Abstract
A construction machine includes: an engine driving at least one hydraulic pump configured to supply operating oil to a hydraulic actuator; an exhaust adjustment mechanism adjusting a flow rate of exhaust from the engine; and a control device controlling the exhaust adjustment mechanism. The control device determines whether or not a first downhill traveling condition and/or a second downhill traveling condition are/is satisfied. When at least one of the first downhill traveling condition and the second downhill traveling condition is satisfied, the control device controls the exhaust adjustment mechanism such that the exhaust adjustment mechanism executes exhaust brake.
Claims7
A construction machine comprising:
- an engine driving at least one hydraulic pump configured to supply operating oil to a hydraulic actuator;
- an exhaust adjustment mechanism adjusting a flow rate of exhaust from the engine;
- and
- a control device controlling the exhaust adjustment mechanism, wherein:
- the control device determines whether or not a first downhill traveling condition and/or a second downhill traveling condition are/is satisfied, the first downhill traveling condition being a condition in which an actual revolution speed of engine is a set revolution speed or more and a load factor of the engine is a set rate or less, the second downhill traveling condition being a condition in which when the engine is coupled to a wheel through a transmission, an actual vehicle speed is not less than an allowable vehicle speed of a vehicle speed mode selected by an operator;
- and
- the control device controls the exhaust adjustment mechanism such that the exhaust adjustment mechanism executes exhaust brake when at least one of the first downhill traveling condition and the second downhill traveling condition is satisfied.
