Tube Belt Conveyor / Weihua Group

As a kind of environment-friendly continuous transport equipment, the circular tube belt conveyor is mainly used for transporting coal, colliery coal, coke, blending materials, sintered ore, mineral powder, petroleum coke, limestone, sand-gravel aggregate, acetylene sludge, humidifying dust, chemical fertilizer, salt, waste paper, phosphorus gypsum, sulfur-iron slag and all kinds of bulk materials. The circular tube belt conveyor has the same working principle with the ordinary belt conveyor; namely, make use of friction to move the conveyor belt and its materials. The most of components can be commonly used with the ordinary belt conveyor, however, the difference is that the conveyor belt shall be rolled up in the circular tube shape.

Performance Features:

1. It can seal and transport the bulk materials.

2. It can arrange the transport routines in the space warp way.

3. It can enhance the transport inclination angle.

4. There is no off-tracking phenomenon.

5. It can transport materials in two directions.

Principle and Structure of Circular Tube Belt Conveyor:

1. Common discharge port

2. Charging port

3. Transition section of materials receiving

4. Special tubulous tape

5. Transition section of materials unloading

6. Transmission Roller

circular tube belt conveyor

When the conveyor belt has received the materials from the transition section on its tail, the conveyor belt will be rolled up in the circular tube shape gradually, then, the circular tube tape will be applied to transport the materials in the sealed way, then, the conveyor belt will be unfolded gradually when the materials are transported to the head transition section until the materials are discharged.

Derrick Crane 330t / Weihua Crane / Weihua Group

A derrick crane is a lifting device usually composed of mast (frame or tower) and lifting arm. There are three or four lines connecting the mast to the lifting arm, which controls it goes up and down. To lift a load, a separate line runs under the lifting arm with a hook as the hoisting mechanism.

derrick crane

Derrick cranes are docking facilities mounted on vessels or dockside. Recently, Weihua made a 660t derrick crane for Jiangsu Jinghu Heavy Industry, China. This crane is employed to lift 22,000m3 LPG tanks, which consists of platform/base, lifting arm and A-frame mast. It is designed with 2 hooks with capacity 2*330t. The arm length is 70m with luffing 21.5-54m, mast diameter is 1.6m.

Features:

1. There are 4 driving system for hoisting mechanism, 2 driving system for luffing mechanism.

2. The entire derrick crane chassis adopt basin support on concrete platform, which can effectively ease the crane horizontal and vertical deformation.

3. Multi-layer winding line reel drum. Hoisting winding drum wrapped with 4 layers of wire rope, and luffing drum is wrapped with 5 layers of wire rope.

4. Complete frequency, lifting half load speed is 2 times of the full load speed.

5. Using inverter, encoder and a series of electronic control system to ensure the 4 lifting motors keep synchronous running.

Marine Deck Crane / Deck Crane / Weihua Crane

Marine deck cranes are designed for safe and effective loading and unloading of cargo on general cargo ships, container cargo ships, bulk carriers and other transport ships. Marine deck crane is suitable for bulk carrier, container vessel, engineering ships which are voyaging international or domestic.

Marine deck cranes

The hydraulic system of Weihua deck crane innovatively adopts a closed system instead of the open system, solving the problem of the lifting brake control, which is rare to see for deck cranes. After successfully applying the closed system of the deck crane, the hydraulic oil consumption has been reduced by more than half compared to the open system deck cranes, and the power consumption has also been greatly reduced. This is a major breakthrough in energy saving and environmental protection. This crane has obtain 6 national patents.

Features of Weihua Deck Crane: 

1. Built-in machine, electric, hydraulic, integrated system.

2. Fully hydraulic drive.

3. Self-diagnosis wave compensation system.

4. Luffing load horizontal movement technology.

5. Eight safety devices including torque limiter, etc.

6. Visible safety monitoring system.

Gantry Crane for Ship Building / Weihua Crane / Weihua Gantry Crane

The ship building gantry crane can be single girder gantry crane and double girder gantry crane. When it comes to large span and lifting weight, we suggest the single girder gantry crane for ship building which is more economy.

ship building gantry crane

The single girder gantry crane for ship building is mainly composed of steel gantry frame, upper trolley, lower trolley, trolley travelling mechanism, maintenance, lubrication, elevator and electric equipment. And there are rail clamp device (or wheel actuator), anchor device, lifting weight limiter system, wind speed and direction system, limit switch of each mechanism, and the other safety protection device for this crane. The deviation rectifying system can be equipped in case of very large span.

Weihua has rich experience on the manufacturing of gantry cranes for ship building with big lifting weight, lifting height and span.

Main Data of Gantry Crane for Ship Building:

1. Lifting weight: 10-200t;

2. Lifting height: 8-12m;

3. Standard span: 5-35m
