INCO - Mining Hoists and Complete Equipment for Vertical Mining

INCO engineering was established in 1994 as a successor of the company CKD Praha, and specialises in the field of hoisting machines and equipment for deep mining. One of the first machines supplied was a steam driven mine hoist in 1905.

Since its inception, more than 620 mining hoists of various types and sizes have been delivered. In addition to supplies of mine hoists for Czech and Slovak mines, we have delivered 90 hoists to customers in Poland, and a number of hoists to Russia, Germany, and Spain.

PRODUCTION PLAN - HOISTING MACHINES AND EQUIPMENT

Our extensive production plan includes both mining hoists with friction disks and drum hoists of various constructions and performances, as well as individual systems, such as DC and AC drives, thyristor converters, digital drive regulators, microprocessor controlling systems, low / high voltage distributors, control panels, air-conditioned cabins and an electro-hydraulic brake system range from HR5K to HR11K. We also provide electro-pneumatic brake systems and disc brake units HPB 170 and HPB 200.

Our modern mine hoists come in various types and sizes, an example is a twin-motor four-rope mining hoist with a frictional disc. Modern mine hoist designs include anti-friction bearings, modern structures of a frictional disc shell, hydraulic disc brakes, thyristor converter and digital drive regulation, Tribonik system for circulatory lubrication of anti-friction bearings, Frenomatic HR11K with regulation for constant retardation of safety braking, several microprocessor systems for control and safeguard of interconnected redundant nets ControlNet, digitalized machinist console equipped with a joystick control and a central system of visualization of operational and faulty conditions.

In addition to the above mentioned items, we supply mine signalling systems, winding pulleys, pushers, skips and cages, cart circuits, mine ventilators with frequency drive regulation and more. All items include full support, from the project assignment to turnkey delivery including installation, warranty (and post-warranty) service and supply of spare parts.

INNOVATION - BRAKE SYSTEM FRENOMATIC HR11K FOR WINDING MACHINES

We supply the electro-hydraulic brake system Frenomatic HR11K, with constant retardation of safety braking which applies the same amount of braking power in all operational situations - one of the patents of Jan Houdek, PHD, the executive director of INCO, and also Sistonik PR6K/B electro-pneumatic brake system, as well as the Tribonik system for automated bearing lubrication.

MINING HOISTS MODERNIZATION SERVICE

In addition to these supplies, the company provides modernizations and reconstructions of older mining hoists. The complete reconstructions and modernizations of mining hoists are completed by our highly experienced technicians and specialists.

ONLINE MINE HOIST MONITORING

INCO offers Transdatik monitoring system. This system has the ability to transfer information about individual systems of the machine with the aid of the Internet or GSM network to the service central of the company. The advantage of this system is that it allows for immediate action of the service personnel in the event of any abnormality.
