A movement device is moved along an X axis and a Y axis by providing a sensor configured to measure angle of rotation of at least one of a first and a second kinematic link about a respective axis of rotation. A force is imparted on the first and second kinematic links such that an angular displacement of the first and second kinematic links about the respective axis of rotation is achieved. The angular displacement of the first and second kinematic links about the respective axis of rotation is determined. The movement device is moved along the X axis and/or the Y axis in response to the determination of the angle of rotation of the first and second kinematic links about the respective axis of rotation until first and second kinematic links are vertical.

A portable crane formed of composite members. A composite mast is coupled to a composite boom. A boom end housing removably couples at a top of the mast and includes an enclosure. A first end of the boom couples within the boom end housing. A boom pivot couples to the boom end housing and couples the boom to the mast. An angle adjuster releasably secures the boom at a desired angle relative to the mast. In implementations an end cap is included at a second end of the boom, coupled to a sheave with a pin, the end cap covering a terminal end of a second end of the boom and extending along both sides of a slot in an upper surface of the second end and along a portion of a first side of the second end and along a portion of a second side of the second end.

The present invention relates to a system for lifting and manipulating a load. The system includes a gantry crane having a support rail, a support gantry, and a gantry beam connected to and traversing a space between the support rail and the support gantry. The gantry crane also includes a trolley disposed with the gantry beam. The system further includes a lifting platform secured to a top surface of the gantry beam, and a lifting device disposed with the lifting platform.

The present invention relates to a modular assembly, a site factory, for at least partially enclosing a site during construction of a structure. The modular assembly comprising: a plurality of portal frames, each portal frame comprising two columns and a roof beam, each column and roof beam comprising a plurality of pre-assembled units; a jack-up frame for each column; at least two first rails, each of the first rails being mounted to at least one of the roof beams; at least one second rail slidably mounted to the at least two first rails; and a plurality of panels of a flexible material configured to provide a full enclosure of the site and mounted above the roof beam. The or each second rail is configured to slidably receive at least one lifting device. The pre-assembled units are configured to be connected on site, and lifted using said jack-up frames, to form the portal frames, and wherein each first rail, and the or each second rail are configured to be mounted on the portal frames on site.

A system and method for construction of a framed structure which permits on-site storage and relocation of construction materials using trolleys and cranes supported by the framed structure. The system provides a runway surface for removable attachment of trolleys, crane bridges, and platforms by offsetting the first longitudinal beam and a second longitudinal beam from a cross beam and where the first longitudinal beam, second longitudinal beam, and cross beam of the system provide components for the framed structure.

An overhead crane monitoring system is for monitoring an overhead crane (1). The overhead crane (1) includes a travelling body (2) that travels along rails (4), a traverse trolley (3) that travels in a direction perpendicular to a travelling direction of the travelling body (2) along the travelling body (2), and a hoisting device (5) mounted on the traverse trolley (3). The overhead crane monitoring system includes a panoramic camera (6) disposed at one end portion of the travelling body (2). The panoramic camera (6) records an image in an overlooking posture. The image recorded by the panoramic camera (6) is displayed on a wide display (21) installed in a remote operation room. This enables providing an operator with an image appropriate for remotely operating the overhead crane (1).

A system for servicing a nuclear reactor module comprises a crane operable to attach to the nuclear reactor module, wherein the crane includes provisions for routing signals from one or more sensors of the nuclear reactor module to one or more sensor receivers.

An overhead crane monitoring system is for monitoring an overhead crane. The overhead crane includes a travelling body that travels along rails, a traverse trolley that travels in a direction perpendicular to a travelling direction of the travelling body along the travelling body, and a hoisting device mounted on the traverse trolley. The overhead crane monitoring system includes an imaging device (Camera) and a control device. The imaging device is installed on the travelling body. The imaging device is configured to change a recording direction and configured to zoom. The control device controls the imaging device to track and record a hoisting tool raised and lowered by the hoisting device based on an image recorded by the imaging device. This enables providing an operator with an image appropriate for identifying states of the hoisting tool or hoisted load of the overhead crane.
