A device and a method for decelerating a vehicle having a front-loading device has a brake system and sensors for measuring the mass and the center of gravity of a load. An electronic evaluation and control unit evaluates the sensor data to determine a maximum brake deceleration in forward travel, in order to prevent the vehicle tilting about the front axle. At least one sensor of the brake system generates a sensor signal in an emergency braking situation for triggering an emergency braking operation, in which the delimitation or reduction of the effective brake pressure in the wheel brake cylinders of the front axle is canceled and, with the exception of an ABS control operation, the full brake pressure is introduced in a controlled manner by way of a primary brake valve into the wheel brake cylinders of the front axle.

A single drive axle brake includes: a differential unit (300) for separating and transferring the driving power received from the motor (100) to both sides; a differential gear unit (340) for distributing and transferring the driving power transferred from the motor to the wheels disposed on both sides; and a brake unit (360) for restricting the differential gear unit (340). Differential side gears (344, 345) geared with a differential pinion gear are disposed inside a differential gear case (347) coupled with a crown wheel (341) of the differential unit, and the brake unit (360) includes a main brake (380) for restricting and stopping the differential gear case (347), and a subsidiary brake (390) for stopping the rotation of the power shaft (349).

A mobile lift apparatus includes a mobile base frame with sets of height adjustable, triple caster units, frame mounted floor brakes, a load deck, scissor linkage engaged between the base frame and the load deck, and a load table movable on the load deck. An actuator is engaged with the scissor linkage to extend and retract the scissor linkage.

A wheel kit for use with a boat lift includes an upper member attachable to the boat lift, and a lower member slidably disposable within the upper member. The lower member contains an axle and a wheel assembly. A braking member includes a base plate with a first side and an opposing second side, a wedge portion outwardly extending from an upper end of the first side, and a tab outwardly extending from a lower end of the first side of the base plate. The braking member slidably disposes upon the axle via an aperture contained within the base plate. When positioning the lower member into the upper member to retract the wheel assembly, the wedge portion of the braking member contacts a closed terminal end of a slot contain within the upper member, outwardly urging the braking member against the wheel assembly to prevent rotation of the wheel assembly.

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 device and a method of controlling the lift device are provided. The lift device has a lifting mechanism supporting a lifting platform relative to the chassis. An electric motor is drivingly coupled to a traction device, and a traction battery is in electrical communication with the electric motor. A user input is provided to control a speed of the lift device by inputting a requested speed. A controller is configured to, in response to the lift device being on a non-zero grade and if the requested speed is greater than a predetermined speed, command the electric motor to output a braking torque and provide electrical power to the traction battery, and limit the speed of the lift device to the predetermined speed.

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.

An assist control device controls an electric motor assisting traveling of a mobile object. The assist control device includes an operating switch and a control part. The operating switch is configured to be turned on when operated by a user. The operating switch is configured to be turned off when released from being operated by the user. The control part controls the electric motor to output an assist force when the operating switch is turned on.

Provided is a work vehicle capable of satisfying a user's demand to brake performance in a flexible manner. A wheel loader 1 comprises a controller 5 storing a plurality of control characteristics each of which is set such that a brake valve control pressure Pi of a solenoid proportional valve 45 increases as a pedal angle θ of a brake pedal 43 increases, and under the condition where a pedal angle θ is equal to or less than a predetermined pedal angle θ, an increase rate of the brake valve control pressure Pi with respect to the pedal angle θ varies. In a case where the pedal angle θ detected by a potentiometer 33 is equal to or less than the predetermined pedal angle θth, the controller 5, calculates the brake valve control pressure Pi based on the selected one control characteristic.

An axle of an industrial vehicle, in which a parking brake can be maintained easily. The parking brake is arranged adjacent to a power transmission device outside an axle housing. The parking brake includes a brake housing, a brake shaft supported rotatably around the axis of the brake housing, a brake gear attached to the brake shaft and meshed with a transmission gear, first brake plates attached to the brake shaft, second brake plates attached to the brake housing and alternately arranged with the first brake plates, and a brake piston arranged so as to move toward and away from the plates and in the brake housing for bringing the plates into pressure contact with each other.
