JD NEUHAUS offers three types of hoist trolleys for lateral motion of suspended loads: manual trolleys (LN) for pushing or pulling by hand; reel chain trolleys (LH) for moving by unwinding the reel chain; and motorized trolleys (LM) powered by an air motor. While the standard industrial series stops at a single 20-metric ton trolley, higher capacities can be achieved with the benefit of eight-wheel and 16-wheel systems. Additionally, custom designs or utilization of the monorail series offer traversable load-placement for the entire JDN catalogue of capacities up to 100 metric tons.
All JDN trolleys offer explosion protection to Ex II 2 GD IIA T4/II 3 GD IIB T4 classifications. Higher classifications are available on request. For instance, with even further increased spark protection for explosion group IIC, the trolleys incorporate running wheels and travel gearing manufactured in bronze for an impressive EX II 2 GD IIC T4 rating.
Careful design and development have led to numerous standard features, which with simple installation and a robust structure requires little maintenance. Anti-climb and anti-drop devices also are included as standard. JDN trolleys are designed to tackle all sorts of applications, including curved beams. JDN specialists will offer advice on any project where curved beams are involved.
For those seeking an even higher specification, options for JDN trolleys include a rack-and-pinion drive for safe load-handling, a spark-resistant package, and offshore paint to suit rigorous operating environments. Energy can be fed by various systems, including energy chain, C-shaped rail, square rail or spiral hose, to best suit application requirements.
For applications that have restricted headroom, JDN also offers a special-purpose series of low-headroom trolleys, meaning tight load placements can still traverse economically utilizing JDN’s special low-headroom design. The standard range offers carrying capacities from 0.5 to 6.3 metric tons, with higher capacities available for custom built projects. This, along with other JDN traversing solutions, creates a multitude of trolley capabilities.
Also able to negotiate overhead rail curvature, JDN’s low-headroom trolleys feature extended tie bars for bulky or elongated loads. The same options and energy feeding systems available for JDN’s standard trolley range, can also be offered to users of low-headroom versions, with the addition of hose trolley energy feeding to the list of choices.
All hoists and trolleys can be remotely controlled by the recently introduced JDN radio-control systems, offering ease-of-use and convenience. The remote controls are an effective alternative when long control hoses are required, and for use in hard-to-reach areas, providing simultaneous control of multiple hoists and trolleys. Comprising a transmitter and receiver, the JDN-RC (Remote Control) is available for both new and retrofit applications.
