load braking system in wire rope hoists

  • Hoists must have two braking functions, Holding and Controlled Lowering. The holding brake maintains the load in a stationary position when the load is suspended and no power is applied to the motor. The controlled braking function must ensure that the load does not overhaul or overspeed the motor when the load is being lowered.

  • What is a mechanical load brake, and why does it matter to me

    The mechanical load brake is a key component of crane safety. It serves as a secondary braking mechanism of the crane hoist, controlling the lowering speeds of rated loads and preventing loads from free falling. As an alternative, some cranes have an electrical load brake, which serves the same function.

  • Yale Cable King Electric Wire Rope Hoist 1/2 Ton to 35 Ton Capacity. Ideal for use in both standard industrial and hazardous environments, the Cable King is one of the most customizable hoists available on the market. Mechanical load brake is available on this model.

  • Yale Y80 Wire Rope Hoist Electric Wire Rope Hoists The heavy-duty Y80 hoist is available as a single- or double-reeved unit and features a powerful drive motor and reliable dual braking system. Yale Y80 Wire Rope Hoists are ideally suited for virtually any lifting application.

  • These hoists are quieter and more stable than electric chain hoists. Use the handheld control to effortlessly lift your load. Electromagnetic brake provides quick, secure braking and works when there is no power. Mechanical brake stops the load and holds it in place when you're not lifting.

  • This electric wire rope hoist comes standard with an industrial wireless remote control, which is waterproof, shockproof, and can be operated from 100 feet away. It also features a safety key and emergency stop button.

  • A Better Alternative to Crane Hoist Mechanical Load Brakes

    The load brake should also be able to hold the load on its own. The basic principle of a crane hoist’s mechanical load brake is the mechanical conversion (into heat, through friction) of the kinetic energy produced by the descent of the load. Heat is dissipated from the friction surfaces to the oil in the gear case and then to the atmosphere.

  • The purpose of a “load brake in a hoist application is to keep the suspended load from falling without power to the hoist and independent of the motor brake.” When the load is being lowered the clutch locks stopping the load brake system from rotating. As soon as the motor stops driving the load, or the load travels faster than the motor

  • Hoist brakes are essential for crane safety. Hoist brakes are an essential safety feature of overhead cranes. Designed to hold a load when the hoist motor is not running, these brakes reduce the risk of falling loads that could result in injury and property damage.

    As soon as the current is cut off the brake spring (9) presses the brake disc (12) against the cover and the brake is applied. The braking torque is 100% above the motor torque at the rated load. The maintenance and adjustment of the brake us very simple due to system and can be done without removing any part.
