Duty cycle is amongst others an important area of focus. Electric drives can only be used for intermittent operations (S2 duty), so are not suitable for continuous use. Conversely, JDN says its pneumatic hoists have no downtime and a 100% duty cycle rating and in addition, its pneumatic hoists can work constantly without causing excessive temperatures thanks to the patented design self cooling gearbox, where decompressed air flows through channels within the gearbox to cool the gear train. This offers a great benefit to end users as hoists can be in uninterrupted use over multiple shifts.
JDN says with regard to variable speed, a pneumatically operated hoist is able to offer easy, accurate and wide-ranging speed control at low cost, enabling simple, sensitive and accurate positioning of loads in all environmental conditions. In comparison, an electric hoist will require a frequency converter (also known as a VFD) and shielded wires to prevent radio interference, while the motor will need thermo-elements to avoid increased heating at the windings.
