Abstract: A hydraulic steering actuator system for a forklift with front and rear sections includes a hydraulic steering motor. The forklift front section includes a mast mounting a pair of fork blades and a pair of wheels. The forklift rear section mounts a pair of drive wheels. The forklift front and rear sections are connected by an articulated connection with a vertical rotational axis. The steering actuator motor driveshaft extends generally along the vertical rotational axis. First and second actuator mounting brackets are connected to the forklift front and rear sections respectively. One of the mounting brackets includes upper and lower locking assemblies locking the hydraulic steering motor driveshaft whereby torque applied to the steering motor is transmitted to the articulated connection for turning the forklift front section relative to the forklift rear section. The range of motion is preferably 180°-205° for accommodating side-loading operations from relatively high storage shelves, e.g. in narrow-aisle warehouses.

Abstract: A rubber tired self powered mine vehicle utilizing a low profile fork lift assembly for handling palletized materials underground. The fork lift assembly consists of a fork lift plate and a parallel spaced apart base plate. The base plate is attached to the front of a mining vehicle by bucket mounting hole. The position of the base plate relative to the mine vehicle may be adjustable. The upper part of the fork lift plate is attached to the upper part of the base plate by set of horizontally spaced apart pivot links. The lower part of the fork lift plate is attached to the lower part of the base plate by a set of spaced apart pitmans. The long arm of each pitman extends between the base plate and the fork lift plate, while the short arm extends upward from the connection to the base plate. The short arm of the pitmans are engaged by hydraulic cylinders for raising and lowering forks which extend from the fork lift plate. The hydraulic operating cylinders are disposed behind the spaced plate and the operating rods extend through appropriate openings formed in the base plate. The body of the mine vehicle is suspended from its axles by hydraulic axle suspensions. By raising the front of the mine vehicle frame and lowering the rear or vice versa additional movement of the forks is possible. Mounted in the center end, between the base plate and the fork lift plate, are a pair of links having horizontally offset connection points to prevent side way movement of these plates.

Abstract: A forklift-type automated guided vehicle includes a body and a control circuit unit received in the body, both a first fork arm and a second fork arm parallel to each other and formed on a front end of the body to forklift cargo, each of the first fork arm, the second fork arm and a bottom end of the body including at least one two-wheel differential driving assembly rotatably connected to the first and second fork arms, and the body, respectively, and electrically connected to the control circuit unit. The two-wheel differential driving assembly includes a left driving wheel and a right driving wheel formed opposite to each other which can be independently driven to realize differential rotation. The present disclosure not only can forklift cargo with a small turning radius, but also can realize left-to-right sideways movements and an in-place rotation and a U-turn movement.

Abstract: A self-moving operating machine with an integrated lateral movement and leveling device, including a chassis having a front part and a rear part, to which a fore axle and a rear axle, both provided with wheels, are constrained, respectively, and including an operating arm having one of its ends constrained to the rear part. The front part and the rear part are articulated to each other by a spherical coupling including two linear actuators, consisting of hydraulic cylinders aimed at operating in mostly vertical directions. A third actuator is rod-wise connected to the front and rear parts, and is aimed at operating according to mostly horizontal directions. The actuators are operated independently. There are provided means designed to measure loads weighing on at least one of the two wheels and to control locking of the rear axle to the rear part upon reaching predetermined limits.
