Open Winch& Heavy Duty Winch for Double Girder Cranes

Open winch, also called heavy duty winch, due to all the elements are manufactured with independent and different sub-assemblies for easy maintenance, delivering higher lifting capacities and speeds, and meeting higher FEM hoist duty classifications. Our heavy duty winch offers a wide range of lifting capacities from 5~550t, span of 10.5m~ 31.5m, lifting height of 1m-30m, working class（A7), also can design and manufacture according to requirements.



Designed for lifting heavy loads and equipment, electric open winch from DQCRANES feature modular designs that use independent sub-assemblies for easy access to components for maintenance, servicing, calibration and inspection.

Heavy duty open winch for sale to Pakistan:

• QD30/15T, Span 24M, Lifting height 14/16M；

• QDY50/15T, Span 24M, Lifting height 18/20M；

• 400V50HZ3P

Open winch design features:

• In general, open winches allow higher lifting capacities, higher speeds and higher FEM working groups.
• Direct shaft from motor to gearbox to drum with flexible and intermediate assemblies, absorbing the shocks at the time of lifting.
• True vertical lift, with stable hook at the lifting time.
• Easy access to the components for easy maintenance.
• External brake for easy access and maintenance.
• Wire rope press roller/ Wire rope anti-overlapping is to avoid the wire rope come out from the drum hole.
• Flexible, adaptable through different installation variants.
• Low-maintenance, low-noise direct drive with disc brake and centrifugal mass.
• Smooth starting and braking characteristics: with frequency inverter as an option.
• Explosion-proof versions or off-standard solutions through engineering.
• Note: These type of electric open winches are produced on demand to address special needs such process cranes with special features of capacity, safety, speed or other requirements.

Electric open winch advantages and applications:

• This double girder electric hoist winch trolley has the characteristics of compact design, light weight, small wheel pressure and uniform load distribution.
• Greatly reduce construction costs, reduce energy consumption costs, and make maintenance more convenient.
• Compared with the traditional winch hoist, the open winch crane can reduce the space above the structural size. According to the different lifting tonnage, the reduction range is between 20-50%. The larger the lifting tonnage, the lower the reduction range bigger.
• Electric open winch is a major development in the crane industry, aiming to improve production efficiency, reduce maintenance costs, extend service life, improve customer return on investment and create value for customers.
• Industrial Electric Winches are widely used in paper industry, power industry, waste power generation industry, steel industry, petrochemical industry, metallurgical casting industry and other industrial fields.
