We put your requests in a nutshell!
For about 30 years we have been constructing inspection facilities. We are sure that we can fulfill your special request – perhaps it is only the dot over the i of our wealth of experience.
We are full of ideas and feel able to solve your problems. Our strong points are intensive experience and specialist knowledge. Service and central location in Germany are advantageous to you.
We will be glad to visit you for conversation.
Inform yourself about our product range on the following pages and contact our specialists.
We are looking forward to new jobs and challenges in our priority areas:
Special facilities of hoisting and conveying technology
Inspection facilities for boiler plants, REA plants (flue gas desulfurization), etc.
Crane constructions, hoisting facilities
With our special facilities of lifting and conveying technology you will save a lot of time and money – and you can also spare your nerves. Gain advantage from our experience!
Waßermann & Schäfer GmbH
Construction of cranes and special facilities
Design, production, delivery and assembly of:
Hoisting facilities with electric and manual operation, e.g.
single-beam and twin-beam bridge cranes
single-beam and twin-beam ceiling travelling cranes
wall slewing cranes and slewing pillar cranes
hoisting units for freight transport through shafts
special hoisting facilities without rope migration
Additionally: Retrofitting of remote controls into cranes (radio-controlled and infrared-controlled). So crane control will be simply and fast.
Example: Our strong lightweight made of aluminium
This portable hoisting unit (on the right) is to be bought only once and can be used then at many places of action. It replaces expensive beams and cranes. Only one connection plate is to be installed at the possible place of action.
The component parts are designed that way, that no additional hoisting units are necessary for assembly.
We plan, design, produce and install special constructions of hoisting and conveying technology, e.g.
Devices for brick lining in blast furnaces and melting furnaces for other steelworks. The working platforms adjust to different inner diameters of furnaces by telescope constructions, e.g. from 7 m up to 13 m Ø. Loading can be fixed as required. The lifting motions are carried out by electric rope controls, which are permitted for people transportation.
Working cages for combustion cooling chimneys in steelworks.
These cages are designed as bearing steel constructions. The form is adjusted to the diameter of the chimney. We consider especially the travels through the angular flues.
Deposit platforms for freight transport through shafts in power stations and steelworks.
By use of deposit platforms heavy loads can be brought easily from the shafts into single floors.
On the left you can see another example for our actual production:
Platform for brick lining a melting furnace in a copper mill. The basic structural shape is round. You can reach all necessary inner surfaces of the furnace with additional enlargement elements. Lifting motions are carried out by three friction drive winches.
We offer custom-made solutions. Many years of experience are the guarantee for competent planning, design, production and assembly.
Even later we are at your disposal with our follow-up service.
Hinged aluminium working platforms for inspection of boiler rooms
Turning and withdrawing devices for working platforms
Inspection devices for:
Boiler plants, chimneys, coal bins, REA-absorber (flue gas desulfuization), garbage bins, fronts of boiler rooms, waste gas ducts, bunkers, etc.
Lead-in supports for working platforms,
Electromagnets for working platforms,
Electric controls for special facilities of lifting and conveying technology,
Halogen bulbs with strong power and quick-fastening devices.
Hinged working platforms
Viewing direction from boiler : aluminium working platform in hinged condition passing through opening of boiler wall.
The aluminium working platform in patented hinged design is a development of our experts.
Turning and withdrawing devices for working platforms
The turning and withdrawing devices for working platforms were developed by us and the design is patented as well (see on the right).
With this equipment it is possible to turn the working platform at the boiler walls without putting down the platform.
Inspection devices for boiler plants
On the left: Combustion chamber inspection device; on the right: Bulkhead inspection device
Inspection devices for chimneys
Assembly of an inner inspection device at the chimney of a steam generating station.
Lead-in supports for working platforms
We design lead-in supports for simple lead-in and return passage of working platforms through the bottom boiler opening, which adjust exactly to local surroundings.
On the left: The Elektromagnet lifting unit is to be used for lifting and transporting parts of iron and steel in connection with a suitable hoisting unit. Load attachment and load releasing times are reduced to a minimum.
On the left below: Roll-off safety devices for round parts like shafts and rolls are available.
On the right: The double-electromagnets fasten the working platform at the boiler wall. So unintentional swinging can be avoided.
Application at steel boiler walls or other steel wall constructions.
One example for our electric control is this switch cabinet of a combustion chamber inspection device with remote control, electric horn and telephone installation as well as isolation transformers, control transformers, contactor control and signal lambs, in rolling design.
Further supply of our electric department:
Control cable drums (rolling construction) with collector rings for drum winding of multiwire control cables.
Special control cable – 42 X 1,5 mm² with strain relief for large-sized suspension lengths, warning colour: orange, proven design.
Available for immediate delivery.
Spare parts for cranes and hoisting units.
Retrofitting of remote controls for cranes (radio and infrared control), see also crane construction).

The prescribed inspection and maintenance work at your inspection devices are carried out by our experts. We offer trainings for your staff for operation of facilities and behaviour in case of emergency. During inspection time of the boiler plants we place our staff at your disposal for operation of inspection devices and for assembly and disassembly.

On the right: Platforms for places difficult to get to, like in boiler plants, for example, belong to our aluminium constructions.
On the left: We also produce aluminium gibbets for turning round of two steel ropes; two automatic rope fix point devices are included.
