DavyMarkham's first Peruvian contract is for $5.4 million
Sheffield-based heavy engineering company DavyMarkham has its first contract from Peru, a $5.4 million contract for the supply of two heavy duty mining hoists to Volcan Compañia Minera, the fourth largest producer of zinc and silver worldwide.
The order is for production and service hoists for Volcan's latest Pique Andaychagua mining project in the Yuauli province, some 150 km northeast of the Peruvian capital Lima, which will be designed for an estimated production rate of 4,000 tonnes per day from depths down to 970 m.
The new DavyMarkham hoists will contribute toward Volcan's ambitious production targets, while at the same time cementing the Sheffield concern's market status as a world leader in mine winder technology. The mechanical equipment will be based on a proven DM design supplied extensively to the global mining industry over the last 15 years.
Designed and produced in Sheffield, with the drums modelled using finite element analysis (FEA) software, the Volcan scope of supply includes a 3.66 m (12 ft) double drum production hoist, capable of hauling twin ore skips, and an 2.54 m (8' 4") single drum service hoist, equipped with a personnel carrying cage, with the latter also designed to undertake shaft sinking duties prior to operating in final production mode.
The service hoist will have a payload capacity of 2,400 kg, will operate to a shaft depth of 940 m and is scheduled for delivery this autumn. The larger production winch has a maximum payload of 9,000 kg, will operate to depths up to 970 m, and is due for commissioning next spring.
