A brand new Double Drum Hoist has just recently left Qualter Hall, bound for a silver mine in Morocco.
Qualter Hall secured the contract, awarded by Managem / SMI Casablanca, for the design, manufacture, supply, supervision of installation and commissioning of one 175kW Double Drum Hoist, complete with DC Motor, in December 2010. The Hoist weighs approximately 15 tonnes, with a diameter of 1600mm it has a rope speed of 4 m/s and is designed to carry 8 tonnes at any one time.
It will be used to transport men and materials within the mineshaft of a silver ore mine in Morocco to a depth of 400 metres. One of the drums is clutched so that the hoist can operate at different levels in the mine.
The Hoist is to be installed at the Imiter mine, situated in central Morocco, which provides enough ore to produce around 200 tonnes of silver each year. The mine is the largest silver mine in Africa and the ninth largest in the world.
Earlier this month, representatives of Managem visited Qualter Hall, for the final stages of testing. As a result, the Hoist has now been given a full nod of approval and is currently en route to Morocco, due to arrive in Morocco in December. Two engineers from Qualter Hall are scheduled to follow on in the new year for the installation, testing and final commissioning stage, expected to last four weeks and due to be completed by March 2012.
Says, George Orton, Managing Director, Qualter Hall: 'While over more recent decades, Qualter Hall has diversified its core engineering skills, the company has a heritage in servicing the deep mining industry that goes back over 150 years, so we are always delighted to have the opportunity to take on work that falls into this specific area of expertise.'
