Scissor lifts. JLG scissor lifts are available as both electric and engine-powered. The electric-powered scissor lifts can be used both indoors and outside whereas the engine-powered lifts are used exclusively outdoors in rough terrain and applications that require more workspace and lifting capacity. Telehandlers: JLG, Lull and SkyTrak
An earth-leakage circuit breaker (ELCB) is a safety device used in electrical installations to prevent shock. It consists of either a current sensing mechanism, or a voltage sensing mechanism. Such a protection mechanism may be found in the form of distribution board modules, standalone devices, and special sockets (aka receptacles ).
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...
In 1973, Condor Industries was renamed JLG Industries (JLG for John L. Grove). [ 20 ] [ 21 ] [ 22 ] With innovative products and designs, such as mounting lifts on track-driven frames, locating the crane operators cab on the turret, less expensive truck mounted cranes, and scissor-type lifts, JLG Industries grew to over 700 employees and ...
A simple PoR uses the charging of a capacitor, in series with a resistor, to measure a time period during which the rest of the circuit is held in a reset state. A Schmitt trigger may be used to deassert the reset signal cleanly, once the rising voltage of the RC network passes the threshold voltage of the Schmitt trigger. The resistor and ...
A 3d animated model of a level-luffing crane. A level-luffing crane is a crane mechanism where the hook remains at the same level while luffing: moving the jib up and down, so as to move the hook inwards and outwards relative to the base.
An arc-fault circuit interrupter (AFCI) or arc-fault detection device (AFDD) [1] is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring. Loose connections, which can develop over time, can sometimes become hot enough to ignite house fires.
A jib crane is a type of crane - not to be confused with a crane rigged with a jib to extend its main boom - where a horizontal member (jib or boom), supporting a moveable hoist, is fixed to a wall or to a floor-mounted pillar. Jib cranes are used in industrial premises and on military vehicles.
