A turnbuckle, stretching screw or bottlescrew is a device for adjusting the tension or length of ropes, cables, tie rods, and other tensioning systems. It normally consists of two threaded eye bolts , one screwed into each end of a small metal frame, one with a conventional right-hand thread and the other with a left-hand thread.
An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...
Rigging is the equipment such as wire rope, turnbuckles, clevis, jacks used with cranes and other lifting equipment [1] in material handling and structure relocation. Rigging systems commonly include shackles , master links and slings , and lifting bags in underwater lifting.
Diagram 3 shows three rope parts supporting the load W, which means the tension in the rope is W/3. Thus, the mechanical advantage is three-to-one. By adding a pulley to the fixed block of a gun tackle the direction of the pulling force is reversed though the mechanical advantage remains the same, Diagram 3a. This is an example of the Luff tackle.
Aluminium gates, being lightweight, work well with brushless motor operators, as the motors do not have to work as hard to maneuver the gates. This not only enhances the overall performance and reliability of the gate system but also contributes to energy efficiency, leading to cost savings in the long run.
Remote controls send a digital code word to the receiver. If the receiver determines the codeword is acceptable, then the receiver will actuate the relay, unlock the door, or open the barrier. Simple remote control systems use a fixed code word; the code word that opens the gate today will also open the gate tomorrow.
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is overhead line . [ 1 ]
A swageless terminal will work under constant loading and variable shock loading, making it stronger than the wire rope. Regardless of manufacturer the basic principle of operation is the same. The cable has its outer layers wrapped around a metal cone, with the rope's core running through a hole in the middle of the cone. The assembly sits ...
