Weihua Container Handling Crane for River Port

Recently, the Luohe Port, a river port, has officially opened, which marks the beginning of a new chapter in the development of shipping. As a leading company in the lifting industry, Weihua has provided 6 container handling cranes to the Luohe Port project.

In December 2011, the construction of Luohe Port began. The Luohe River Port re-construction project includes the Luohe Port project and the channel project. It has a designed annual throughput of 4.6 million tons. The channel project is designed according to the four-level channel standard and can pass 500-ton ships with a total length of 13.5 km.

The cranes provided by Weihua mainly serves the loading and unloading of container, bulk cargo at dock yard. Among them, the rail mounted container gantry crane (referred to as RMG) is composed of a crane traveling mechanism, a gantry frame, a cable reel, a trolley and a special spreader for containers. It is a special lifting equipment for loading and unloading of international standard containers.

Advantages:

1. Variable frequency speed control system provides smooth acceleration and multiple operating speeds for smooth braking, with features of simple operation and accurate positioning, which greatly reduced the maintenance cost of the crane.

2. Mobile cab runs synchronously with the trolley with wider operating field.

3. The 10t crane can quickly exchange the hook and the grab through the balance rope, which meet the needs of different working conditions.

4. The container crane spreader has three movement modes: front and rear tilting, left and right tilting and plane turning, which greatly improves the efficiency of container loading and unloading operations.

Weihua Ranks Top 500 of Chinese Private Manufacturing Enterprise

On August 22nd, the 2019 China Private Enterprises Top 500 Summit hosted by the National Federation of Industry and Commerce and the Qinghai Provincial Government was held in Xining, Qinghai. The summit focuses on the national strategic deployment and promoting high-quality development. At the meeting, the list of 2019 Chinese Private Enterprises Top 500 was announced, and the China Top 500 Private Enterprise Stressed Research Analysis Report was released. Weihua Group Co., Ltd. ranks No. 395 in the top 500 manufacturing enterprises of China's private enterprises in 2019. Since the National Federation of Industry and Commerce announced the list of the top 500 private enterprises in China in 2011, Weihua Group has been in this list for 9 years.

As a leading crane manufacturer in China, Weihua Group has always been committed to the development of innovation, green, intelligence, custom and network, and cultivating high-profit, high value-added and high-tech intelligent equipment. Weihua has confidence to lead the crane industry to towards glory.

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;
