JDN offers air driven cranes suitable for working inhazardous areas as standard.

The programme includes explosion proof

� Overhead travelling cranes� Underslung cranes� Slewing jib cranes

All these cranes can be adapted to your individualrequirements with complete bespoke installations ourspeciality.

According to your requirements JDN air hoists in motortrolleys or monorail design are integrated in the cranedesign. User friendly pneumatic pendant controls offering two speed or infinitely variable speed controlare available depending on the application.

ADVANTAGES OF JDN AIR CR ANES� Expertise gained over many years in the manufacture

and design of pneumatic lifting and control equipment� Worldwide service� Insensitive to dust, humidity, aggressive atmospheres

and temperature range between –20°C and +70°C� 100% duty rating of motors for long duty cycles and

constant switching� Large power reserves due to high starting torque of

air motors� Fail safe breaking in case of air supply failure� Overload protection and emergency stop features� Pneumatic controls, also with special functions� Special limit switch arrangements for end travel,

anti-collision and protected zones� Remote radio and special control systems available

on request� By-pass operations (e.g. intentional by-pass a

limit switch)

DIFFERENT T YPES OF JDN CR ANES IN DETAIL� Single or double girder overhead travelling cranes� Underslung cranes with special low headroom trolley

designs� Slewing jib cranes� Overhead travelling or underslung cranes with

synchronised hoist arrangements� Overhead travelling or underslung cranes with parallel

hoist arrangements� Load capacities up to 50 t� Spans up to 18 m

JDN crane designs include our robust chain hoists.Alternatively JDN wire rope hoist units are availablewith load capacities from 1.25 t to 10 t. Depending onthe site conditions the crane is individually designed tosuit the customers requirements.For travelling and lifting we utilise our proven JDN airmotors. If required we can offer a complete installation,commissioning and servicing package. Special require-ments such as material certification to EN 10204 3.1.Bare also available on request.

� For overhead travelling cranes up to 10 t.� For crane manufacturers to built explosion-proof

air cranes.� JDN end carriages can be offered with suitable

pneumatic drives.� JDN hoists, trolleys and end carriages are explosion-

proof, enhanced spark resistance optional.� JDN energy chains guarantee a secure and space

saving guidance of control and energy lines.

� Up to 4 t: max. span 10 m, up to 10 t: max. span 13 m as standard, other versions on request.

� Safety accessories as main air emergency stop arestandard elements.

� The junction box is the central element, where thelines for control and air feeding are connected andthen directed to the crane drives and the trolley withhoist (via energy chain).
