Rail Mounted Container Gantry Crane / Weihua Crane

Rail mounted container gantry crane (RMG crane) is mainly used to load, unload, move and stack containers in railway transship fields and large container storage yards. It is constituted by main girder, rigid and flexible outriggers, trolley travel mechanism, lifting mechanism, crane travel mechanism, electric system and operation cab.

This rail mounted container gantry crane can be 3 kinds based on operating type in storage yards: whose girders outreach at the direction of the single outrigger is called single cantilever crane and at the direction of the double outrigger is called double cantilever crane, and whose girders do not outreach is called non-cantilever crane. Users can choose different types depending on the different demands of yards, storage and transport ways of containers and vehicles (trucks or railway vehicles). 

Rail mounted container gantry crane

Features of Rail Mounted Container Gantry Crane:

1. Low lifting speed because of low lifting height. High crane traveling speed fits the requirement of the long-track containers storage yards' productivity. The spreader would go over the fourth/fifth container layer when the stack of containers is three/four layer and its lifting height depends on the requirements of storage yards 

2. The trolley traveling speed depends on the span and the outreaching distance of both sides of the bridge. In the case of the span and outreaching distance is short, smaller trolley traveling speed and the productivity is advisable; otherwise, the trolley traveling speed could be accordingly increased to meet productivity requirement.

3. When the span is over 40 meters, the crane mechanism travels in a high speed, and both sides of outriggers would deviate because of the drag on each side is different. So there is a stabilizer equipped on this crane and electric system would keep both sides of traveling mechanisms synchronous.

4. Electrical drive-control system adopts thyristor speed regulating drive AC or DC control system to meet the higher need and accomplish a better performance of speed regulating and control. Or it adopts conventional AC eddy current speed regulating control system and AC stator voltage and speed regulating drive control system.

An electric braking that equipped with thyristor speed regulating drive AC or DC control system or AC stator voltage and speed regulating drive control system is usually used as the electric control system of a high speed crane traveling mechanism. Conventional AC eddy current speed regulating drive control system which depends on the brakes to shut down traveling mechanisms should be avoided in order to prevent the huge impact to whole crane.

Grab Dredgers / Weihua Crane

Grab dredgers are used for dredging work in waterways, harbor pools and underwater infrastructure works. It is suitable for dredging mining mud, gravel, pebbles and cohesive soil, but not suitable for dredging fine sand.

Grab dredgers

Cross Digging:

The grab dredger is suitable for the cross digging. 5 anchor cables shall be arranged and length of the main anchor cable and tail anchor cable shall be 200m to 300m. Edge anchor cable should be set aside about 100m.

Downstream-Countercurrent Digging:

It prefers downstream digging compared with countercurrent digging. Countercurrent digging also can be adopted in case of low water flow rate or reciprocating water flows.

Grab volume: 18m3

Dredging depth: 50m in water, 10m above water

Grab dredger arm length: 30m

Working radius: 15-23.5m

Features of Grab Dredgers:

1. Visual Simulation;

2. Underwater visualization work;

3. GPS positioning, precise dredging control;

4. Consistent excavation depth;

5. Flat dig control to ensure the accuracy of 15cm flat dig.

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.

Yacht handling cranes

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.
