<p><P>PROBLEM TO BE SOLVED: To provide a construction vehicle capable of suppressing deterioration of pulling force during low speed traveling. <P>SOLUTION: The construction vehicle is provided with an engine, a main pump driven by the engine, a second travel motor driven by pressure oil delivered from the main pump, tires driven by driving force of the second travel motor, and a control part. In the control part, an engine speed, a capacity of the main pump, and a capacity of the second travel motor are controlled to control a vehicle speed and the pulling force. In the control part, in a low speed area wherein the vehicle speed is lower than a predetermined threshold, a maximum capacity of the second travel motor is increased as the vehicle speed is lower. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
