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.
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.
Weihua Bucket Wheel Stacker and Reclaimer for Thermoelectric Company
Manufacturer: Henan Weihua Heavy Machinery Co., Ltd.
Work place: Jingneng Qinhuangdao Thermal Power Co., Ltd.
Duty: The core equipment of the power transmission line of the power plant, responsible for the storage and handling of coal-fired power plants.
Model: DQL1100/1500·30
Regular use: 1 set for working with 1 set backup or 2 sets working at the same time
Stacking capacity: 1500t/h
Reclaiming capacity: 300~1100t/h (adjustable frequency conversion)
Working coverage radius: 30m
Stacking height: 11m on the rail, 1.5m below the rail
Rotation angle: ±110°
Boom pitch angle: +10°~-13.9°
Features:
1. Multiple operation modes
Single action mode, manual mode, automatic mode and local mode can be switched freely according to different operation requirements without any interference effect;
2. Automatic controllable operation, real-time data feedback
The PLC main control device realizes the full automatic control of the stacker and reclaimer operation, collects the pile shape data through the instrument, and feeds the material storage condition in real time;
3. Three-dimensional anti-collision, accurate and reliable positioning
The three-dimensional anti-collision system is based on high-reliability and high-precision positioning system detection and attitude detection, and realizes anti-collision between equipment and material piles, equipment and equipment, equipment and devices along the track;
4. Timely warning, double security protection
Mechanical and inductive limit switches are set at each operating mechanism, and warning warnings and limit parking points are set in the program monitoring to establish double safety protection;
5. Two-line intelligent lubrication, reducing labor intensity
The whole equipment adopts electric centralized lubrication, which greatly reduces the labor intensity; the two-line intelligent centralized lubrication system is adopted, and the lubrication effects of the front and rear lines do not affect each other. The intelligent monitoring system can indicate the fault point and reduce the manual inspection intensity;
6. Versatile and cost-effective
It adopts the full-function double-tailed car layout to realize easy material stacking and reclaim function, multi-functional and cost-effective.
Coal handling line:
Stacking: coal transport by train → dumper system → coal pit → ground conveyor belt system → bucket wheel stacker and reclaimer → coal storage yard.
Reclaiming: coal storage yard→ bucket wheel stacker and reclaimer→ground conveyor belt system→coal storage bin→transport belt system→boiler.
Stacking and reclaiming:
Stacking: coal → ground belt conveyor → auxiliary tail car → main tail car → main tail car head hopper → boom belt conveyor guide trough → boom belt conveyor → coal storage yard.
Reclaiming: coal→ bucket wheel mechanism→ boom belt conveyor→ center drop hopper→ ground belt conveyor.
Weihua provide 2 sets of bucket wheel stacker and reclaimer for the 2×350,000 kW cogeneration project of Jingneng Qinhuangdao Development Zone, which is an important project for Qinhuangdao City.

Ship-to-Shore Gantry Crane / Weihua Crane
Ship-to-shore gantry crane is called STS or QC, which is constituted by steel structure, lifting mechanism, pitching mechanism, tilting mechanism, crane traveling mechanism, trolley traveling mechanism, machine room, spreader, electrical equipment, necessary safety devices and other accessories.
According to the different trolley types, this ship to shore gantry crane can be divided into three kinds: traction crane, semi traction crane and self-propelled crane. PLC control system and CMMS malfunction detection system make it automatic malfunction detection and diagnosis.
There are sufficient communication and lighting facilities making it work safely and reliably. Anti-sway control system can be installed on the STS crane according to users' demand.
