A tracked vehicle includes a pilot control module which enables the pilot to steer the tracked vehicle using an existing joystick of the tracked vehicle. The tracked vehicle also includes a dual track drive pedal which drives the tracks of the vehicle simultaneously. The joystick is used to make steering corrections when utilizing the dual track drive pedal.

A manipulator for concrete pumps having an articulated boom with at least two boom arms and a hydraulic drive that pivots one or more of the boom arms. A hydraulic cylinder has piston and rod side working volumes. A hydraulic circuit has a first switching state in which the hydraulic circuit connects a first working port for feed or discharge of hydraulic fluid to the rod-side working volume and connects a second working port for feed or discharge of hydraulic fluid to the piston-side working volume. In a second switching state, the hydraulic circuit separates the first working port from the first fluid channel and thereby connects the first fluid channel to the second fluid channel for the feed of hydraulic fluid from the rod-side to the piston side working volume. A sensor acquires an operating state variable based upon which an activation assembly sets the switching state.

A hydraulic valve assembly includes a connection section, a first valve section, at least one second valve section, and a hydraulic pilot control device with a pilot valve device. The first valve section has a first spool piston and a first spool diverter. The second valve section has a second spool piston and a second spool diverter. The first spool diverter and the second spool diverter are each switchable to at least a first spool diverter switching position and a second spool diverter switching position. Pilot pressure is applied in parallel to the first spool diverter and the second spool diverter via the hydraulic pilot control device in a first switching position of the pilot valve device for switching together into the first spool diverter switching position.

Embodiments of this document provides improved safety logic for a mobile container handler of the reach stacker or top pick type. The improved logic involves limitations surrounding the hoist function of the machine subsequent to attaching to a shipping container. This improvement addresses damage to the container spreader caused by abrupt joystick hoist inputs by the operator immediately subsequent to attaching onto a shipping container. Due to space between the spreader arms and spreader body, which is so designed to facilitate movement of the arms inside the spreader body, sudden vertical movement of the spreader results in impact forces being exerted on various parts of the spreader body and spreader arms. These impacts accelerate fatigue leading to premature catastrophic failure of the spreader body and/or spreader arms' structural steel.

A guide display unit for a crane, wherein a data processing unit: calculates a measurement area corresponding to the measurement area of a camera; the measurement area from the viewpoint of the camera and generates a first image; performs mosaic-processing on the image captured by the camera according to the particle size of the three-dimensional map and generates a second image; performs registration processing on the first image and the second image and calculates the amount of deviation between the first image and the second image; corrects the position of a guide frame figure with respect to the image of a suspended load and a feature on the basis of the calculated amount of deviation; and overlays the guide frame figure on the images of the suspended load and the feature and displays the result on the data display unit.

A hydraulic valve assembly includes a first spool valve and a first selector valve for actuating a first hydraulic consumer port or a second hydraulic consumer port, and a second spool valve and a second selector valve for actuating a third hydraulic consumer port or a fourth hydraulic consumer port. A shut-off valve is arranged in a common pressure channel. A branch channel with first and second pressure branch channels branches off the pressure channel upstream of the shut-off valve. The first selector valve connects the first pressure branch channel to a first connection line in a first switching position and connects the second pressure branch channel to a second connection line in a second switching position. The second selector valve, in a first switching position, connects the first connection line to the control channel and, in a second switching position, connects the second connection line to the control channel.

The invention relates to an arrangement of a control system arranged, or to be arranged, on a hydraulic lifting device, and of a mobile control module, via which the control system can be remote-controlled. The control system can be supplied with sensor data via signal inputs, and a processing unit of the control system is configured to calculate from said sensor data and from stored lifting device-specific data information, which is characteristic for the current lifting load situation and/or the allowability of work processes on the lifting device, optionally in the given current lifting load situation. The control system has a mode, in which the control system transmits the information that is characteristic for the current lifting load situation and/or the allowability of work processes on the lifting device, optionally in the given current lifting load situation, to the mobile control module, via a transmitting and receiving module, to a transmitting and receiving module of the mobile control module in a wireless and/or cable-bound manner. From said information, a processing unit of the mobile control module calculates graphic data for a display, which can be displayed for a user via a display unit.
