AIR HOISTS: Sensitive Positioning on Point
Air hoists from JDN offer the noticeable advantage of stepless, variable speed operation ensuring precise and sensitive positioning of the load. This is particularly important not only to avoid damage to the load but also to prevent damaging equipment and machines, for example tool holders. Pinpoint accuracy is therefore worth real money, because damaged equipment and machines cause expensive repairs, replacements and downtime. Next to this, the accuracy of the movement of the load also ensures safety of the user and other present workers.
This high level of precision is made possible by our sensitive pneumatic valve technology: the stepless manipulation of the air flow ensures easy handling and infinitely variable speed – adaptable to the user’s needs and the individual load. In addition, JDN air chain hoists allow true vertical lift and means that lateral shifting of the hook when lifting loads is avoided and precise positioning is facilitated.
ELECTRIC CHAIN HOISTS: Stepless control causes extra costs
While a stepless control is standard when choosing a pneumatic JDN hoists, it means extra costs for you when using electric hoists. The reason: not only are additional frequency converters required, but possibly also thermoelements, because there is an increased risk of overheating of the motor. With wire rope hoists, vertical movements also result in a horizontally wandering hook, which makes precise positioning of the load very difficult.
AIR HOISTS: Compact, light & easy to handle
High-quality materials combined with smart design makes our pneumatic hoists compact. Thanks to their low weight, the devices are mobile – the small devices are even easily portable. At the same time, pneumatic hoists withstand even rough handling. Another advantage: this way the handling is made easier for the user and enables working more ergonomically. The short hook dimensions, lower headroom also ensure this.
ELECTRIC CHAIN HOISTS: Heavy design
Electric chain hoists are based on complex gears, electronic components and a larger number of building parts. As a result, these hoists have larger dimensions and are heavier. Flexible application or the use in smaller dimensional envelope applications is therefore often difficult.
AIR HOISTS: Around the clock usage
Continuous operation? No problem for pneumatic hoists. Our JDN devices offer a continuous duty cycle – depending on the lifting height and the size of the device. The advantage of pneumatics: the compressed air not only drives the device, but cools it at the same time. Additionally, pneumatic chain hoists are enormously insensitive to temperature. And even the number of times the unit can be switched on is unlimited. Perfect for use over long periods and in multi-shift working processes, for example in the automotive industry, to ensure efficient and uninterrupted processes.
ELECTRIC CHAIN HOISTS: Downtimes are inevitable
With electrical equipment there is always the danger of overheating. For this reason, cooling down breaks are necessary during which the electric hoist cannot be used. Due to the danger of overheating, this is especially necessary when lifting loads up or down high heights. As a result, the duty cycle reaches a maximum of 60% resulting in interruptions of your processes and operations.
AIR HOISTS: Real multi-talents for versatile use
Whether high lifting heights, horizontal pulling or challenging load capacities – pneumatic hoists from J.D. Neuhaus are up to any challenge. Even a tilted position is no problem, as pneumatic devices are operated oil-free and therefore no liquid can escape even in a tilted position. Therefore, pneumatic hoists are also ideally suited for special applications with individual requirements – for example, in the field of assembly applications within complex structures where the horizontal and inclined pulling of loads is necessary.
ELECTRIC CHAIN HOISTS: Limited application possibilities
Plant structures require in a wide variety of industries loads to be pulled diagonally. However, this is not possible with electronic hoists, because they switch off when pulled at an incline. Another major disadvantage is that the devices lose oil when tilted. This leads to contamination of the load and the surroundings and poses a safety risk.
