High-performance electric wire rope hoists

Becker Mining SA’s Kito RX electric wire rope hoists – launched in Africa two years ago – play a critical role in many industries, including mining, construction, shipbuilding, food, beverage and pharmaceutical processing, manufac turing and general industry, as well as in chemical and pet rochemical plants and the wind power sector. “The addition of Kito electric wire rope hoists to our ex tensive range of Kito manual and electric chain hoists and lever hoists has been a success,” says Rick Jacobs, Senior General Manager (SGM) for Consumables, Becker Mining South Africa – distributors of the Kito range in Africa since 1986. “Our customers rely on dependable and safe liŽing equipment, supported by the assurance of quality specifica tions, as well as a reliable support service. “Kito RX electric wire rope hoists have been developed with a robust design and advanced technology for dependa ble operation and extended service life in tough conditions. Typical applications are in production plants, plant engi neering, production lines and workshops, as well as ship building and general maintenance procedures. “The flexible hoists are adaptable for use with existing cranes and machinery and all components are easily acces sible for ease of maintenance.” Technical features The Kito RX range, with liŽing capacities between 1 000 kg and 50 000 kg, is available from Becker Mining in units with two or four rope strands, reeving 2/1, 4/1 and 4/2. The hoists have liŽing speeds from 1.5 m/min to 12 m/min, with the op tion of single-speed, two-speed and frequency-control. Features include 380-440 V / 50-60 Hz / 3 phase, Insula tion Class: IP55 (standard) or IP66 (optional) and a control voltage of 42 V, 110 V, 24 V, 48 V or 230 V (optional). The hoists are powered by a three-phase asynchronous motor or the option of a sliding anchor motor. A planetary gearbox en sures optimum power transmission between the hoist motor and rope drum.

tion, where driven wheels are connected directly to the self-braking gear motor, ensures e”icient power transmis sion between the running wheels and the trolley rail. This design also contributes to reduced wear, low maintenance requirements and extended service life. The standard headroom monorail design of the trolley enables the hoist to operate directly under and parallel with the crane or runway beam. The hoist is directly connected to the trolley and all components are easily accessible for maintenance. Hoists in the Kito RX range include a foot mounted hoist without a trolley, designed for liŽing capacities from 1 000 kg to 50 000 kg and a hoist with a standard headroom mono rail trolley, for capacities from 1 000 kg to 32 000 kg. Double girder trolleys are suitable for capacities from 1 000 kg up to 32 000 kg, either supported or suspended, version S2-S4. This range is available only in supported execution for liŽ- ing higher capacities from 20 000 to 50 000 kg, Double hoist units are also supplied, with capacities up to 100 000 kg. Becker Mining also supplies a full range of Kito accesso ries to enhance the performance of Kito hoists. To ensure hoists are maintained in good condition and always operate safely, it is recommended that equipment is tested regularly at Becker Mining SA’s workshops, or any certified repair centre. Becker Mining SA is committed to the highest standards in quality and safety. It o”ers technical advisory, repair, test and backup services throughout Africa. A specialised con sulting, training and support facility supports optimum op erating e”iciency across a range of equipment and safety for workers. Becker Mining also supplies high-performance fit-for-pur pose energy distribution, automation and communication solutions, and more.

For enhanced safety, an electromagnetic disc brake acts directly on the rotor shaŽ for e”ective braking force. Electronic overload protection, with two adjustable levels, o”ers protection to the hoist and all its components from overloading (Performance Level C). There is also integrated overheating protec tion for the motor. The rope guide is another notable design feature. It consists of two parts – the guide ring and tension spring. The tension spring ensures the rope lies correctly in the drum groove, while the guide ring always maintains the rope in the correct position, preventing it from coming o” the drum groove. By moving the guide ring along the drum, limit switches are activated for the highest and lowest hook positions. The double-girder trolley is equipped with double-flange wheels, all with high-quality ball bearings. This construc
