Hoist for American cement plant
JD Neuhaus has completed a novel monorail hoist handling system for a cement plant in the USA.

Ultra-low headroom on chain hoists
A range of monorail mounted chain hoists from J D Neuhaus minimise the 'dead space' between the underside of the monorail track and the load point of the carrying hook
Crane drives suit more varied applications
The air or hydraulic powered geared travel units from J D Neuhaus were designed for use with crane bridges and hoists, but have been used for driving wheeled bogeys running on floor mounted rails.
This makes it ideal for use in cement, chemical and power generation plants as well as mining and offshore locations.
It is also particularly suited in general engineering applications where low headroom conditions and heavy load capacities apply.
The monorail hoist supplied is an adaptation of their established EH 80 series, and is designed for handling roller mills at the cement plant.
It provides a nominal 80t load capacity with three chain falls.
Whereas standard monorail hoists conventionally operate in a straight line, this equipment is fitted with four individual trolleys, giving it the capacity to successfully operate and negotiate a curved track.
Provision has also been made for load rotation, with the hoist below the traverse suspended in a link unit incorporating a toothed wheel operated by an air motor.
This can provide up to 270 degrees of rotational movement, but for the purposes of the installation, movement has been limited to 90 degrees only.
Further customising has been provided by replacing the standard lifting hook with a special load-carrying device equipped with two quick-release pins.
The whole unit is also fitted with a pendant controller to facilitate one-man operation.
The EH 80 has an output of 2.8kW per trolley and operates at 6bar pressure.
It has a G1.1/2 air connection and features favourable consumption of 5.2m3/min per trolley and 11m3/min for the hoist.
