Johnson SML Series Thruster Drum Brakes

The Johnson SML Series Thruster Drum Brakes are a versatile and reliable solution for a wide range of industrial applications. With 16 models available, these brakes are designed to meet the demands of mechanical handling equipment, cranes, winches, stacker reclaimers, ski lifts, and conveyors. Each brake unit features a standard Eltma Elhy EB series IP56 enclosed thruster, a robust fabricated steel mechanism, non-ferrous bushed major pivots, and non-asbestos friction linings that are built to withstand high temperatures.

Engineered for adaptability, the Johnson SML Series offers a variety of options to enhance performance and meet specific operational needs. Customers can choose from features such as a self-adjusting mechanism, mechanical release lever, and limit switches to monitor release, set, or wear. Additional options include hydraulic override by remote pedal, electronic modulated torque, and a reverse brake mechanism thruster. For specialized requirements, the brakes can be customized with special materials and finishes, high-temperature viton seals, and an explosion-proof design.

The thruster data for the Johnson SML Series is impressive, with standard EB Series thrusters using transformer oil BS148, typically Shell diala ‘B’. The approximate operating times are efficient, with brake release occurring in just 0.1 seconds and brake set times ranging from 0.25 to 0.5 seconds, depending on size and brake spring load. Alternative thrusters, such as Eldro/Elhy/Elco to DIN 15430 and DC Custom, are also available, ensuring compatibility with various systems and requirements.

Designed to accommodate both metric and imperial standards, the Johnson SML Series Thruster Drum Brakes offer dimensions in accordance with DIN standard code DL and A.I.S.E. standard code SMLA. Non-standard drum sizes and base fixings can also be provided to suit unique installation needs. With a comprehensive range of brake models, drum diameters, thruster model ranges, torque ranges, and weights, the Johnson SML Series is equipped to deliver exceptional performance and reliability in demanding industrial environments.
