Bulldozers
BEML manufactures wide variety of
bulldozers with flywheel horsepower 66HP, 90HP, 165HP, 180HP, 230HP,
410HP and 770HP. Bulldozers are important engineering products which are
used for various mining operations. Hydraulic system plays a vital role
in these giant equipments, particularly in the systems like the
converter, the power shift transmission, steering, braking, work
attachment and ripper attachment.
The hydraulic system used in a bulldozer is comparatively simple in
nature when compared to the complexity of excavator hydraulics. Pumps
used in this system are of external gear type, which are preferred for
it's low cost and ruggedness. Two separate modules of a tandem pump are
used to power the blade circuit and ripper circuit individually. |
