The problem of potentially damaging a pallet layer that is gripped by clamps of a depalletizing tool is solved i) by detecting the real position of the layer using a pad on the tool that is movable with the clamps towards the pallet layer and whose detected stopping position determines the real position of the layer, and ii) while the layer is gripped by the clamp, by inserting under the layer curtains; the pressure on the layer by the clamps being adapted to the ease to go underneath the layer.

The present invention provides an automatic container landing device based on an expert system and a control method therefor. The device comprises at least four groups of cameras and at least six groups of single-point laser devices, wherein the at least four groups of cameras and four groups of single-point laser devices in the at least six groups of single-point laser devices are arranged at four spreader corners of a spreader fixing support; two groups of single-point laser devices in the at least six groups of single-point laser devices are respectively arranged on the outer sides of two short edges of the spreader fixing support; the front end of the spreader fixing support is lower than the rear end of the spreader fixing support; and the first group of cameras and the second group of cameras in the at least four groups of cameras, as well as the first group of laser devices and the second group of laser devices, and the third group of cameras and the fourth group of cameras, as well as the third group of laser devices and the fourth group of laser devices, are arranged at the front end and the rear end of the spreader fixing support respectively. According to the automatic container landing device based on the expert system, manual container landing experience is integrated into various sensors, a spreader is controlled by means of sensing signals, low-point and high-point container landing of a container is conducted, automatic dynamic container landing of the container is achieved, high-precision measurement is achieved with the cooperation of the cameras and the single-point laser devices, and therefore, the precision and efficiency of the container landing operation are improved.

A method for installing building panels, the method including forming a composite building panel from a plurality of panels, transporting the composite building panel to the site of installation and lifting the composite building panel by a lifting facility into position within a building.

A connecting component with built-in radio frequency identification element which includes a main body and a radio frequency identification element is provided. The main body has a cylindrical body part and a head, wherein the body part has a connecting end and a free end; the head is connected to the connecting end, and the maximum outer diameter thereof is greater than an outer diameter of the body part; the head has an accommodating hole, and an opening of the accommodating hole is formed at a top of the head; the radio frequency identification element can be inserted into the accommodating hole. When the connecting component is used to fixedly connect the rigid object, the radio frequency electronic component provides a space to store database; with the radio frequency identification reader, industry can read the data at any time during the inspection or the maintenance stages, which improves the convenience of obtaining data and the efficiency of operation.

A spreader (24) comprises a main frame carrying container connector arrangements configured to engage with a transport container (10); a rotator enabling rotation of the main frame in relation to a crane bracket about a substantially vertical rotation axis (A2); a rotation motor configured to, responsive to a rotation control signal, operate the rotator to rotate the main frame; a rotation detector configured to detect rotation of the main frame in relation to the crane bracket; and a control system configured to, based on a discrepancy between the rotation control signal and a rotation detected by the rotation detector, generate a rotation alert signal.

Described is a method for taking up an elongate object from a ground surface using a hoisting yoke coupled to a lifting means. A beam-like support frame of the hoisting yoke extends in a longitudinal direction of the object and slings provided at end parts of the support frame take up the object. The object is taken up in a sling by holding a first outer end of a sling with a first holding means provided at an end part of the support frame and letting it hang down from the first holding means to a position in the vicinity of the object; paying out a messenger line from the end part using a messenger line winch, feeding it under the object and coupling it to a second outer end of the sling hanging from the first holding means; taking in the messenger line so that the sling is carried under the object and to the relevant end part; and coupling the second outer end of the sling to a second holding means provided at the end part, thus forming one of the slings for the object.
