The power of hydraulics systems is recognized in most fields, from construction to aviation. The ability to use the force multiplier of pistons moving against incompressible liquid means that hydraulics make for a great power-to-weight ratio, using well-understood and relatively easy-to-maintain systems.
Nowhere is this more apparent than in the excavation industry. The entire class of earthmovers known as “bulldozers” (or “dozers,” for short) is built around hydraulic systems providing the majority of the control and force for the machine.
Bulldozers utilize two or three sets of main hydraulic cylinders, depending on options and upgrades on the bulldozer. The initial sets of cylinders are known as the “main” and “tilt” cylinders. The main cylinder on a bulldozer is responsible for elevating and lowering the blade on the front of the bulldozer. A bulldozer typically has two lift cylinders. The tilt cylinder tilts the blade backward and forward, allowing a fine degree of control for earthmoving and removal. Most dozer models also incorporate two tilt cylinders as well, except for “power angle” dozers, which will utilize only one.
Power angle dozers also incorporate an entirely different set of cylinders, known as “angle” cylinders. These provide the blade with the ability to move left to right, providing the maximum amount of control for manipulation of the blade. Dozers may also incorporate a fourth set of cylinders if they are equipped with a “ripper,” a two-piece claw used to break up soil or tear down structures.
Hydraulic systems are responsible for the majority of the workload provided by your bulldozer and will provide years of top-notch power when maintained and serviced regularly. Texas Hydrostatics are first-class bulldozer and hydraulic systems experts. For all of your dozer-related questions, contact them to explore the possibilities.
