摘要： A work vehicle includes a cabin to cover an operator's seat on a traveling body. A cabin frame that constitutes a framework of the cabin includes a pair of left and right front pillars, a pair of left and right rear pillars, a front beam, a rear beam, and side beams. The front beam couples upper end portions of the front pillars to each other. The rear beam couples upper end portions of the rear pillars to each other. Each of the side beams couples to each other upper end portions of each of the front pillars and each of the rear pillars that stand at a front and rear. The rear beam is formed to have a U-shaped cross-section by presswork of a metal plate material.

摘要： An intelligent work vehicle preheating system includes an electric drive subsystem containing a battery pack, a hydraulic subsystem containing a first hydraulic fluid (HF) heating device, and a first HF temperature sensor. A memory stores a first minimum target temperature at or above which a first hydraulic fluid body contained in the hydraulic subsystem is desirably maintained. A controller architecture selectively places the intelligent work vehicle preheating system in an off-duty preheat mode when the electric drive subsystem is connected to an external power supply utilized to charge the battery pack. The controller architecture further controls the HF heating device to heat the first hydraulic fluid body when (i) the intelligent work vehicle preheating system is placed in the off-duty preheat mode, and (ii) the current temperature of the first hydraulic fluid body is less than the first minimum target temperature.

摘要： To provide a pipe member being able to reduce the vibration applied and improve its durability. A pipe member to be installed on the body of a construction machine has an outer main pipe and an inner auxiliary pipe inserted into the outer main pipe. An outer diameter of the inner auxiliary pipe is formed smaller than an inner diameter of the outer main pipe. The inner auxiliary pipe has a securing part secured on the outer main pipe and at least one of end parts of the inner auxiliary pipe is a free end without being secured on the outer main pipe.

摘要： An operator cabin may include a frame; a seat assembly supported by the frame; and one or more operator controls to control one or more components of a pipelayer machine, the operator controls being supported by the frame. The frame includes a front surface; a rear surface opposite the front surface; a first lateral surface; and a second lateral surface opposite the first lateral surface. The front surface may comprise a first front support structure and a second front support structure opposite the first front support structure. The rear surface may comprise a first rear support structure and a second rear support structure opposite the first rear support structure. A first distance between the first rear support structure and the second rear support structure may exceed a second distance between the first front support structure and the second front support structure.

摘要： A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a hydraulic actuator that drives driven parts including the lower traveling body and the upper turning body, a main pump that supplies hydraulic oil to the hydraulic actuators, a pump motor that drives the main pump, and a power storage device that supplies electric power to the pump motor. When the charging cable is connected to the charging port during the operation of the shovel, the shovel causes the hydraulic actuators to shift to the inoperable state. When the charging cable is connected to the charging port, the shovel does not start the pump motor even if an input for starting the pump motor is received from a user.
