the closing of the clamp, and a hydraulic cylinder fed by a suitable hydraulic unit providing the opening. • This Rail clamp is static storm brake, suitable for small to medium forces from 25 to 800 kN • Generally considered to be used as parking devices (safety against movement from wind).
A brief history, strong partnership and further Global expansion A company renowned for rail clamps is RIMA S.R.L an Italian based company who began designing and manufacturing their products in the field of hydraulic equipment and storm brakes at their factory in Varese in 1967. From there two subsidiary companies in Taranto, Rima Fluid and Rima Impianti S.R.L became active with the assembly, repair, and trade of electric and hydraulic components.
an already productive market, as we are in a position to offer services and repairs through our workshop in Durban to old, existing and new brakes, as well as assist in finding a suitable brake for any application”.
In April of 2020, it was announced that one of the leading German Industrial Brake manufacturers, DELLNER BUBENZER GROUP, along with its subsidiary PINTSCH BUBENZER GmbH had an agreement to acquire RIMA S.R.L a deal that would pave the way for the DELLNER BUBENZER GROUP’S rapid global expansion.
RAIL CLAMPS, Strong, Resilient and Dependable. When we think of cranes and mining equipment, we think of the large-sized ship to shore Harbour Cranes, and the huge sized rail-mounted bucket excavator, both imposing pieces of equipment require a sturdy braking system, particularly during heavy storms and gale-force winds.
RIMA and the Southern African Market
The braking systems for these hard-working machines, come in the form of heavy-duty rail clamps, and they are designed to safeguard against runaway equipment, that could potentially be destroyed or cause damage to other equipment or buildings if not restrained correctly.
Derek Colyn, General Manager of Huebner Speed Monitoring, had the following to say ‘’ We have been representing and supplying PINTSCH BUBENZER Products in Southern African, as well as West Africa for the past five years. “Although Rima has been available in Southern Africa for the past couple of years, the acquisition of Rima S.R.L into the DELLNER BUBENZER GROUP will strengthen
Rima offers four brake types: Rail Brake TM• Composed of one steel frame, two rail guides and two jaws operated by springs which generate
Rail Clamp Self-Blocking Type TA and Type TR• As Storms Brakes the self-blocking rail clamp starts working and pressing the rail sides only if the wind forces begin to overcome the gantry brakes capacity. • As the crane begins to move, the rail clamps will begin pressing on the rail sides with a force that is proportional to the wind force deducted from the gantry brake force. Rail Brake TP• This unique Rail Brake is suitable for medium forces from 130-500k (securing cranes against wind force). • These brakes work by pressing down on top of the rail by disk springs, and are released hydraulically, and require a daily cycle of opening and closing to ensure proper parking utilisation. Wheel Brake FR• Devoted to parking and securing the crane in a stowed condition. • In emergencies, they can be operated as dynamic brakes to stop the crane • The brake shoes push on the two sides of the wheel, actuated by springs, and released by hydraulic power
