Integrated sensorless anti-sway software takes account of the hoist and load type to ensure the load remains stable and does not sway. The anti-sway function improves safety, reduces cycle time to improve productivity and requires no special operator skills.
With VACON® Advanced Safety Options, the crane will able to fulfill safety requirements according to safety levels: SIL2, PLd, Cat. 3 (TÜV SÜD certified). SIL3 category meet up to 75kW. They improve flexibility by connecting safety devices within a plant.
Danfoss AC drives prevent load shocks at start and stop of lifting.For vertical motion, Danfoss provides smooth torque ramping to ensure that the load is held, stopped, raised and lowered in a perfectly safe mode at all times.
Provides a smooth load pick up when lifted in air. It protects the crane, the lifting load and the entire crane mechanism from extra stress.
Shock load prevention thus helps to increase the component life by reducing the mechanical stress on hoist mechanism.
When the load or hook is on the ground, there could be a slack at the rope, leading to rope damage or a jump out of the rope guides. This function is applicable only during lowering.
Smooth load placement and lower maintenance cost are the key benefits of this feature.
In case of mechanical brake failure the drive automatically detects, takes over(starts) and can bring the load down to the ground in a controlled way.
Catch dropping load support to enhance the safe operation of cranes.
Pega Hoist, a Czech company specializing in construction rack and pinion hoists, played a vital role in the erection of 828 metres of Burj Khalifa towers. The 12 Pega Hoist construction hoists on the site were controlled by VACON® AC drives.
An innovative 3000-tonne derrick pipe-laying barge built by Shanghai Zhenhua Heavy Industry Co., Ltd.* uses the world’s most advanced pipe-laying technology. The vessel’s 3000-tonne, 360° slew crane is driven by VACON® AC drives.
Danfoss AC drives dedicated application software for mechanical braking enables excellent hoisting speed accuracy, overhead crane safety, and brake control at Elgi Mukand.
Hybridization in the form of energy storage is one of the leading recent technologies and is rapidly becoming a megatrend. Energy storage offers us flexible ways to make supply and demand meet by bridging the lag between energy generation and consumption, dampening peak loads and bridging outages.
Designed for a broad range of demanding applications, focusing on higher power sizes and system drives
Chosen for its versatility and respected for its reliability, this AC drive has provided consistently awesome performance.
