Ex-protection

 

AIR HOISTS: Maximum safety without extra costs

Areas with explosion hazards require special safety measures that are both expensive and time-consuming. But pneumatic hoists and crane systems have an important advantage: even the standard versions are suitable for the usage in potentially explosive atmospheres – and at J.D. Neuhaus this is a standard with no extra cost, resulting in cost-efficient safety for your facilities.

How is this possible? Compressed air does not produce sparks and cools at the same time! In working areas where even the smallest spark can trigger a fire or explosion due to explosive gases or dust, this is fundamental for safety.

ELECTRIC CHAIN HOISTS: Explosion protection leads to additional costs

With electronically operated hoists, there is always the danger of generating sparks and thus an enormous safety risk. For this reason, electric hoists have to be elaborately covered for use in potentially explosive atmospheres, which causes significant additional costs.

 

Protection classes

 

AIR HOISTS: Designed for maximum protection

Air hoists do not qualify as electrical equipment and therefore the IP system is not transferable. But comparable protection is already included in the design of the air hoist and offers enormous benefits: pneumatic hoists are particularly robust against environmental conditions while dirt and water are simply blown out by the air – without affecting the function of the device. Pneumatic hoists from J.D. Neuhaus are even optionally submersible.

 

ELECTRIC CHAIN HOISTS: Electricity holds potential dangers

The IP system and thus a variety of protection classes apply to electrical equipment. These indicate the suitability of electrical equipment for various environmental conditions, for example water or dust. If the protection class is inadequate, people are potentially at risk when operating electrical equipment. The vulnerable electronics are also the reason why electrical lifting equipment is often prone to malfunctions in the environmental conditions described.

Another danger when using electric chain hoists is lifting an overload because it can cause fire hazards. The reason: if thermocouples or trigger devices fail, the winding can burn causing enormous damage to the device and breakdown.

 

Emergency lowering

 

AIR HOISTS: Reliable even in an emergency

Power failure or system downtime are exceptions, but operators always have to be prepared for worst case scenarios to guarantee safety. Therefore, also in the case of an emergency you can rely on J.D. Neuhaus hoists: even if there is no longer a power supply, with pneumatic devices safe lowering of the load is possible at any time. When equipped with an emergency lowering device, an internal pressure accumulator enables emergency lowering. Next to this, when controlled via radio remote control a separate manual rocker switch is possible. In your facilities our pneumatic solutions can thus ensure maximum safety and accident prevention.

 

ELECTRIC CHAIN HOISTS: Power failure means downtime

Absolutely no movement – that is the consequence of power failures when using electric hoists. The load thus remains suspended in the air without being secured. This poses a potential hazard for operators and bystanders or can even cause damage.
