An industrial vehicle includes a travel direction detector configured to detect a travel direction of the industrial vehicle, a vehicle speed sensor configured to detect a vehicle speed of the industrial vehicle, a travel direction determiner, an object detector, and a controller. The controller is set in a particular state when the vehicle speed of the industrial vehicle is equal to or higher than a first vehicle speed threshold value. In the particular state, even when a travel direction command is changed by the travel direction determiner, the controller recognizes that a traveling state of the industrial vehicle before the travel direction command is changed continues and the object detector operates based on the traveling state of the industrial vehicle before the travel direction command is changed.

An industrial vehicle includes a controller. The controller sets a first upper deceleration limit as a set upper deceleration limit, if a first condition is satisfied, to perform first deceleration limiting. The first condition is satisfied when at least one of a high lifting height of the industrial vehicle, a material weight equal to or greater than a threshold, and an empty driver seat is detected. The controller sets a second upper deceleration limit as the set upper deceleration limit, if a second condition is satisfied, to perform second deceleration limiting. The second condition is satisfied when a distance between the industrial vehicle and an obstacle is less than a threshold. The controller performs priority control if the first condition and the second condition are satisfied so that the first upper deceleration limit is set as the set upper deceleration limit in preference to the second upper deceleration limit.

A rolling lift includes a tiltable and laterally shiftable load table. Tilt mechanisms at the mutual corners of a lift deck and the load table enable tilting of the load table. The apparatus caster units at corners of the cart frame and a handle stowable relative to a base frame of the lift.

The present disclosure relates to a handling equipment, a handling equipment control method, and a controller. The handling equipment (100) includes a controller. The controller executes program instructions to implement the following steps: determining whether the handling equipment (100) carries a carrier (105); determining a vehicle speed of the handling equipment (100); setting a first protection region according to the vehicle speed and a first profile of the handling equipment (100) when the handling equipment (100) does not carry the carrier (105); and setting a second protection region according to the vehicle speed and a second profile of the handling equipment (100) when the handling equipment (100) carries the carrier (105).

The invention relates to a handling machine comprising a hydraulically actuable member (OF), a hydraulic actuating device (DA) configured to actuate the member (OF); a system of solenoid valves (EV1, EV2); a hydraulic connecting line (LR) between the solenoid valves; a pressure sensor (CP1) in the connecting line (LR); a feed line (LA) which connects the second solenoid valve (EV2) to the actuating device (DA), a pressure sensor (CP2) in the feed line (LA). The control system (130) is configured to detect a malfunction of at least one of the solenoid valves (EV1, EV2) depending on one or more pressures measured by the or one of the pressure sensors (CP1, CP2) and on the electrically powered state of one or more solenoid valves.

A delivery system includes a handheld electric lift configured to lift at least one vaporizer vessel, and a cabinet configured to hold the at least one vaporizer vessel. The lift includes an elongated mast, an effector attached to the mast, a handler configured to move the lift, and at least one caster. The effector is controlled by an electric power source to move along the mast. Each of the at least one caster includes a stopper and a wheel. The stopper is elongated and is disposed above the wheel. The stopper is configured to engage with the wheel to prevent the wheel from swiveling when the stopper is pushed down. The stopper is further configured to disengage with the wheel to allow the wheel to swivel when the stopper is released. The cabinet includes at least one channel configured to accommodate the at least one caster.

A lift truck (10) has a pair of wheel assemblies (21) each of which is rotatable about a pivot point (24) relative to the chassis (12) of the truck through at least 90 degrees between a forward mode and a sideward mode. The wheel (18,20) of each assembly is laterally offset from the assembly's pivot point (24), causing the wheel to describe an arcuate path over the ground as it transitions between the forward and sideward modes. During the transition, an actuator acts on each wheel assembly (21) to pivot the assembly about the pivot point (24), while drive is applied to the wheel to positively drive the wheel along the arcuate patch at a speed that matches the pivotal rotation caused by the actuator. This positive drive imparted to the wheels (18,20) during the transition prevents the truck from rolling if it is located on a slope during the change in orientation of the wheel assemblies (21).

A hydraulic brake system for an industrial vehicle includes a master cylinder having a brake pedal, a brake device, and a master cylinder fluid passage. The hydraulic brake system includes a hydraulic fluid tank, a control valve, an actuator, an actuator fluid passage, a fluid return passage, a first solenoid valve, a second solenoid, a third solenoid valve, and a controller. When braking is performed by the master cylinder, the controller controls the first solenoid valve to open the master cylinder fluid passage, and the second solenoid valve to close the actuator fluid passage. When braking is performed by the actuator, the controller controls the second solenoid valve to open the master cylinder fluid passage, and the second solenoid valve to close the actuator fluid passage, and when the hydraulic pressure of the brake device is released, the controller controls the third solenoid valve to open the fluid return passage.

A hydraulic brake system for an industrial vehicle includes a master cylinder having a brake pedal, a brake device, and a master cylinder fluid passage. the hydraulic brake system includes a control valve disposed in the master cylinder fluid passage, an actuator, an actuator fluid passage, a first solenoid valve provided in the control valve, a second solenoid valve provided in the control valve, a controller configured to control the first solenoid valve, and the second solenoid valve. When braking is performed during manual operation, the controller controls the first solenoid valve to open the master cylinder fluid passage, and the second solenoid valve to close the actuator fluid passage. When braking is performed during automated operation, the controller controls the second solenoid valve to open the actuator fluid passage, and the first solenoid valve to close the master cylinder fluid passage.
