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.

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
