The improved hydraulic system utilizes a secondary hydraulic force control circuit that changes the gripping force on the load independently of movement of the clamp arms.

A method for operating a conveying system is provided. An overhead hoist transport (OHT) vehicle is provided, wherein the OHT vehicle includes a gripping member configured to grip and hold a carrier, and a receiver configured to receive a signal. The signal is transmitted to the receiver of the OHT vehicle. The OHT vehicle is moved toward the carrier, and the carrier is gripped by the gripping member of the OHT vehicle. A lifting force is determined based on a weight of a carrier, a number of workpieces in the carrier, or a vertical distance between the OHT vehicle and the carrier, and the lifting force is applied to the carrier.

A transfer device includes: a mounting unit (132) on which a target article (90) is to be mounted; and a transfer unit (T) that transfers the target article (90) between a storage unit (A) and the mounting unit (132), the transfer unit (T) includes a first transfer device (10T) that holds the target article (90) and moves the target article (90) in a depth direction (L), and a second transfer device (20T) that moves a portion of the target article (90) in the depth direction (L), the portion being mounted on the mounting unit (132), a first transfer distance (dl) by which the target article (90) is to be moved by the first transfer device (10T) is shorter than a total transfer distance by which the target article (90) is to be moved in the depth direction (L) between the mounting unit (132) and the storage unit (A).

A remote controlled luggage handler apparatus for loading and unloading luggage from tour buses includes a carrier body having a pair of drive tracks. A multi-axis arm has a base pivot unit coupled to a body top side, a proximal segment coupled to the base pivot unit, a distal segment, and a head pivot unit. A jaw comprises a jaw support coupled to the head pivot unit, a fixed mandible coupled to the jaw support, and a sliding mandible slidably coupled to the jaw support to secure a suitcase between the fixed mandible and the sliding mandible. A CPU, a first transceiver, and a battery are coupled within the carrier body. A remote control is in operational communication with the first transceiver to control the drive tracks and the arm. A charging port is configured to be installed within a storage bay of a tour bus to charge the battery.

A hydraulic control circuit operable to selectively hydraulically link first and second hydraulic actuators and to bypass that hydraulic link.

A hydraulic control circuit operable to selectively hydraulically link first and second hydraulic actuators and to bypass that hydraulic link.

A clamp assembly for a lift truck load handler that has a clamp leading edge that is raked back from bottom to top. The clamp leading edge is a blade edge, angled inward from the leading edge. The clamp assembly typically has a clamp plate with a front edge that forms at least part of the clamp leading edge. The clamp assembly typically has a toe plate that is harder and more wear-resistant than the clamp plate that wraps around a front edge of a lower portion of the clamp plate. The toe plate has a front edge that aligns with a front edge of the upper portion the clamp plate that together form the clamp leading edge.

A clamping equipment for lifting a load arranged to be coupled to a forklift truck includes a fixed frame which extends in a longitudinal direction and apt to be coupled to a carrier plate of a forklift truck; two jaws opposite each other and slidingly connected to the fixed frame along the longitudinal direction in order to be tightened in grip on a load; where each jaw includes a support connected to the fixed frame and configured to be moved in an integral manner with the fixed frame in a vertical direction and in a sliding manner relative to the fixed frame in the longitudinal direction; a panel coupled to the support and which has a surface configured to come into contact with a load to be handled; and a coupling assembly associated with the support and the panel and configured to movably couple the panel to the support with a motion component in a direction orthogonal to the panel and a motion component in vertical direction.

The present disclosure provides a goods taking mechanism and a carrying device. The goods taking mechanism includes a fixed member, a first clamping plate, a second clamping plate, and a driving assembly, where the first clamping plate and the second clamping plate are oppositely mounted on the fixed member and are connected to the driving assembly, and the first clamping plate and the second clamping plate are movable relative to the fixed member under the action of the driving assembly, to act on two opposing sides of a to-be-moved object. The goods taking mechanism of the present disclosure can clamp to-be-moved objects of different sizes, which helps reduce the distance between the adjacent to-be-moved objects.

A smart clamp load handler system configured for controlling a clamp and preventing over-clamping. The system having a first actuator coupled to a first clamp arm and a second actuator coupled to a second clamp arm, an actuator control valve configured to control flow of hydraulic fluid to the actuators, and an electrical controller configured for signaling the actuator control valve when compressing a load. In one embodiment, the electrical controller is configured for determining when to stop the closing of the clamp arms based on a series of first and second actuator position measurements, and a series of base-side and rod-side pressure measurements, then signaling the actuator control valve to stop the closing of the clamp arms.
