A Derrick Crane is docking equipment installed on vessels or dockside. Derrick crane consists of derrick and hoisting mechanism. There are 3 or 4 steel wires connecting the derrick and hoisting mechanism, which controls hoisting mast goes up and down. A separate steel wire sling runs under the hoisting mast with a hook as the hoisting mechanism.
Features of Weihua Derrick Crane:
1. There are 4 driving system for the hoisting mechanism, 2 driving system for luffing mechanism.
2. The whole derrick crane chassis adopt basin support on concrete foundation, which can effectively ease the horizontal and vertical deformation of the derrick crane.
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 control, half load lifting speed is 2 times faster than the full load lifting speed.
5. Inverter, encoder and electronic control system to ensure the 4 hoisting motors keep synchronous working.

SCHOTTEL launches high torque gear EcoPeller thruster
SCHOTTEL, a manufacturer of thrusters and steering systems, has introduced its new EcoPeller thruster (SRE). According to the company, the thruster is more efficient and reliable, using SCHOTTEL's patented new high-torque gear (HTG) gearbox technology.
     High performance and low cost
     High Torque Gear (HTG) is an efficient, rugged, and reliable gearbox with ideal gear geometry for low maintenance, reduced service costs, and streamlined enclosures that allow for improved hydrodynamic performance.
     Streamlined gearbox housing
     This high-torque gear enables a bevel gear of the same size to have a 15% higher drive torque, but the safety margin remains the same for the classification society, not just the internal standard of SCHOTTEL. Under the same driving torque, the underwater gearbox housing can achieve more streamlined shape and increase hydrodynamic propulsion efficiency.
     Robust, stable and reliable design
     In addition to increasing efficiency, customers will also benefit from reliability and gearbox damage. Design engineers have greatly reduced the risk of damage and damage to the gearbox structure during design, extending operational lifecycle and reliability, and reducing operating costs.
     Manufacture of ideal geometry
    Â
     With high-torque gears, SCHOTTEL has revolutionized gearbox technology to meet the specific requirements of the shipbuilding industry. The latest milling technology and calculation methods make this technology powerful and reliable.
     The Schotter Group, headquartered in Germany, is the world's leading manufacturer of marine and offshore propulsion and steering systems. Founded in 1921, it has been manufacturing and manufacturing azimuth propulsion and steering systems for more than 60 years. With a power range of up to 30 megawatts, it can be used in a wide range of ship sizes, with a worldwide sales and service network to ensure convenient customer service.
