It is reported in the present invention a device (A) to monitor the tension on an anchoring line (LA) of a floating platform for oil exploration or production at sea, which is mounted at a point on the anchoring line without it becoming an integral part thereof, which basically comprises: an upper bar (1) and a lower bar (2), which are interconnected at one end by a hydraulic cylinder (CH1) and on the other end by a solid vertical bar (4).

A ligature attachment device for use with a ligature is disclosed, the ligature attachment device comprising a proximal section comprising a loop retainer section, a distal section comprising a tool section, a central section comprising a central ligature spool section having a centrally located cinch aperture and the central ligature spool section is coupled to the loop retainer section and the tool section. The loop retainer section having a loop retainer profile configured to retain a loop of the ligature frictionally engaged with the central ligature spool section. The cinch aperture having an aperture shape configured to allow at least two sections of a ligature to be removably retained in the cinch aperture whereby the cinch aperture can removably retain the loop of the ligature. The tool section comprises a first tool for removably joining a second tool.

A line-guiding device includes links connected to one another in an articulated manner and which form a loop consisting of an upper strand, a deflection region, and a lower strand. Adjacent links can pivot relative to one another about a pivot axis. The pivot axes are located closer to a loop inner side than to a loop outer side at least in some of the links. Each link has two side flaps opposite one another. Side flaps of adjacent links form at least one running surface on the loop inner side. At least some of the links have a roller projecting from the running surface. The upper strand and the lower strand can abut over the running surface such that the upper strand and the lower strand can move by means of the rollers. The running surface in at least some of the links is interrupted by recesses.

The present disclosure is directed to hook and chain assemblies, including those suitable for use in food processing environments. The chain passes through a hook body, where it is secured by a retaining pin when under tension or load. The chain can be quickly and easily removed for servicing, cleaning, and sanitation of the hook body.

A chain catch that is capable of being attached to various bases so as to allow the quick and simple affixation of the chain catch to any vertical chain. The chain catch has an upper body and a lower body. The upper body is designed to trap a vertical chain within its internal design while it remains within its vertical orientation, and the lower body is designed to attach to a load and to the upper body. When the tension is taken off of the chain within the chain catch and the upper body is tilted, the chain may be vertically raised, free from the chain catch or the chain catch and its attached barbell can be vertically raised.

A push pull chain is provided with chain links that are connected to each other by respectively one chain joint, designed in a space-efficient manner. The chain joints of a first chain section with their joint axes have a first orientation, whereby the joint axes of the chain joints of a second chain section are arranged in a second orientation that is twisted around the longitudinal axis of the push pull chain or whereby they can be set to this orientation. In addition, a pertaining chain drive is provided.

A link unit includes two first chain plates and an assembling pin. Each of the first chain plates has a first inner end section, a first outer end section misaligned from the first inner end section, and opposite inner and outer side surfaces. The first outer end section of each of the first chain plates is formed with a connecting hole that has a first hole portion, a second hole portion, and a neck portion located between the first and second hole portions. The assembling pin is inserted through the connecting hole of each of the first chain plates, and is prevented from moving past the neck portions of the first chain plates so as to be positioned in the second hole portions of the first chain plates.
