Applications

  • Portal Cranes / Ship loading

    The Port Crane industry requires many brake systems on the Crane Hoists and the Drive systems that move the crane along the rail. In addition to the brake systems, a method of clamping the rails is required so that no movement occurs in the event of high wind forces. On hoists, the safest operation is with a dual braking method. The brakes should be mounted to the high-speed side of the gearbox and directly to the cable drum on the low speed side of the gearbox in case of a broken shaft or gears.

  • Oil Industry

    Johnson Industries 6800 Series Disc Brakes on 84" Diameter Brake Discs

    Four of Model 68HHH dual actuator, spring applied / hydraulically released calliper disc brakes mounted to 84.0″ Diameter Brake Discs on a 4600HP Drawworks System. This model has an impressive 95,000 lbs [422kN] of clamping force per brake.

    The oil industry has unique applications for both, on-shore and offshore equipment. The Drawworks equipment is essentially a winch system for creating a series of pipe connections to drill into reservoirs of oil beneath the Earth’s surface. The braking system requires an ever-increasing amount of brake torque as the load increases due to the depth drilled. The addition of each piece of drill pipe as the drill string reaches further into the drill hole, causes an increasing load until the desired depth is reached. For this applications
    brake systems require a cooling system, either through water-cooling or air ventilation at the brake disc. The brakes are typically either Hydraulic or Pneumatic versions.Oil-sm

  • Mining

    The mining sector braking requirements are vast. This sector utilizes Conveyor Systems, Grinding Mills, Stackers / Reclaimers, Mine Hoists, and various other types of rotating drive equipment, which require Brake Systems. The brake systems can be extremely large at up to 1 Million pounds [4448 kN] of clamping force, and there are also modest sized brakes, which start at 2900 pounds [12.8 kN] of clamping force. The braking systems can range from simple on/off emergency braking units to the more complex PLC controlled systems, which have several modes of braking response due to the feedback of changing conditions.

  • Lumber Industry

    Lumber-lg

    In the wood handling crane sector, high duty cycle industrial brakes are required. The high duty cycle is required due to the quick agile crane operations for loading and systematically processing logs. In high duty cycle applications, achieving quick brake response times and multiple stops in succession are important.

    Log handling crane fitted with 58HHH toggle lever high duty cycle caliper disc brakes Hydraulic Caliper Disc Brakes and an HU022SR hydraulic Power Unit. The log-handling crane requires less land (work envelope), and is more environmentally friendly when compared to identical raw log handling methods.

  • Coal Handling

    Stacker Relaimer

    In the material handling industry, Stackers, Reclaimers, and Combination Stacker Reclaimers are utilized to move or re-position bulk materials such as coal and iron ore, in an efficient manner. The equipment is typically rail mounted providing movement in one direction and also has a boom, which can be raised or lowered for more accurate bulk material positioning. The typical Stacker is loaded via a dump truck or tractor and has a conveyor belt which moves material to another location. As the Stacker moves along the rails, it creates a systematic pile of Bulk Material for further processing. The dichotomy to the Stacker is the Reclaimer which has buckets that can scoop up the material and reposition in a different location via the conveyor belt. The braking options for a Sacker or Reclaimer can include, high speed brakes on the conveyors / bucket system, and Rail Clamps or Wheel Brakes for stopping or holding the system in a static position when high winds arise.

  • Steel Industry

    The steel industry typically uses brake systems, which can take advantage of existing power on site, and electric type brakes, which tend to work better within high-temperature environments than hydraulic and pneumatic types. Quite often older steel mills will have DC (Direct Current) Power on site, which lends itself to Johnson Magnetic Disc and Drum Brake systems. The other typical types of brakes are AC (Alternating Current) thruster drum brakes, which can be controlled better than DC magnet brakes for applications where the Brake Torque must be modulated. Johnson DC magnet brakes work well for static and dynamic holding as the brake torque is adjustable

  • Ski Lift / Ropeway Industry

    The ski lift / ropeway industry requires unique brake systems as the variables are typically different for each project. The length of the ski hill dictates the length of the Ski Lift and thus the capacity of the equipment. The brake systems require gradual soft stopping to avoid having people fall down or become injured. The recent designs we have provided include the soft stop on Ski Chair Lifts to avoid excess swing in the Chairs.

    Drive Systems

    Johnson DS Series Caliper Disc Brakes

    Our brakes can be utilized for dynamic stopping, emergency stop, or both. Johnson calliper disc brakes can be electric, air, or hydraulic. The stopping time can be adjusted to suit any application where a gentle soft stop is required.
