Air operated Monorail hoists meet industry challenge

Some air operated monorail hoists from J D Neuhaus feature upgraded air motors and all models can be customised with additional accessories to suit specific industry challenges. Operating off a pneumatic air pressure of 85psi (6 bar), the hoists avoid the potential hazards and dangers associated with electrically powered equipment when operating within areas with high humidity or potentially explosive dusts or gases. With carrying capacities ranging from 10 to 115 tonnes, these hoists are suitable for a wide range of both general and specialised engineering applications including outdoor installations.

Where confined or restricted headroom conditions are involved then ultra-low monorail hoists are also available for loads from 4 – 100 tonnes. A high performance patented vane motor (as now fitted to these hoists up to 12 tonnes capacity) combines self-lube operation with sturdy design features and a reduced number of component parts. This simplifies setting and assembly procedures while providing long, trouble-free performance with low maintenance requirements.

All these hoist products can also be supplied suitable for use on curved beam supports, making them particularly suitable for transfers between production lines. Optional electronic indicators of the hook loading, in addition, can be provided as an attachment to the pendant controllers. A further recent introduction includes perforated chain storage boxes that prevent the retention of water or other environmental site debris. This option is particularly suited to land rig operations.

JDN air hoists are also classified for explosion protection when operating within hazardous area conditions as can be encountered within chemical, mining, tunnelling, foundries and offshore industries etc. Standard hoists are marked Ex II 2 GD 11A T4/Ex II 3 GD 11B T4, with increased spark protection provided as an option up to explosion level 11C.

As well as being insensitive to humidity, dust and temperatures from -20°C up to +70°C, these compact hoists incorporate instant starting with a fail-safe disc brake for safe load-holding in the event of interruption to the air power supply. Anti-climb and anti-drop devices are also included, with pendant controllers and emergency shut-off valves. Overload protection, rack and pinion drive, two-speed trolley travel control and a filter silencer can also be provided as optional accessories.
