Air hoists provide safe, efficient lifting
- May 20, 2014
- Product Release
- Materials Handling
Upgraded to combine quieter operation with faster lifting/lowering speeds and increased energy conservation, J D Neuhaus’ Profi TI hoists are designed to offer safe and efficient lifting and handling for general engineering and industrial applications.
Typical applications include aircraft construction, assembly lines, chemical plants, dairies, foundries, mechanical engineering, on- and offshore drilling rigs, power plants, refineries, quarries and mines, sawmills, shipyards, and automotive plants.
The hoists operate from either a 4- or 6-bar air supply. Those with 3- to 50-metric-ton lift capacity are suitable for medium to heavy lifting requirements. For extreme heavy lifting, hoists are available with lift capacities up to 100 metric tons. They can be used in tandem or parallel configurations to provide safe lifting for larger or extra-heavy loads.
All hoists are provided with single-point top suspension and can be fitted with trolleys for overhead monorail mountings to facilitate horizontal travel. Trolleys with manual, reel chain, or motorized operation can be supplied, combined with a standard hoist lift of 3 meters, with other special lift requirements also accommodated.
Optional control systems can be fitted for varying hoist controls, including universally applicable rope/chain types or an FI sensitive control. A corrosion-proof type E control offers single-speed sensitive operation, and type F multilateral controls provide for multifunction and variable-speed hoist lift/travel options. Remote control and electropneumatic interface operation can also be provided.
Hydraulically operated hoists, including a special-purpose unit capable of operating at arctic temperatures as low as -45 degrees C, are available. Special-purpose requirements, such as underwater operation, also can be accommodated, typically as required for offshore or ship-repair applications. Other hoists are designed specifically for use within the mining industry.
For lighter-duty operations, Mini hoists are available for individual-powered lift applications of 275, 550, 1,100, and 2,160 lbs., operating at 6-bar air pressure. These universally deployable hoists are suitable for handicraft workshop operations, including horizontal pulling. A manually operated overhead trolley also is available for beam mounting, together with a manipulator version of the Mini that facilitates safe, single-handed lift/lower/traverse and load-positioning operations.
All hoists are designed for applications in potentially explosive or otherwise hazardous atmospheres and carry Ex classifications of (Profi range) Ex II 2 GD IIA T4/II 3 GD IIB T4, with optional spark protection being available for explosion group IIC and to achieve a rating Ex II 2 GD IIC T4. The explosion classification for the Mini is Ex II 3 GD IIA T4. All hoists also offer lube-free operation, combined with high levels of safety and with low maintenance, the company reports. The hoists also are insensitive to dust and humidity for operation within a temperature range of -20 to 70 degrees C.
