A materials handling vehicle is provided comprising: a support structure including a first member; a movable assembly coupled to the support structure; a hydraulic system; and a control system. The support structure further comprises lift apparatus to effect movement of the movable assembly relative to the support structure first member. The lift apparatus includes at least one ram/cylinder assembly. The hydraulic system includes a motor, a pump coupled to the motor to supply a pressurized fluid to the at least one ram/cylinder assembly, and at least one electronically controlled valve associated with the ram/cylinder assembly. The control structure may estimate a speed of the movable assembly from a speed of the motor and may control the operation of the at least one valve using a comparison involving the estimated movable assembly speed and a determined speed, and the comparison may not involve use of an operator commanded speed.

The present invention relates to an order picker with a wiring mechanism, belonging to the technical field of manned elevation equipment. The order picker with a wiring mechanism comprises a stationary part, an elevation mechanism and an elevation part, wherein the wire suitable for transmitting signals is connected between the stationary part and the elevation part. It also comprises a wire accumulator which acts on the wire in such a way that the wire is always tensioned between the stationary part and the elevation part; when the elevation part is raised, the wire accumulator starts to pay out the wire, and when the elevation part is lowered, the wire accumulator starts to stow the wire. The present invention adopts a wire accumulator structure which can avoid the wires which come from the chassis being nipped during elevation of the elevation structure.

A system for moving a receptacle. The system includes: a coupling wall; an internal carriage provided substantially adjacent the coupling wall, the internal carriage being movable along the coupling wall along a predetermined path; an external carriage provided substantially adjacent the coupling wall and substantially in register with the internal carriage with the coupling wall extending between the internal and external carriages, the external carriage being movable along the coupling wall, the external carriage including a receptacle attachment for securing the receptacle thereto; and a carriage actuator operatively coupled to the internal carriage for moving the internal carriage along the predetermined path. The internal and external carriages are magnetically coupled to each other across the coupling wall so that when the internal carriage is moved along the predetermined path, the external carriage follows the internal carriage and remains substantially in register therewith.

A lifter device includes: a pole; a lifting member configured to be guided by the pole; a motor configured to generate power used for ascending and descending of the lifting member; a transmission mechanism configured to transmit the power of the motor to the lifting member; and a preventing member configured to prevent the descending of the lifting member when the power is not transmitted.

A device for moving a fork carrier of a forklift includes an attachment unit arranged on a lifting mast with a scissor lever device having at least two oppositely rotatably mounted lever arm swings, which are rotatably contacted at at least one bearing point and which hold one fork carrier substantially normal to an axis of the lifting mast. The lever arm swings in a support region facing fork carrier and a support region facing the lifting vehicle have respectively at least one fixed support unit, and a support unit, which is displaceable when the scissor lever device is extended. At least one displaceable support unit, is slidable directly in contact with the lifting mast so that a direct force input into the lifting mast is established.

Embodiments relate to an autonomous robot including forks for loading a pallet onto its body. With the pallet loaded, the autonomous robot moves to a target location and then unloads the pallet automatically. To load the pallet, the forks are inserted below the top deckboard of the pallet, and then raised by lifting devices. The body of the autonomous robot is moved forward while retracting the forks to place the body under the pallet. Then the forks are lowered to mount the pallet onto the upper surface of the body. The autonomous robot navigates to the target location automatically, and then unloads the pallet by lifting the pallet from the upper surface of the body. Such loading or unloading of the pallet by the autonomous robot is performed autonomously without using additional equipment or manual involvement.

A material handling vehicle may include a clamp assembly, the clamp assembly including a housing, a grip assembly, and a power source. The grip assembly may be pivotally engaged with the housing. The power source may be in electrical communication with the grip assembly. The grip assembly includes a lobe pivotally engaged with the housing and a contact supported by the lobe, the contact being electrically conductive.

A materials handling vehicle is provided comprising a power unit, a mast assembly and a fluid supply system. The mast assembly is coupled to the power unit. The mast assembly comprises a weldment, a movable element and a ram/cylinder assembly coupled to the movable element to effect movement of the element. The fluid supply system includes manifold apparatus and at least one fluid line coupled to the manifold apparatus and the ram/cylinder assembly. The manifold apparatus provides pressurized hydraulic fluid to the ram/cylinder assembly via the fluid line to raise the movable element. The manifold apparatus is mounted to the mast assembly.

A lifting/skidding device includes an electric motor, a gear coupled to the motor and a lifting/skidding mechanism coupled to the gear, wherein the motor is embodied as a permanent magnet synchronous machine. The lifting/skidding device is adapted for lifting/skidding an offshore construction.

A forklift includes a vehicle body, a fork and a forward movement driving mechanism. The vehicle body includes a main body and two branch arms, the main body is provided with two ends opposite to each other, the two branch arms are respectively arranged at two ends of the main body and extend toward a rear of the vehicle body, the two branch arms are arranged opposite to each other and enclose with the main body to form an accommodating space, and a first mounting space is formed inside one of the branch arms. The fork is arranged in the accommodating space, the fork includes a first fork arm and a second fork arm, and the first fork arm is located above the second fork arm. The forward movement driving mechanism includes a first driving assembly and a second driving assembly.
