A braking device for the frictional braking of ropes or belts is described which includes direction changing or guiding structure made in the shape of a loop with at least 360.degree. bending to obtain braking friction, an inlet for the one rope part and an outlet for the other load-supporting rope part, and an attachment for a load-supporting device having a direction of force which is essentially opposite the direction of force in the load supporting rope part, whereby the ingoing rope part ca...

A device and method for catching a person who is participating in a trust fall exercise in a ropes course. The device is constructed of a sheet of strong, flexible material that is provided with straps of reinforcing material, that extend under the sheet from side to side and from top to bottom. Each end of the straps is formed into a loop. The loops at the sides and the top of the sheet serves as handles by which team members grasp the device when catching a person on the device, and loops at t...

Apparatus for guiding and clamping an elongated flexible rope comprises a body supporting a plurality of rotatively mounted guide rollers aligned for guiding said rope in a plane. One of said guide rollers is mounted on said body adjacent a tension end of the rope and is selectively lockable against rotation. The other guide roller is mounted on said body adjacent a portion of the rope that is looped around for tension and is mounted for movement toward and away from said first guide roller so t...

A force reducing device and method for adjusting shutter ropes is provided wherein winding boxes are divided into two sets. Two winding box winding box sets are symmetrically disposed with respect to a center of the upper beam, and each winding box set is fixed with a rope. The two ropes pass through respective holes in the slats, and then wind through a first pulley on the lower beam, and then extend and wind through a second pulley. The two ropes pass upwardly through the respective hole in th...

The present inventive relates to a quick-detachable device for attaching ropes thereto, including a first rope with a hooked end and a second rope with a plain end. The device includes a hollow body having a front opening, a clasp and a chuck both received in the hollow body. The clasp has a ring operable to be turned outward from the front opening of the body for hitching the first rope thereto, while chuck has a first jaw and a second jaw operable to be moved outward from the front opening thr...

The invention is directed to a method for manufacturing ropes, cables or the like, whereby an envelope of a flexible, web-shaped material, for example paper, is produced around at least one central core, for example a conductor, moved in the direction of its longitudinal axis, and the structure that has arisen in this way is stranded in a traditional way while being moved, for example with a SZ stranding, whereby at least one further layer of plastic material can also be applied onto the moving,...

A contact-connecting device connects more than two indicator fibers in an electrically conducting manner to create a conducting connection of the indicator fibers at the end of a safety-monitored synthetic fiber rope made from electrically insulating synthetic fibers and the electrically conducting indicator fibers. A fastener fixes the contact-connecting device and the indicator fibers relative to one another, which creates a low-cost and reliable contact-connection.

A press for splicing the ends of cables, ropes and the like is described. The press is of the type which utilizes an hydraulic cylinder (5) positioned vertically and resting on a base (6). An upper frame (8) comprises a plate (9) which is fixed to the hydraulic cylinder. The piston of the cylinder has a stem which protrudes from the plate. The frame additionally comprises two lateral plates (10) opposite one to the other and arranged in the shape of a "U" and an upper plate (11) which provides s...

Presented is a coupling device designed to release two members that are connected together when more than a predetermined force is exerted to separate the two members. The coupling device is adjustable to increase or decrease the amount of force to which it responds. Structurally, the device includes a plug member having a spherical knob seated in a complementary seat formed in a surrounding tube having longitudinal slits. A sleeve surrounding the tube is slidable between maximum and minimum for...

Tensioning device for chains etc. for lashing, for example, rolling cargo on ships' decks, comprising an oblong housing with a chain- or wire-rope-fastening device at one end, a threaded spindle journalled inside the housing, and on the spindle a non-rotatable sliding piece movable on rotation of the threaded spindle in the longitudinal direction of the housing and guided in it, the sliding piece projecting, with a part fitted with another chain- or wire-rope-fastening device, radially from a lo...
