New Putzmeister MINELIFT 4 Scissor Lift Platform for Mining To continue optimizing logistics of underground mining operations, Putzmeister has developed the MINELIFT 4 scissor lift platform. With a lifting height of 13 ft (4 m) and a 4 ton (3.63 tonne) capacity, the equipment provides a mobile and secure working platform for load and personnel lifting in under- ground mining and can also be set up for all kinds of installa- tions, such as piping and ventilation. In this way, MINELIFT 4 is adaptable to customers’ needs. MINELIFT 4 is available in a configuration setup for the installation of water, air, drainage, and tailing pipes in under- ground mining. It incorporates a drop-wing platform extension that expands the wide lateral by 28 in. (700 mm), providing a work surface total of 134 x 100 in. (3400 x 2550 mm). The high load capacity crane allows pipes to be lifted in an easy and safe way. For mounting, MINELIFT 4 incorporates a pipe handling system with two independent telescopic arms, designed for pipes from 4 to 8 in. (100 to 200 mm) and with load capacities of 661 lb (300 kg) each. In this way, MINE- LIFT 4 facilitates safe and efficient operation during pipe installation in underground mining. For ease of operation in ventilator mounting, MINELIFT 4 is available with an auxiliary lift platform that provides a load capacity of 5512 lb (2500 kg) and lifts up to 43 in. (1100 mm) from the main platform. By incorporating this optional equip- 56 Shotcrete • Winter 2015
