JDN Low Headroom Trolleys

The trolley for areas where headroom is restricted

Carrying capacities: from 0,5 t up to 6,3 t

When only low headroom is available and the standard trolleys don't meet the requirements we recommend JDN low headroom trolleys where the air hoists are horizontally mounted.

JDN Controls

JDN Air Hoists and Cranes are available with various controls to suit your special necessities.

Rope Control

Universally applicable for any control length

This control enables a sensitive starting and stopping. Lifting and lowering speeds are infinitely variable. The rope control is available for all PROFI hoists up to 25 t carrying capacity. The PROFI 37 TI, 50 TI and 100 TI are fitted with a pull chain instead of a cord.

FI-Control

Sensitive control, very easy handling

This FI-Control allows very sensitive regulation of the speeds. Its handling is very easy and comfortable due to the ergonomic design of the synthetic housing. The use of non-rusting materials allows the application in areas with aggressive substances in the atmosphere. The control hoses are enclosed in an outer sheath which protects them from ambient influences.

E-Control

Low maintenance, corrosion-proof

The very robust brass valve distinguishes the E-control. The low weight and the praxis-orientated design result in an easy handling. Sensitive speed control is not possible.

F-Control

Multilateral due to different housings

The F-control consists of unbreakable synthetic material resistant to ambient influences. The ergonomically designed housing enables a good handling. Up to 18 different control functions can be integrated as for example key switch, double stage travelling speed or simultaneous control of several motors. As a special extra the F-control can also be delivered with infinitely variable control of hoisting and travelling speeds.

Controls for JDN Air Hoists M Series

DS control

The operating air is connected to the hand control valve. A built-in pressure regulator prevents to overload the hoist in case of inadmissably high pressure. The motor connection housing of the DS control has an oiler that stops automatically the oil flow when the hoist comes to a standstill.
Another advantage: the oiler is situated directly at the motor. The operating air gets immediately to the motor when the hand lever is actuated. The hand lever is spring loaded and returns automatically to zero position. This forced release serves at the same time as an emergency stop. The control is for two-hand operation. The DS control is available for all air hoists of the "B" and "M" series.

PS Control

The PS control is for single hand use. It operates indirectly according to the ventilation principle. The operating air is connected to the control valve of the motor. The control pistons of the motor are actuated by the push buttons of the hand control. The push buttons automatically return to zero position. In the control valve of the motor is a pressure regulator which protects the hoist from inadmissably high pressure. The integrated oiler provides the necessary lubrication. The PS controls are available for the air hoists M 63 D, in EC version with emergency stop as standard.

Controls for JDN Air Hoists in Motor Trolley and JDN Monorail Hoists

For controlling JDN air hoists in motor trolleys and JDN monorail hoists we recommend the E-fourfold or F-control. The cord control is also possible.

Control for JDN Cranes

For controlling JDN cranes the F-control is the most suitable one because of its multilateral housings.

Operating Convenience via Radio Control

To overcome larger distances between operator and crane or to use hoisting equipment in remote areas the JDN Radio Control offers a particularly convenient and safe operation. The radio control is also available in explosion-proof version.
