The first pivoting arm section and the implement manipulating section together being laterally foldable, with respect to the base telescoping section, about a lateral folding pivot axis which extends normal to the combined boom/arm pivot axis to facilitate transport of the boom vehicle with respect to the base telescoping section to facilitate transport of the boom vehicle along a roadway.

A lift device includes a chassis having a first end and an opposing second end, a first actuator coupled to the first end of the chassis, a second actuator coupled to the first end of the chassis, a third actuator coupled to the opposing second end of the chassis, a fourth actuator coupled to the opposing second end of the chassis, and a control system. The control system is configured to fluidly couple at least two of the first actuator, the second actuator, the third actuator, and the fourth actuator, and fluidly decouple and actively control the at least two of the first actuator, the second actuator, the third actuator, and the fourth actuator.

An assembly of a controller is to be arranged on a hydraulic lifting device, and a mobile control module can remotely operate the controller. Sensor data can be fed to the controller via signal inputs, and a processor of the controller is configured to calculate first information characteristic of a current position of the hydraulic lifting device from the sensor data and from specific data of the hydraulic lifting device stored in a memory. The controller has an operating mode in which parameters for a further position of the hydraulic lifting device and/or for a lifting load can be input at the mobile control module. Second information characteristic of the further position and/or the lifting load is calculated from the parameters, and the stored data is compared with the first information and/or the specific data.

This crane is provided with: a operable functional unit; an actuator; a generation unit that generates a first control signal including a first deceleration signal section composed of a control signal for decelerating a speed of the operable functional unit from a first speed to a second speed and a first constant-speed signal section composed of a control signal for maintaining the speed of the operable functional unit at the second speed; a filter unit for filtering the first control signal to generate a second control signal; and a control unit that controls the actuator so as to decelerate the operable functional unit based on the second control signal, then controls the actuator so as to maintain the speed at the second speed, and controls the actuator so as to zero the speed when a load has been moved to a location satisfying a prescribed condition.

The present invention relates to a tower crane, in particular a revolving tower crane, comprising a crane tower composed of a plurality of tower pieces, a main boom arranged at the tower tip, and a counter-boom, wherein at least one main hoist rope is guided over the main boom to take up the load and at least one counter-boom hoist rope is guided over the counter-boom to take up a balance weight.

This invention relates generally to a method for making a deck for use in construction. In one embodiment, the method includes, but is not limited to, positioning a first box tube substantially parallel to a second box tube; attaching a plate to the first box tube and the second box tube, the plate extending between the first box tube and the second box tube; coupling a hydraulic cylinder to the plate; slidably inserting a first extension member at least partially into the first box tube; slidably inserting a second extension member at least partially into the second box tube, the first and second extension members having a beam extending therebetween; coupling the hydraulic cylinder to the beam; positioning a platform having one or more wheels on the plate and over the hydraulic cylinder such that the platform is rollable relative to the plate; attaching the platform to the beam such that the platform is operable to retractably extend beyond an edge of a floor of a building in conjunction with the first and second extension members in response to actuation of the at least one hydraulic cylinder; and forming a rectangular cuboid basket comprised of six faces with a connecting mechanism on a top face.

A robotic system having a movable gantry robot (10) for conducting construction operations. The gantry may have an expandable bridge (20) and articulated gantry support legs (34) as well as a support track system (60) holding a gantry robot (800) which may hold one or more implements and peripheral devices (806). The device can be moved by propulsion mechanisms, a controller, and one or more geo-positioned control devices to provide position information for the robotic gantry as it moves back and forth along a plurality of work sites (700). The robotic gantry is connected to a power supply system (236). The controller is automated, self-navigating, and activates, deactivates, and/or changes the operation of the propulsion mechanisms, and deploys, retracts, activates, deactivates, and/or changes the operation of one or more of the construction implements. The height of the frame may be adjusted by extending and rotating risers and booms to accommodate different building heights or sub-level heights at a worksite. A conveyor system is optimized for removing dirt from or delivering material to the robotic arm. This invention can be applied to automating construction jobs including surveying, land preparation, excavation, foundation, masonry, framing, and additive fabrication.
