A notch 41, which is formed on a land 31 that, in a main spool 30, blocks a reach-in side actuator port A from communicating with a second passage T, comprises a first notch and a second notch. The first notch comprises a first region that has a semi-circular shape in the plan view and in which the area of an opening between a valve body 40 and the land 31 becomes gradually larger, and a second region that is connected to the first region and in which the area of an opening between the valve body 40 and the land 31 is constant, and the second notch comprises a third region that has a semi-circular shape in the plan view and in which the area of the opening between the valve body 40 and the land 31 gradually becomes larger, and a fourth region that is connected to the third region and in which the area of the opening between the valve body 40 and the land 31 is constant.

An industrial truck having at least one hydraulic mast lift cylinder, which is connected to a hydraulic block via a hydraulic arrangement that limits a lowering speed of the mast lift cylinder. The hydraulic arrangement is formed to limit the lowering speed in a load-dependent manner to at least two maximum values. A first maximum value is given for the lowering speed at the nominal load while a second maximum value is given for the lowering speed with a load that is smaller than the nominal load, i.e., wherein the first maximum value is less than the second maximum value.

A fluid pressure control device includes a neutral passage, a control valve provided in the neutral passage, a first supply passage, and a discharge passage, the control valve has, a switching valve configured to control a flow of a working fluid to the discharge passage from the first actuator in accordance with a pressure in a pilot chamber to which a part of the working fluid supplied from the first supply passage to the first actuator is led, and a throttle portion configured to throttle the flow of the working fluid supplied to the first actuator from the first supply passage, and the pressure on an upstream side of the throttle portion is led to the pilot chamber.

A housing for a hydraulic actuator unit of a pallet truck is disclosed. The housing includes a lift motor mount for mounting a lift motor to the housing and a pump mount for mounting a hydraulic pump to the housing, and couples the pump to the lift motor when each are mounted. The housing includes a hydraulic cylinder with a cylinder rod, which is positioned based on the fluid level in the hydraulic cylinder; a reservoir to store fluid for actuation of the cylinder rod; and one or more fluid galleries that extend, internal to the housing, among the fluid reservoir, the pump mount, and the hydraulic cylinder. A traction motor mount mounts the traction motor, which is coupled to a steering unit of the pallet truck and controls actuation of a traction wheel of the pallet truck when the traction motor is mounted to the traction motor mount.
