摘要： A fork lift truck includes a body, a drive mechanism supported on the body for effecting movement of the body, and a fork carrying assembly carrying forks which can be moved in height between a lowered position and desired raised positions. A tilt cylinder is provided for tilting the forks through a fork tilt range. The truck further includes a pressure sensor capable of generating signals indicative of the weight of a load on the forks, a fork tilt position sensor capable of being activated when the forks are tilted to extremes of the fork tilt range, and a controller. The controller is coupled to the drive mechanism, the pressure sensor and the fork tilt position sensor. It causes the drive mechanism to effect movement of the body up to a first maximum speed when at least one of the pressure sensor generates a signal indicative of a load on the forks having a weight above a predetermined value and the tilt position sensor is activated, and causes the drive mechanism to effect movement of the body up to a second maximum speed which is greater than the first maximum speed when the pressure sensor generates a signal indicative of no load or a load on the forks having a weight below the predetermined value and the tilt position sensor is inactivated. The lowering speed of the forks can also or alternatively be increased under the same operating conditions.
摘要翻译：叉车包括主体，支撑在主体上用于实现主体运动的驱动机构，以及承载组件的叉子承载组件，叉组件能够在降低位置和期望的升高位置之间移动高度。倾斜气缸用于通过叉倾斜范围倾斜叉。叉车还包括压力传感器，其能够产生指示叉子上的负载的重量的信号;当叉子倾斜到叉倾斜范围的极端时能够激活的叉倾斜位置传感器以及控制器。控制器耦合到驱动机构，压力传感器和叉倾斜位置传感器。当压力传感器中的至少一个产生指示叉子上的负载的信号，其重量高于预定值并且倾斜位置传感器被激活时，使得驱动机构使身体的运动达到第一最大速度，并且当所述压力传感器产生指示没有负载的信号或具有重量低于所述预定值的货叉的负载时，所述驱动机构使所述主体的运动达到大于所述第一最大速度的第二最大速度，倾斜位置传感器失效。在相同的操作条件下，叉的降低速度也可以或者可选地增加。

摘要： A work vehicle is provided comprising: a main frame including an engine compartment; an engine located in the engine compartment; and a cooling system comprising a rotating fan apparatus and a cooling assembly. The cooling assembly may comprise a heat exchanger for transferring energy in the form of heat from a coolant fluid to air and a filter apparatus positioned adjacent an engine-compartment side of the heat exchanger. The air may be moved through the heat exchanger by the fan apparatus. The filter apparatus may filter the air before the air passes through the heat exchanger. The filter apparatus may comprise filter structure and a suction device for removing debris from the filter structure. The suction device preferably expels the debris outside of the engine compartment.

摘要： A personnel carrying vehicle comprising a self propelled, steerable body, a telescoping mast attached to and extending upwardly from said body, and a personnel compartment attached to the mast and provided with a rail member that extends from the mast and around the sides. A pair of gate members, which are pivotally attached to the rail member and to the floor of the compartment, are movable from a closed position to an open position wherein said gate members extend into the compartment. The mast extends upwardly and forwardly of the body at an angle of approximately five degrees to the top of the rail; this provides the operator with unobstructed access to anything above the top edge of the rail, and the forward tilt of the mast enlarges the upper portion of the compartment, near the waist of the operator, thus accommodating the operator comfortably without increasing the length of the vehicle; it also causes the center of gravity of the vehicle to move forward, toward the center of the vehicle, as the compartment is raised. The vehicle is driven by electric motors which are located under the operator compartment and attached to the drive wheels through gear trains to permit the floor of the compartment to be positioned as close to the ground level as possible. Control handles are mounted within the personnel compartment, with one handle controlling steering and the other handle controlling traction. Sensors ensure the operator's hands are on both control handles and both feet are properly positioned on the floor before the vehicle can be moved or the platform raised; this ensures a four point stance, providing for operator stability and that the operator's hands and feet are within the operator's compartment anytime the vehicle is being moved or during lifting or lowering operations. Gate interlock switches are provided to restrict or prevent travel of the vehicle under certain conditions. A load deck is provided on the body of the vehicle on the opposite side of the mast from the personnel compartment. Also, a load tray may be mounted to the telescoping mast to move vertically with the compartment. Rail guides may be mounted to the outside of the vehicle to facilitate entry into and operations within narrow aisles.
