Mini series of air hoists

Special emphasis was placed on reducing the end-user’s total cost of ownership (TCO) of the hoist. Not only is the hoist optimised for overall efficiency, but it is available around the clock (365/24/7). Simple and fast maintenance further enhances efficiency. Also enhanced is highly sensitive, continuous control of hoisting and lowering speeds.

JDN has been able to increase the maximum speed at full load, with the Mini 500 achieving a 20% increase over speeds achieved by its previous model. Additionally, maximum speed can be adjusted without losing power at a given load capacity, meaning loads are better protected when necessary, without compromising speed control. J D Neuhaus has combined the advantages of direct and indirect controlling, so that the operator can lift and lower loads smoothly. 

New control lines bundled in one hose boost operating comfort by keeping the lines from twisting during operation.

The new Mini from J D Neuhaus even has something to offer when it comes to maintenance, since work can be performed directly on the lifting device without removing it from the beam, drastically reducing downtime during operation. And thanks to the NFC chip, the operator can access device-specific information and documentation on their smartphone as long as they have downloaded the JDN service app. This saves time and ensures that the necessary documents are available digitally.

The number of operating hours until the legally required general overhaul of the Mini has been doubled, allowing the new Mini to stay in operation for 800h. Such a development dramatically increases the device’s efficiency compared to the previous model, constituting an important contribution to the reduction of total cost of ownership. The developers at JDN also had some things up their sleeves when it came to flexibility: A standardised 'interface' for using various types of hooks, now available in steel and stainless steel. A load jacket and chain made of stainless steel and a motor casing of uncoated cast aluminium make the Mini suitable for use in fields such as the food industry.

Safety features include, upon customer request, optional fall supports for both the lifting and lowering phases, capable of holding the maximum capacity of a hoist should it come free of the supporting structure. In addition, the new limit stop offers another safety feature, switching off the hoist and lowering movement as soon as the bumper touches the stop valve. This slows the movement and keeps the chain from getting overloaded. These and other new safety features enhance occupational safety and minimise safety hazards and wear risks.

The new JDN Mini is available in four carrying capacities, 125, 250, 500 and 980kg. In collaboration with customers from a wide variety of industries, J D Neuhaus has developed a product designed for the most varied fields of use: it can be operated in wet and dry environments, when it’s hot and cold, in dust-free rooms or under extremely dirty conditions and in areas where an explosive atmosphere (Zone 2) is present. For the first time, JDN has also used high-tech synthetic materials in order to replace high-energy materials while also fulfilling the requirements set and reducing the overall weight of the hoisting device.

For managing partner Wilfried Neuhaus-Galladé, it was especially important to constantly align development with users and their requirements in order to achieve 100% market relevance and to incorporate the demands of the market into the new series.
