What is a cable lifter?
Cable Lifter ( also known as Chain Gypsy, Gypsy Wheel or Cable Holder) is a drum with deep grooves engaged with chain link,have Type A and Type B as per the number of teeth. Type A is Five Teeth Cable Lifter, Type B is Six Teeth Cable Lifter.
How does a windlass winch work?
The winch is powered by an electric or steam-based motor that winds a strong cable around it. The drum on which this cable sits is known as the winch drum. As this drum rotates, it turns a dog clutch, that can be engaged or disengaged by the windlass operator.
How is the cable lifter connected to drive unit?
The drive unit is normally a combined anchor and mooring winch. The drive shaft of the cable lifter unit is in line with the anchor winch main shaft and is connected through a coupling.
What are the parts of a windlass?
The major parts of a windlass are the main shaft, driving shaft, inspection cover, gear, gear frame, drums (one or more), warping head or couplings, brake band, brake liner assembly, chain wheel, gear wheel, pinion, clutch and high-speed, low-speed hydraulic valve blocks.
What is the difference between winch and windlass?
The difference between a winch and a windlass is that the line wraps around and around the cylindrical portion of a winch; whereas the line goes into the forward end of the windlass, passes around the gypsy (cylinder/drum/pulley) and exits out the back (or bottom) of the windlass housing.
What is dog clutch in windlass?
A dog clutch is used to separately engage or disengage each of this unit. All the rotating parts are connected to a motor with the help of a spur gear assembly, which is used to transmit the motor drive to the shaft where various dog clutches enable the power take off.
What’s the difference between a winch and a windlass?
How does a hydraulic windlass work?
Working Principle of Hydraulic Winch Machine The hydraulic transmission uses oil as the working medium, transmits movement through the change of the seal volume, and transmits power through the pressure inside the oil.
How does a cable elevator work?
Cable elevators function on a basic principle where the elevator raises with a traction caused by a cable looped sheave which is in turn linked to an electric motor. As the motor starts turning one side the elevator raises and when the motors turns the other way the elevator is lowered.
How does a traction lift work?
Traction lifts are a simple system. A motor is attached to a sheave (a toothed pulley), with a rope or cable looped over it. The rope is attached at one end to the lift car, and on the other end to a counterweight. When the lift is called to a floor, the motor turns the sheave.
What is the windlass slipping clutch?
What is Slipping Clutch in windlass? Slipping clutch is commonly fitted between prime mover and gearing. It is incorporated with motor, magnetic brake and drive shaft. Set to slip at approximately 133% of full load torque. Letting go or dropping speed is controlled by friction brake.
Why is it called a windlass?
windlass (n.) device for raising weights by winding a rope round a cylinder, c. 1400, alteration of wyndase (late 13c.), from Anglo-French windas, and directly from a Scandinavian source such as Old Norse vindass, from vinda “to wind” (see wind (v. 1)) + ass “pole, beam” (cognate with Gothic ans “beam, pillar”).
How do you use a cable lifter on a windlass?
7.1.2 Windlass is to have one cable lifter for each anchor required to be kept ready for use. The cable lifter is normally to be connected to the driving shaft by release coupling and provided with brake. 7.1.3 For each chain cable, a chain stopper is normally to be arranged between the windlass and hawse pipe.
Cable lifter is the wheel mounted on the windlass shaft provided with five snugs.
How to connect the cable lifter to the driving shaft?
The cable lifter is normally to be connected to the driving shaft by release coupling and provided with brake. 7.1.3 For each chain cable, a chain stopper is normally to be arranged between the windlass and hawse pipe.
How does a windlass work?
Four round pillars at four corners of the base of windlass doubler plate connect to the main deck plating to give continuity of strength to deck The windlass machinery is combined with the forward mooring winch as one unit. The main winch consists of a double reduction gearing arrangement to produce a ;large torque.
