An expert assembly of a hoist is an essential and necessary step, in order to achieve a safe and troublefree operation. This is true both for the hoist itself, and just as much for the crane gantries, on which the overhead cranes and portal cranes operate. If the assembly is carried out precisely according to plan, then abnormal wear and tear is as good as excluded. The reliability and the operating life of the hoist is substantially improved thereby. and unexpected downtimes are reduced to a minimum.
The precision (measuring) tools, and the modified accessories that are used by our technicians, make an efficient and safe assembly possible. Safety is a primary requirement, also during the assembly, and this is an entirely implemented according to the requirements of a Contractor's Safety Checklist (VCA) certificate.


You require an optimal availability of your hoists, namely a minimum of unexpected downtimes. Expert preventive maintenance at regular intervals is a (legal) requirement. And no one is better suited for this than our technicians, who do nothing else, year after year, and who benefit from permanent training.
And with our REMAIN programme, we keep track of all parameters and make sure that you benefit from substantial savings on the operating costs. In addition, you can also make use of our 24/7 emergency intervention service, which will solve even rare problems in no time at all.
Tracking via our REMAIN programme was started up in 2001. In the 15 years of its existence it has become perfectly clear that regular and expert preventive maintenance drastically reduces the number of unwanted downtimes. In addition, many remedial maintenance measures are not carried out after an unwanted failure, but usually on a good moment that has been planned far in advance, ensuring a minimum of hindrance to the production process.



“Moving to Green” is the name of a dynamic process, which was started up by DEMAN in 2010.
We successfully achieved a reduction of our ecologic footprint, through all kinds of actions that fall into three main areas:

  1. Energy savings
  2. Limiting emissions
  3. Sustainable products

Duurzaamheid Deman





Constructiewerkhuizen DEMAN started up modestly in 1945, with the construction of flax processing machines. The inventive Maurice Deman (°1904 † 1998) was the founder of the company, and on 13 February 1953 it was transformed into a limited liability company.
Since the area around Courtrai had been a centre of the flax processing industry for many years, there was a direct and very large market for a totally new, combined flax-rippling and combing machine that included seed removal.
The first telescopic construction crane was produced in 1955. Due to the unique self-constructing system, and besides flax machines, this new product became a big success. After manufacturing more than 5,000 units, production was stopped in the middle of the 70s.
Under the management of Eric Deman, the first DEMAN overhead cranes and portal cranes were built in 1969, together with the first DEMAN concrete plants. The demand for overhead crane grew so quickly that the other products, which were strongly sector-oriented, were removed from the product range.
The 2,000th overhead crane was built in 1995, and in the meantime we are not far from the number 4,000 ... .
Since 2011, intelligent solutions have been successfully applied on a major scale, and in 2016 this led to the establishment of the "TRISKEL competence centre", which clearly shows the direction in which our future is going…
