Rail brakes work pressing down on the top of rail by disk springs. Brakes are hydraulically released. Usual parking utilisation requires a few closing / opening cycles per day.

These rail clamps are storm brakes static suitable for small to medium forces. They are spring actuated; the spring exercise the closing force while an hydraulic cylinder fed by a suitable hydraulic unit provides the opening.

These rail clamps are storm brakes suitable for high forces. They are self-blocking type; in case a force acts on the crane and tends to put the same into motion, they press on the rail sideways.

These rail clamps are storm brakes static suitable for small to medium forces. They are spring actuated; the spring exercise the closing force while a group composed by electric motor, gear reducer and a ball screw provides the opening.

These couplings are for use in application with high dynamic loads. Damping of peak torques and vibrations as well as electrical insulation between motor and gearbox are key features that make this type of coupling ideal for use.

The EBA is a powerful drum brake with braking torques from 24 (ft-lb) to 9000 (ft-lb) that meets AISE (TR11) & NEMA (ICS 8) standards.

The EBH series is designed according to DIN 15435. This design is very compact and can be used in tight motor gearbox combinations.

The EBN series is designed according to DIN 15435 and has been in use in various industries for decades. EBN-2St modification: the drum brakes solution for Bridges and Sluice Systems

These couplings are for use in application with high dynamic loads. Damping of peak torques and vibrations as well as electrical insulation between motor and gearbox are key features that make this type of coupling ideal for use.

The FKE is best suited for applications with light starting and stopping loads. It is also commonly used as a slip clutch or tension brake within light horsepower and torque applications.

The FKR is often referred to as a coupling, as its expanding neoprene rubber facing engages the interior diameter of the drum directly. The resulting friction generates significant torque within a small package. 

The FK is well suited as a clutch or brake for a variety of high speed and low to medium torque power transmission applications where high heat generation is not a factor.

The FKT is well suited for applications with the most demanding equipment where severe clutching and braking is required.

The FM is designed and manufactured for marine applications, mainly for use on diesel-driven reduction gears.

Our hand pump can be used to simply activate the Dellner brake calipers. It also acts as a back up system for the primary pressure supply system.

The hydraulic rotary actuator is a device which transform hydraulic power (pressure and flow) in mechanical power: torque and angular speed.

A hydraulic rotor lock offering up to 250 bar pressure with an activation time of 60 seconds.
