Electrolytic multifunctional cranes are auxiliary equipment for large-scale pre-baked anodic aluminum electrolytic production. Multifunction Crane for Electrolytic Aluminum can meet the environmental requirements and process requirements of high temperature molten salt, high current, strong magnetic field, dusty working site, and complete the process of prebaked anode aluminum operating.

Multifunctional Crane for Electrolytic Aluminum is composed of feeding mechanism, slagging mechanism, the anode replace mechanism, shelling mechanism and aluminium discharging mechanism.

Electrolytic multifunctional cranes

Electrolytic aluminum overhead crane is a large process equipment for pre-baked aluminum electrolysis, which is mainly used to complete the following task:

1. Shell: Open the electrolyte crust;

2. Replace the anode: pull out the residual pole, put on a new anode;

3. Slag: pull out the residual pole, remove blocks in the molten aluminum;

4. Feeding: add alumina powder and covering material to the groove;

5. Lifting: lifting bus frame.

Yacht handling cranes, also known as boat handlers. It is widely used in water sports games, yacht clubs, navigation, shipping and learning, etc. It can transport different tonnage (32 tons - 1000 tons) of boats or yachts from the shore dock for on-shore maintenance, repair or launching of new vessels.

Yacht handling cranes

The boat and yacht handling crane includes the following items: main structure, traveling wheel block, hoisting mechanism, steering mechanism, hydraulic transmission system and electric control system. The main structure is N type, which can transfer the boat/yacht with height surpass crane's height.

According to different requirements of our customers, the boat handling crane can handle different tonnage boats or yachts (10T-800T) from the shore side, it can be used for the maintenance on the shore side or can put the new boat into the water. This yacht handling crane has soft and firm belt to lift the boat and yacht so that it will never hurt the surface. This crane also can put the boat in sequence quickly with small gap between each two boat.

Features of Yacht Handling Crane:

1. For the crane traveling, this crane can move in diagonal direction, this boat and yacht handling crane also can steer in 90 degree and put the boat in any designated position according to requirements.

2. This crane can be adjusted the width of the main girder according to the boat in case to handling different side boat.

3. This yacht handling crane is of low expense, high performance, easy to operate and maintenance and so on.

4. Low cost on the daily operation, it adopts the soft and firm belt to ensure there is no harm to the boat when hoisting.

5. This boat crane can make the boat in order quickly; it also can adjust the gap between each boat according to different condition.

Gantry Crane for Ship Building / Weihua 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

Derrick Crane / Weihua Crane

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.
