This component is made of nodular cast iron and conforms to FEM 9.66/86. The wire rope passes through a tapered socket and wraps around a wedge. The tension on the wire rope caused by lifting of a load forces the wire rope and wedge into the socket creating a positive mechanical termination, eliminating the need for wire rope clips. Once set, the rope is secure in the loaded and unloaded condition.
All 31-Series hoists are fitted with either a mechanical or an electronic overload protection device. CSS’s “safe-load” unit is available as an option to monitor the load spectrum.
As an option, both hoist and trolley drives can be operated by means of a frequency converter. Acceleration and deceleration can each be adjusted so that swinging of the load, a known source of accidents, is largely eliminated. The high quality 4-pole motors are also suitable for over speed drive with reduced load.
The 3 stage reduction unit is comprised of a self contained cast iron housing with heat treated, alloy steel, helical gears in oil bath. All gear shafts are supported on antifriction bearings. The gearbox is rated to minimum design group of 2m/M5.
The DC rectified disc brake is an integral part of the hoist motor and is activated when the power to the hoist is terminated. The asbestos free brake linings are designed for 1 million brake operations. Under normal duty this brake is considered maintenance free requiring only inspection in accordance with local regulations.
The wire rope hoist is equipped with a heavy duty two speed pole changing squirrel cage motor that is fan cooled and designed for a minimum 2m/M5 duty cycle. The motor conforms to IP54 with class “F” insulation and has provision for thermal overloads.
The hook block sheaves are made of heavy cast iron with machined grooves rotating on sealed and lubricated for life ball bearings and are enclosed in protective guards. The hook complete with latch is forged from high strength steel and rotates on a thrust bearing. The hook complies with DIN 15 400.
The limit switches are safety features that control over hoisting and over lowering by disconnecting power to the hoist motor. The switches are adjustable for your specific requirement. The device consists of two high-precision, slow-brake micro switches acting on the auxiliary circuit of the hoist motor control device.
The drum is made from a steel tube with precision-machined grooves that properly support the hoisting wire rope to ensure maximum wire rope life. Each end is supported by bearings housed in rugged steel end plates. The drum is designed to conform to ISO 4308/1 and FEM 9.66 1/86.
The wire rope guide is a mechanical device which provides constant pressure on the wire rope to ensure a positive engagement with the drum groove. This prevents overlapping of the wire rope and promotes longer wire rope lifetime. A unique two-part system is designed for easy maintenance and durability.
Electrical controls (contactors, relays, etc.) are operated with a push button pendant station or a radio remote control unit. Inside the cabinet, you will find that every circuit has automatic fuses and all cables and components are clearly marked for easy identification. Each cable is connected directly to the external components.
The wheels are permanently lubricated and driven by a pole change motor. The motor is specially designed to give soft start and the ration between creep speed and maximum speed is 1:4. Minimum two of the wheels are always motorized.
