A processing plant in the platinum area has purchased the first wire rope hoist from a new range brought into the country by Becker Mining South Africa. To be used in maintenance procedures and the installation of new equipment in the plant, the 10t, 525 V with 25 m lift Kito RX will be supplied by Tech North, the company’s distributor in the Rustenburg region.
“The addition of wire rope hoists is an important addition to our extensive range of Kito lifting equipment which includes manual and electric chain hoists and lever hoists,” explains, senior general manager (SGM) for consumables, Becker Mining South Africa, Rick Jacobs.
“Our new Kito RX wire rope hoists have been developed with a robust design and advanced technology, for dependable operation and extended service life in tough conditions. These flexible hoists are adaptable for use in conjunction with existing cranes and machinery and all components are easily accessible for ease of maintenance.
“RX wire rope hoists are suitable for many industrial applications, including production plants, plant engineering, production lines and workshops, as well as ship building and maintenance.”
The Kito RX range, with lifting capacities between 1 000 kg and 50 000 kg, is available in units with two or four rope strands, reeving 2/1, 4/1 and 4/2. These hoists have lifting speeds from 1.5 m/min to 12 m/min, with the option of single-speed, two-speed, and frequency-control.
Features include 380 – 440 V / 50 – 60 Hz / 3 phases, insulation class: IP 55 (standard) or IP 66 (optional) and a control voltage of 42 V, 110 V, 24 V, 48 V or 230 V (optional). These hoists are powered by a three-phase asynchronous motor or the option of a sliding anchor motor. A planetary gearbox ensures optimum power transmission between the hoist motor and rope drum.
For enhanced safety, an electromagnetic disc brake acts directly on the rotor shaft for effective braking force. Electronic overload protection, with two adjustable levels, offers protection to the hoist and all its components from overloading (performance level C). There is also integrated overheating protection for the motor.
A notable design feature includes the rope guide that consists of two parts – the guide ring and tension spring. The tension spring ensures that the rope lies correctly in the drum groove, whilst the guide ring always maintains the rope in the correct position, preventing it from coming off 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 construction, where driven wheels are connected directly to the self-braking gear motor, ensures efficient power transmission between the running wheels and the trolley rail. This design also ensures extended service life, reduced wear and low maintenance requirements.
Trolley construction comprises a standard headroom monorail design that 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 ease of maintenance.
Hoists available in this range include a foot-mounted hoist without a trolley, designed for lifting capacities from 1 000 kg to 50 000 kg and a hoist with a standard headroom monorail trolley, for capacities from 1 000 kg to 32 000 kg. Double girder trolleys are suitable for capacities from 1 000kg up to 32 000 kg, either supported or suspended, version S2-S4.
Units are available only in supported execution, for capacities from 20,000 kg up to 25,000 kg two rope falls, and for capacities from 40 000 kg to 50 000 kg, four rope falls. Units are also supplied as a double hoist, with capacities up to 100 000 kg. The low headroom monorail hoist trolley is designed for capacities from 1 000 kg to 16 000 kg.
There are many options available to suit specific application requirements.
