Abstract
A slasher saw system connectable to a source of hydraulic power which requires only three hydraulic lines for power and operation. First, a pressure/power hydraulic line is actuated to turn the saw on and bring the saw down to cut through a stack of timber. Second, the hydraulic pressure/power to bring the saw down is actually provided via back-pressure from a return line returning hydraulic fluid to the source of hydraulic power from the saw. Third, a separate line is used to power the hydraulic cylinder used to raise the saw arm again.
Claims16
A hydraulically powered slasher saw system adapted for connection by hydraulic lines to a source of hydraulic power, comprising:
- a saw blade actuated by a saw blade motor, which saw blade is raised in order to position a load of wood for cutting and lowered to cut through said load of wood;
- a first hydraulic fluid input line connectable between said source of hydraulic power and the saw blade motor for powering said saw motor;
- a second hydraulic fluid output line connectable between said saw blade motor and said source of hydraulic power for recirculating hydraulic fluid from said saw blade motor to said source of hydraulic power;
- a third hydraulic fluid line connectable between said source of hydraulic power and a mechanism for raising the saw blade via hydraulic fluid input from said first hydraulic fluid line;
- and
- a fourth hydraulic fluid line connected by a “T” juncture to said second hydraulic fluid output line and running between said “T” juncture and a mechanism for lowering said saw blade via hydraulic fluid input from said hydraulic fluid output line.
