A load sensitive ride system and method is disclosed for a vehicle with an implement movably attached by a boom cylinder. The system includes a payload weight measuring system that measures payload weight and generates a signal indicative of the payload weight, a ride control circuit that adjusts hydraulic flow to and from the boom cylinder; and a controller that receives the signal indicative of the payload weight, and sends compliance commands to adjust ride control compliance based on the signal indicative of the payload weight. The system can include a tire inflation system that adjusts tire pressure. The controller can send inflation commands to adjust tire pressure based on the signal indicative of the payload weight. The compliance commands can depend on the components and compliance adjustment methods of the ride control circuit.

An adjustable ride control circuit and method that includes a head valve that controls flow between a boom cylinder head intake and an accumulator, and a rod float valve that controls flow between a boom cylinder rod intake and tank, where the rod float valve is electronically adjustable and proportionally controls flow restriction. A controller controls ride control activation, and adjustment of the head and rod float valves. When ride control is activated, the head valve allows flow between the head intake and the accumulator, and the controller automatically adjusts the rod float valve. When ride control is deactivated, the head valve blocks flow between the head intake and the accumulator, and the rod float valve blocks flow between the rod intake and tank. An enable valve can control positioning of the head valve. A flow selector can select manual or automatic adjustment of the rod float valve.

A work machine includes a chassis, a boom coupled to the chassis, and a work implement coupled to the boom and movable relative to the chassis. In system may further include dynamic payload weighing system configured to measure the payload weight on the work implement. The system may also include an electrohydraulic system controller in communication with the dynamic payload weighing system and an electrohydraulic control valve electrically coupled to the electrohydraulic system controller and moveable to a plurality of weight-specific valve positions based on the measured payload weight on the implement.

A work machine that has a chassis, a payload section, a controller, a payload sensor in communication with the controller, and an orientation sensor that identifies the orientation of the work machine to the controller. The controller determines a center of gravity for the work machine considering a payload weight identified by the payload sensor and sends an alert when the location of the center of gravity and the orientation of the work machine create an unstable condition.

An actuator is connected to a frame and a boom arm to pivot the boom arm with respect to the frame. A spool valve directs fluid from a pump into a selected side of the actuator. A first anti-cavitation valve is fluidly positioned between the first end of the actuator and the reservoir to permit fluid flow from the reservoir to the first end of the actuator while the first anti-cavitation valve is open and inhibit fluid flow from the first end of the actuator to the reservoir. A second anti-cavitation valve is fluidly positioned between the second end of the actuator and the reservoir to permit fluid flow from the reservoir to the second end of the actuator while the second anti-cavitation valve is open and inhibit fluid flow from the second end of the actuator to the reservoir.

A control system for a material handling vehicle has a boom arm connected to a vehicle frame for rotation about the vehicle frame. An actuator is connected to the vehicle frame and the boom arm to cause the boom arm to rotate about the vehicle frame, and an attachment is connected to the boom arm for rotation with respect to the boom arm. The control system includes a controller that is configured to calculate a pre-determined acceleration limit of the attachment, and a sensor that senses acceleration of the attachment and communicate the sensed acceleration to the controller. The controller is configured to compare the pre-determined acceleration limit of the attachment to the sensed acceleration of the attachment and is configured to adjust a control valve to limit flow to the actuator in response to the sensed acceleration of the attachment being above the pre-determined acceleration upper limit.
