Tunnelling Machines
Susumo Engineering has launched a totally fresh set of Machines for Tunnelling Jobs. These consist of the whole range from simple Tractor Trolley Loading Bucket to Mucking Machines. Mucking Machine consists of an excavating arm and a conveyor. The arm scrapes the muck onto the conveyor. The conveyor carries the muck to a height of 2.25 mtr. Dumpers have to reverse and stand under the conveyor to collect the falling muck. The whole machine is self-propelled. All four wheels have independent power and all of them can be steered. This helps in taking gradients, uneven terrains and turning in small spaces. Tunnel Excavators is an excavator mounted on tyres. The excavating arm is specially designed. It has a long reach and can turn 360 degrees in very small micro-tunnels also. All its wheels are hydraulically driven hence it can take gradients. Being on tyres it travels faster than track-mounted excavators. It can pick-up muck from the front, turn 180 degrees and unload it onto trolleys or dumpers, etc., an ideal machine for small tunnels and mines. Trolley Loading Bucket is an entry-level machine, which loads tractor trolleys. The muck has to be scrapped onto the bucket manually. When it reaches a max capacity of 500 kg, the bucket is raised hydraulically. The whole load of muck is thus transported directly to the centre of the tractor trolley. This machine is self-propelled and works on single-phase electric supply. It mainly eliminates the lifting of muck by labour. It involves the least of hydraulics and is hence easy to operate and maintain. Site-Trucks are very low height machines, which can carry muck and pour it outside the tunnels. These are hydraulically powered 4-wheel drive machines. They can also be used to carry concrete.
