grab-crane-garbage-disposal

The overhead crane for garbage disposal is with a garbage grab, which is an import equipment in city waste incineration plant. Overhead crane for garbage disposal is installed over the garbage pit for garbage charging, transport, mixing and weighing. This garbage disposal crane can be manual, semi-auto and fully auto type, carrying out automatic grabbing, automatic repeat feeding, automatic repeat dumping, and automatic parking.


Manual Type:
Operator control the crane with the linkage console.
Semi-Auto Type:
The grab operation is manual control, and the auto controlled part includes the moving to charging port, weighing and charging.
Fully-Auto Type:
Once the crane receiving the charging signal from the charge port, the crane starts to do every move automatically, moving to the garbage, lower the grab, grabbing the waste, lifting the waste, moving to the charging port, weighing, charging, and returning the position. It will repeat the same motion automatically.

Basic Operation:
1. Feeding. Grab and feed Fermented garbage into waste incinerator.
2. Lifting and transport. Lift and transport the waste near the discharge door to avoid blocking the discharge door. Control the quantity of garbage in the waste pit to keep the inventory within 3~5d.
3. Mixing. Mix the garbage to extract water content and shorten the fermentation time, as well as keep safe of incineration.
4. Fetching. Fetch non-flammable objects in the pit.
5. Weighing. Weigh the garbage before being dump into the incinerator.

Boat and Yacht Handling Crane / Weihua Crane

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.


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.

boat-handling-crane

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.

yacht-crane

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.


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.

ship-building-gantry-crane

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 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.

Derrick-crane

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.
