An exemplary embodiment of the present disclosure relates to an automatic stopping device for a forklift, and more particularly, to an automatic stopping device for a forklift, which forcibly stops the forklift by simultaneously operating a forward clutch and a reverse clutch when an operator moves away from the forklift in a state in which an engine is turned on. According to the automatic stopping device for a forklift according to the exemplary embodiment of the present disclosure, first, it is possible to prevent a safety accident by forcibly stopping the forklift in the absence of the operator, and second, the automatic stopping device for a forklift is economical because it is possible to effectively stop the forklift using an additional simple configuration.

A pallet truck has a brake release mechanism. The pallet truck has a break release mechanism operably coupled to a brake for stopping rotation of a drive wheel. The brake release mechanism includes a brake release sensor and a profile feature that is detectable by the brake release sensor. The profile feature is fixedly coupled to a pivot shaft of a tiller arm of a tiller, and configured to rotate with the pivot shaft as the tiller arm is pivoted. The brake release sensor is positioned adjacent to the pivot shaft and configured to output a signal that causes the brake to release when the profile feature is detected.

A materials handling vehicle includes at least one contactless obstacle sensor that scans at least two speed zones, each speed zone being defined in an area at least partially in front of a forward traveling direction of the vehicle and being associated with a unique predetermined maximum speed greater than zero (0) miles per hour. A controller that receives information obtained from the at least one obstacle sensor and, if the vehicle is traveling under remote control, the controller is configured to limit the vehicle speed to the predetermined maximum speed of a corresponding one of the at least two speed zones based upon the detection of an obstacle in that speed zone.

A system for controlling an industrial truck with a drive portion including a traction drive portion, a steering portion, and a load portion, comprises a portable transmitting unit configured to be positioned away from the industrial truck. The system further comprises at least three transmitting and receiving units positioned in a predetermined spatial arrangement with respect to one another on the drive portion. An evaluation unit is provided that is configured to determine a position of the portable transmitting and receiving unit relative to the industrial truck by measuring signal propagation times. The industrial truck further comprises a control unit configured to send a control command for traction drive and/or steering if the relative position of the portable transmitting and receiving unit is located within a predetermined spatial region relative to the industrial truck.

Systems and methods for a floor conveyor include a sensor device and a control unit, wherein the control unit is operable to control the travel functions of the floor conveyor, wherein the sensor device is arranged to be able to provide the control unit with sensor data, wherein the sensor device is arranged such that it can detect objects in a plane. The plane is arranged to a have a follow section and a steer away section. And the floor conveyor is arranged such that it can determine an object to follow.

A forklift active braking control method based on power shift transmission, comprising the following steps: step 1: obtaining forklift state parameters, if the current state of the forklift is an active braking state, performing step 2; step 2: inputting a current speed signal of the forklift, and obtaining duty ratio parameters that are impact-free and can produce a maximum braking force at the current speed, and outputting proportional solenoid valve control parameters of the transmission according to the obtained duty ratio parameters; step 3: using the proportional solenoid valve control parameters to control the proportional solenoid valve of the transmission to take action, and controlling the forklift power system to output a driving force opposite to a current movement direction of the forklift to drive the forklift to actively brake; step 4: exiting the active braking of the forklift when the forklift speed is detected to be zero.

A system is described for presenting information relating to lifting and moving a load object with a vehicle. Upon the lifting, a dimensioner determines a size and a shape of the load object, computes a corresponding spatial representation, and generates a corresponding video signal. During the moving, an imager observes a scene in front of the vehicle, relative to its forward motion direction, and generates a video signal corresponding to the observed scene. The imager has at least one element moveable vertically, relative to the lifting. A display renders a real time visual representation of the scene observed in front of the vehicle based on the corresponding video signal and superimposes a representation of the computed spatial representation of the load object.

An industrial vehicle includes a hydraulic brake device, a hydraulic load handling device, a first hydraulic circuit, a second hydraulic circuit, a pressure compensating circuit, and a controller. The controller sets an electromagnetic valve to a first position during operation of the load handling device. The controller sets the electromagnetic valve to a second position and controls an electric motor to drive a hydraulic pump when determining that pressure needs to be accumulated in a hydraulic accumulator based on a detection result of a detector. When the electromagnetic valve is at the second position, hydraulic pressure generated by driving the hydraulic pump is applied to a pressure compensating valve and produces a force acting in a direction to disconnect the hydraulic pump and an oil tank from each other, so that hydraulic pressure is generated in a first oil passage to be accumulated in the hydraulic accumulator.

A materials handling vehicle includes at least one contactless obstacle sensor that scans at least two speed zones, each speed zone being defined in an area at least partially in front of a forward traveling direction of the vehicle and being associated with a unique predetermined maximum speed greater than zero (0) miles per hour. A controller that receives information obtained from the at least one obstacle sensor and, if the vehicle is traveling under remote control, the controller is configured to limit the vehicle speed to the predetermined maximum speed of a corresponding one of the at least two speed zones based upon the detection of an obstacle in that speed zone.

A supplemental control system for a materials handling vehicle comprises one or more sensors capable of defining multiple contactless detection zones at least towards the front of the forward travel direction of a remotely controlled vehicle. The vehicle responds to the detection of objects within the designated zones based upon predetermined actions, such as to slow down or stop the vehicle, and/or to take other action, such as to perform a steer angle correction.
