Low Headroom Hoists

HADEF offers a wide range of low and ultralow headroom hoists, which is our speciality. Machinery and industrial plants grow bigger and higher. Industrial buildings, however, require reduction of height to save cost for building, heating or air conditioning.

HADEF hoists are the ideal solution in such cases. Due to their low or even ultralow headroom configuration they require less space. These hoists are available for up to 100 ton capacity with either manual, electric or pneumatic operation.

Low Headroom Hoists
compact design up to 50 t	low headroom configuration up to 60 t	ultralow headroom configuration up to 100 t

Explosion-proof Equipment

Hadef International offer a wide range of products, spur gear hoists, electric and pneumatic chain hoists, trolleys and winches for use in areas at risk from explosion. Where there is little space available, explosion-proof hoists in low and ultralow headroom configuration are a solution.

Hadef International Offshore Equipment

Offshore environment demands the extreme from man and machine. Where the best is required, HADEF equipment offers solutions. Our offshore hoists, winches and cranes are in use worldwide, in Americas, Asia or on drilling platforms in the North Sea.

Together with our norwegian sister team, LM maskin as, we are a major supplier for individual offshore hoisting equipment with many years of experience especially in North Sea projects.

Ultralow Headroom Hoists

With limited space available, below deck on ships or on oil and gas platforms, HADEF equipment of low and ultralow headroom configuration offers the solution.

Lifting equipment used in marine and offshore environment require special features. Due to weather conditions, temperature and salty atmosphere, the surface protection has to be very strong Surfaces are blast-treated acc. to NORSOK standard on our own state-of-the-art roller conveyor blast machine.

This treatment increases material surface strength and offers the best preconditions for the special painting procedure that follows. Two 60 t ultralow headroom pneumatic chain hoists are used to handle a BOP system – Blow Out Preventer

Rack and Pinion Drive

HADEF trolleys and trolley-hoist combinations wich rack and pinion drive mechanism are used on floating installations or vessels. The rack and pinion drive keeps trolley and hoist in position during high seas and allows exact positioning when operating. HADEF Overhead Cranes can be fitted with rack and pinion drive for both, crane bridge and trolley hoist.
