PDW

Technical characteristics

• Large spectrum of lifting capacity (from 6,3 to 70 tonnes).
• Hoisting speeds 10 m/min and 20 m/min (ESR speed for hoisting.)
• True vertical lift, double girder trolley or fixed version or machinery only.
• Trolley speed control (inverter for variable speed drive) from 20 m/min to 61 m/min.
• Technical optimization of component design following modular design concept.
• PDW is designed according to EN standards (rope safety factor is always 5) and target for heavy duty class when product is requested according to FEM standard, lifting capacity is de-rated to comply higher rope safety factor.
• Reeving: 2 x 2 and 2 x 4 reeving’s available.
• Built in standard features to enhance the safety: hoist condition monitoring device; Upper and lower, slow down and stop limits for hoist with weighted ultimate upper switch; Trolley and bridge travel slow down & stop limits; Safety features: over speed and overload protection.
• PDW is equipped with ESR as standard.
