Controller Options

The JDN Monorail Air Hoist Series are available with the following controller options:

	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.

	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.
