Dellner Brakes is a manufacturer of hydraulic and electric disc brake calipers, locking devices, turning devices, brake discs and various pressure supply units.

Dellner Brakes delivers disc brakes and locking devices both in terms of single components and complete systems. Dellner Brakes’ complete systems are better known under the trademark STL-systems.

Industrial disc brake calipers

Dellner’s range of industrial disc brake calipers covers a wide range of applications, including mine winders, cranes, mills, conveyors, winches and hoists.

Dellner Brakes can provide different types of disc brake calipers in various sizes.

• EFP 2×75 – braking force 88,000N
• EFP 2×100 – braking force 118,700N

Locking devices

Dellner Brakes can provide manual, hydraulic and electric operated locking devices in various sizes:

• LM 20 – locking force 125kN
• LM 40 – locking force 250kN
• LM 50 – locking force 500kN
• LM 70 – locking force 750kN
• LM 95 – locking force 1,000kN

Pressure supply units

Dellner Brakes can provide several options of pressure supply units; for example:

• Hand pumps
• Hydraulic power packs – Series DH 2000
• Pressure intensifiers and control units
• Pneumatically operated hydraulic pump systems – type Compactus

Stopping, turning and locking (STL) system

Dellner Brakes’ STL-system is a multi-function unit that is all contained in one customer interface. Available functions are:

• Stopping – hydraulic disc brake calipers handle the stopping operation
• Turning – mechanical linkage(s) with hydraulic cylinder(s) are used for positioning the disc brake(s); together with an intelligent control system, the shaft is turned / indexed without the need of other turning devices
• Locking – the LM locking device has a specially designed tapered pawl that is engaged into a machined slot on the outer peripheral of the brake disc, which mechanically locks the shaft in place; the LM-device can be operated manually, hydraulically or electrically

The STL-system is a modular system. The customer can choose the functions that are needed. For example, if no locking function is needed, we can supply only the stopping and turning functions (ST-system) or if no turning function is needed, we can supply only the stopping and locking functions (SL-system).
