Hydraulic cylinders for mining
Cylinders for mining machinery and equipment
Silvio Fossa designs and manufactures custom hydraulic cylinders for mining. Documented applications include mast raising, stabilization, drilling feed, boom movement, bed lifting and truck damping. Examples also include long-stroke and telescopic cylinders and rotary distributors.
These figures describe individual projects, not a standard range. Dimensions and performance are defined for each application. Multiple dimensions refer to the values listed for each example.
