In an embodiment of the disclosure, lift apparatus may include a frame including an attachment device configured to attach to a tilting plane of a loader having a forward facing loader arm, a pair of wheels connected to the frame, a first wheel of the pair of wheels located on a first side of the frame and a second wheel of the pair of wheels located on a second side of the frame. The lift attachment apparatus may further include a boom or forks connected directly or indirectly to the frame, wherein control of the boom or forks is provided by application of force to the attachment device by the forward facing loader arm in a downward direction to create lift and rotation of the tilting plane causing rotation of an end of the boom or forks about the first wheel and the second wheel. The first wheel and second wheel being mechanically aligned to act as a stable fulcrum.

The present application provides a movement buffering control system and method for forklift tilt cylinder based on angle compensation in the field of forklift control, which includes a tilt cylinder configured to control forward and backward tilting of a mast of a forklift and a lift cylinder configured to control the lifting of a fork, and further includes a controller, wherein a signal input terminal of the controller is connected to a first angle sensor to measure a tilt angle of the mast relative to a vertical plane, a second angle sensor to measure a tilt angle of a vehicle body relative to a level ground, and a pressure sensor, and wherein a signal output terminal of the controller is connected to a display, a forward-tilting proportional valve to control the oil for forward-tilting of the tilt cylinder.

A vehicle-mounted device includes an analysis unit and a control unit. The analysis unit detects an insertion target into which an insertion blade can be inserted, on the basis of sensing information acquired from a spatial recognition device. The control unit performs a loading misalignment determination to determine whether or not the insertion target loaded on a conveyance destination is misaligned from the conveyance destination on the basis of the sensing information.

A fork lift apparatus is mounted on a truck for picking up a load, placing the load in a traveling position on the truck, and for unloading the load. The apparatus comprises a lift frame, a shaft, a pair of spaced arms secured to the shaft, a cross member spanning between the distal ends of the arms distal and carrying the forks. The cross member is rotatable relative to the support arms. A pair of drive hydraulic cylinders rotates the shaft and thus moves the arms and the load between a loading/unloading position in which the load may be placed on the forks and the traveling position so that the load may be transported by the truck. A self-leveling system is provided for maintaining the load in a substantially level position as it moves between its loading/unloading and traveling positions.

A center of gravity estimation device includes a tilt cylinder pressure sensor detecting a pressure on a rod side of the tilt cylinder, a tilt cylinder pressure sensor detecting a pressure on a bottom side of the tilt cylinder, a lift cylinder pressure sensor detecting a pressure of a lift cylinder, and an electronic control unit performing estimation calculation of a center of gravity of a cargo W loaded on a fork using the pressure on the rod side of the tilt cylinder, the pressure on the bottom side of the tilt cylinder, the pressure of the lift cylinder, and data on a structure of a cargo handling device.

An infrared light-transmitting system for determining the position (e.g., angle and extension) of a boom is provided. The system includes a vehicle with wheels or a track that move the cab. A chassis or frame supports the cab and boom. In various embodiments, the boom extends and rotates; for example, the boom can rotate in 1 or 2 dimensions. The boom interconnects the chassis at the first end to the attachment at the second end. At least one pivot couples the boom to the chassis to rotate the boom about the pivot relative to the chassis. A transmitter emits infrared light signals that are reflected off a reflector to a detector to determine the real-time position of the attachment and/or boom.
