Hydraulic chain hoists are very similar in features to Pneumatic hoists except the hoist is powered by hydraulic oil as opposed to being powered by a compressed air line. The main advantages of the hydraulic lifting chain hoist is the same as Pneumatic chain hoist in that they are both 100% duty cycle. What this means is that the hydraulic powered chain hoists are suitable for constant use such as in a production environments, it also means that they are suitable for long heights of lift where an electric motor would overheat. Hydraulic chain hoists can be supplied with variable lifting speed, the more the operator depresses the button the greater the amount of hydraulic fluid passed by the valve and the faster the hoist will raise or lower. Because there is no electric power source air hoists are also more suitable for use in potentially explosive areas where a spark can cause an explosion. Hydraulic chain hoists can more cost effective solution when Atex certification is needed, far cheaper than the equivalent electric Atex hoist and are more suited to applications in harsh environments which is why they are the hoist of preference in the off shore oil and gas producing and maintenance sectors. We also offer hydraulic subsea hoists designed to be operated under water. As with other lifting chain hoist the hydraulic hoists supplied by LiftingSafety are all from a top quality manufacturer JDN (JD Neuhaus)
