Portal Crane, Weihua Crane, Leading Crane Manufacturer

A portal crane is a crane with rotary boom and runs along the ground track. Portal crane allow ground vehicle or rail vehicle to run through its portal/gantry, which make enough working space for on-ground vehicles transport.

 

portal crane

 

Weihua Portal Crane Can be:

1. Port Portal Crane: This crane is equipped with a replaceable hook, grab and other spreader, as well as bucket, funnel or belt conveyor for material handling.

2. Ship Construction Portal Crane: For the lifting work at shipyard with a large lifting capacity and lifting height. Usually 2 or more lifting hooks are fitted on this crane. The lifting weight of the main hook vary with the range of work. The working speed is generally slower than that of port portal crane.

3. Container Portal Crane: Used for container handling and stacking at container freight yard.

 

 

Features of Weihua Portal Crane:

1. Spreader: grab or hook, good applicability;

2. 4-bar linkage boom, precise luffing. The 4 bar linkage mechanism is optimized by dynamics software. When luffing, the horizontal move of load is ensured, the transmission angle is increased and the pressure angle reduced, by which, the service lift of 4 bar linkage mechanism is increased.

3. 360° slewing, wide working area;

4. PCL control, AC frequency speed control, stable and reliable operation;

5. Remote control is available if necessary;

6. Enough protection devices, communication and lighting system;

7. Adopt electronic balance system to prevent overload of opening and closing mechanism and lifting mechanism;

8. The luffing mobile counterweight is adopted so that when operating, the upsetting moment caused by load is minimized and the service lift of revolving support is increased.

Ship Unloading Machine

 1. Bridge Ship Unloader with Grab

This bridge type ship unloader with grab is a cutting-edge unloading equipment used at the wharf. It is a commonly seen machine in the bulk importing area at the wharf with the features of good maturity, reliability, strong adaptability, commodity, high production efficiency, high automation degree, low failure rate, convenient maintenance, etc.

 

Bridge Ship Unloader with Grab

 

This product can be used for the unloading of 3,000t-250,000t bulk ships for the material of different densities and particles (300-800mm) with grabs. The reclaiming grab bucket has simple structure with simple maintenance. It also can be used for the corrosive bulk material. It has good adaptability for the hatchways of the bulk ships, meanwhile, which will not be affected by the tidal level.

 

 

 

 

2. Chain Bucket Ship Unloading Machine

The chain bucket ship unloader is a continuous ship unloading machine for bulk materials unloading with its chain bucket. There is onboard conveying system to discharge these bulk materials to the wharf. The chain bucket ship unloader can be used for unloading limestone, coal, phosphate, ore sand, raw sugar and other materials, therein, the maximum capacity can be up to 3000t/h, and the maximum ship capacity is 100,000t.

 

This unloading machine has high unloading efficiency with 45%-50% unloading efficiency in the rated production efficiency when the ship unloader has stepped into stripping stage. It has small pollution because the conveying paths are sealed without dust pollution. Meanwhile, there is no frequent starting-braking operation, therefore, the noise is relatively small.

 

Less energy consumption: 1MJ/t~1.26MJ/t. Automation: Considering that the ship unloader has the similar reclaiming process in every layer of working surface, it is convenient to make operation and easy to realize the semi-automation and automation.
