摘要： A walking-type snow removal machine comprises a snow removing member provided at a front part of a body frame for pushing snow forward, and crawler belts provided on right and left sides of the body frame. The body frame carries thereon an electric motor and a battery. The electric motor drives right and left drive wheels to drive the crawler belts. The electric motor generates little noise as compared with an engine, and contributes to downsizing of the snow removal machine. The battery supplies electrical power to the electric motor.

摘要： A snow removal machine propelled by crawler belts trained around drive wheels and driven wheels is provided. The snow removal machine has a scraper confronting the outer periphery of the driven wheel so as to remove snow adhering to and accumulating on the outer periphery during snow removing operation. It prevents increase in tension of the crawler belt due to the increased diameter of the driven wheel in appearance that might otherwise be caused by snow adhering to the outer periphery.

摘要： A self-propelled snow remover has a machine body, a snow-removing implement mounted to a front part of the machine body for undergoing rolling and vertical movement relative to the machine body, and an operating unit mounted to a rear part of the machine body. An alignment operating member is mounted to the operating unit for rolling and vertically moving the snow-removing implement. The alignment operating member is disposed on one of opposite sides of a widthwise central line of the machine body. A return operating member is mounted to the operating unit for automatically returning the snow-removing implement to a predetermined reference position. The return operating member is disposed proximate to the alignment operating member at a position closer to the widthwise central line of the machine body than the alignment operating member and further towards the rear part of the machine body than the alignment operating member.

摘要： A walk-behind electric working machine has a frame, an electric motor mounted on the frame, and a handle support section mounted on the frame, the handle support section having a pair of electrical terminals. A handle post has a first end portion for removable connection to the handle support section, a second end portion, and an electrical terminal disposed on an outer peripheral surface of the first end portion for electrical connection with the electrical terminals of the handle support section when the first end portion of the handle post is connected to the handle support section. A handle is removably mounted on the second end portion of the handle post and has handle portions. Grip members are mounted on the respective handle portions and are configured to be gripped by respective hands of an operator. An operation button controls power to operate the electric motor when the electrical terminal of the handle post is electrically connected to the electrical terminals of the handle support section.

摘要： In a travel control method for an electric vehicle having first and second electric motors for driving respective first and second driven wheels, a speed of each of the first and second electric motors is calculated. The speed of the first electric motor is reduced to equal the speed of the second electric motor when the speed of the first electric motor is higher than the speed of the second electric motor. Reduction of the speed of the first electric motor is not carried out when a first condition, in which a difference between the speeds of the first and second electric motors is below a first preselected threshold value, and a second condition, in which the speed of the first electric motor is below a second preselected threshold value identical or substantially equal to a low speed range of the electric vehicle, are met.

摘要： A travel control method of an electric vehicle wherein to raise the straight-line driveability of the electric vehicle speed-reduction control is carried out so that the speed of an electric motor rotating at a higher speed is lowered to match the speed of an electric motor at a lower speed. This speed-reduction control is executed when the speed of the motor at the higher speed is above a preset threshold value. The time taken to reach a predetermined threshold value from immediately after starting is short, and the electric vehicle reaches the desired speed rapidly after moving off.

摘要： An electric vehicle in which left and right electric motors respectively driving left and right transporting parts are controlled by a control part and particular turning control of the electric motors is carried out when the electric vehicle turns. The electric vehicle has a left and right pair of push-button turn switches. When one of the turn switches is operated, the control part selects a pattern from multiple preset deceleration patterns and decelerates the motor on the inside of the turn, which corresponds to the turn switch being operated, on the basis of this deceleration pattern. The electric vehicle makes turns and returns to straight-line travel optimally and smoothly and can be operated easily by an operator with no skill or experience.
