for container handling used at railway freight yard. With the features of strong U-type gantry structure, double cantilever with rods, and light weight, this railway gantry crane has enough span and space for container handling with a 360° rotating spreader.

gantry crane is for container handling

Electrical Control System:

1. Digital frequency conversion and PCL control;

2. High Precision Sensor Data Acquisition Technology;

3. Industrial computer data analysis and processing system.

Operation Flow:

1. The container handling instructions are sent from the central control room to the working crane.

2. The driver cabine receives the instructions.

3. The crane driver starts the loading and unloading operation by the linkage table touch screen.

4. Touch screen real-time displays the spreader, crane and trolley position.

5. The control system temporarily receive plug-in jobs, while it gives priority to the ongoing job, then perform the plug-in job after finishing the current job.

6. Precise container positioning technology.

Machine vision accurately identify the location of container keyhole and read the container number, then intelligent control system adjust the spreader position and deflection angle to realize accuracy locking and precision container stacking.

7. Linkage table touch screen real-time displays the spreader, crane and trolley position.

8. This crane is equipped with PDS system, if the crane position does not correspond to the indication position from the PDS system, the crane does not execute the command, and sends out the alarm information. After the driver moves the crane to the system indication position, the crane continues to execute the handling command.

9. Programmed path planning and obstacle avoidance technology for optimizing path and obstacle avoidance.

10. The use of infrared space scanning carry out real-time scanning of yard container storage situation, and updating yard stacking 3d database. Spreader is controlled by intelligent program to run along the optimal path for intelligent obstacle avoidance to ensure safe working.

11. The central control room receives the completion information feedback of the crane and sends it to the database.
