Description
The Donati DRH Electric Wire Rope Hoist with Suspended Trolley is a robust and versatile industrial lifting solution designed for applications requiring both vertical lifting and smooth horizontal movement along a crane beam. Engineered for use on single girder overhead crane systems, this configuration combines Donati’s proven DRH hoist unit with a powered trolley, delivering exceptional performance, precision, and long-term reliability.
What is a Suspended Trolley Hoist?
With a working load limit of up to 20,000 kg, this suspended trolley hoist is ideal for manufacturing plants, engineering workshops, warehouses, and assembly lines where efficient load transport and accurate positioning are critical. The system enables operators to move loads seamlessly along the beam, improving workflow efficiency and reducing manual handling.
The hoist is suspended beneath the crane beam via hinge-pin supported bars, allowing it to travel smoothly while maintaining excellent load stability. This design ensures consistent performance, even when handling heavy or uneven loads, making it suitable for demanding industrial environments.

Powered Beam Trolley
Two trolley configurations are available to suit different operational requirements. The standard (normal) trolley is designed for straight beams and typical industrial applications, while the articulated trolley allows the hoist to travel along curved beams, making it ideal for complex layouts or production facilities with radiused track systems. This flexibility makes the DRH suspended trolley hoist a highly adaptable solution for bespoke crane installations.
The trolley system is engineered for durability and precision, featuring idler and drive wheel assemblies with precision-machined steel wheels mounted on spherical, permanently lubricated bearings. The drive wheels are connected via a crown gear transmission bar, ensuring smooth, stable, and vibration-free movement during operation.
Powered by a conical self-braking motor, the trolley provides controlled acceleration and deceleration, allowing for precise load positioning and enhanced operational safety. This is particularly important when handling sensitive or high-value components where accuracy is essential.
Donati Hoist Built to Specification
The system offers a range of trolley travel speeds, including both single-speed and dual-speed options, allowing users to tailor performance based on operational needs. The integrated helical gear reducer, permanently lubricated in an oil bath, ensures quiet operation, minimal wear, and reduced maintenance requirements.
The hoisting unit retains the full performance capabilities of the DRH range, including 2 or 4 rope fall configurations, lifting speeds from 2 m/min to 12 m/min, and hook travel up to 58 metres, depending on drum size. This ensures the hoist can be customised for a wide range of lifting applications.
Hoists With Built-in Safety Features
Electrical safety and reliability are ensured through IP-rated motor protection, thermal sensors, and integrated overload protection systems, providing safe and consistent operation in demanding industrial conditions. The hoist is designed for use in temperatures ranging from –10°C to +40°C, making it suitable for most indoor environments.
All components are precision-machined and protected with water-repellent electrostatic paint, offering excellent resistance to corrosion and ensuring long-term durability even in high-use industrial settings.
