Size of a Roadheader
The road header is a machine used for tunneling. It comes with a 
drum mounted on the base which is fitted with a cutting head. As it turns, rock or ore is excavated. The machine is used mainly for mining and in railroads.
SLB-350S Road Header Sizes
The machine is 18m long and 4.8m high. The cylinder width is 3.4m (3.2m) and the weight is 120 tons. The cutting motor is 350/350kW-4/6P and the under cut is 0.45m. The maximum cutting width is 8.8m. The maximum cutting height is 8.8m. The machine is designed for excavating soft and medium hard rocks.
SLB-300S Road Header Specs
The SLB-300S is 13.5m long and 4.8m high. This road header is 3.4m (3.2m) wide with the crawler and it weighs 90 tons. The maximum cutting edge width is 8.3m and the maximum cutting height is 8.8m. The under cut is 0.45m and the cutting motor is 300/200kW-4/6P.
The SLB-300S is designed for use in different geological conditions. It can be used on rocks up to 100MPa. The machine also has a variable drum rotation speed. This means it can be used in unique geological settings.
