Pneumatic Chain Hoists with 2 bottom hooks for horizontal transport of loads, 1 Tonne to 6 Tonne

Model:

JDN M Series / PCH-2743

Capacities of 1t to 6t, Air Pressure of 4 bar

JDN Air Hoists of the M series were originally developed for underground mining operations. Due to their multiple applications they are nowadays also deployed in most different industrial fields. Basically they have the same features as the hoists of the PROFI series but operate with an air pressure of 4 bar only. Two different control systems are at your disposal.

Standard Features

suitable for application in hazardous areas with danger of explosion
Two chain falls for alternate working
specially suitable for horizontal pulling

LiftingSafety Review:

The JDN M series air hoist was originally introduced as a mining industry hoist and may well be the only low pressure air hoist currently manufactured requiring only 4 bar of compressed air pressure. Capacities available from 1 to 6 tonne SWL and certified for use in some potentially explosive environments. The M series of pneumatic hoists are particularly suitable for horizontal pulling applications. Please contact us for further technical specifications or for a discounted quote.

Controller Options

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

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 is that 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.
