What Is the Winch Cab Single Purchase Apparatus Used For?
A winch crab is a geared lifting machine: an effort turns a wheel, and the gearing winds up the load more slowly than the effort moves, so a small effort can raise a heavier load. In the laboratory the student applies a known load, finds the effort needed to raise it steadily and measures how far the effort and the load each move. Dividing load by effort gives the mechanical advantage, the ratio of the distances gives the velocity ratio, and comparing the two gives the efficiency; the double purchase version repeats the test with a second stage of gearing.
What to Specify When Ordering
- Quantity — the number of winch crabs required.
- Version — single purchase or double purchase.
Frequently Asked Questions
What is the difference between single and double purchase?
The single purchase winch crab has one set of gearing, while the double purchase version is built the same way but with a double set of gearing arrangement for additional mechanical advantage.
How is the winch crab mounted?
It is fitted with heavy cast iron wall brackets, so the apparatus is fixed to a laboratory wall for use.
What size is the grooved wheel?
The grooved wheel has a diameter of 25 cm, and the gears of the winch crab are machine cut.
What is measured with a winch crab?
The load raised and the effort applied are measured, along with the distances they move, to work out the mechanical advantage, velocity ratio and efficiency of the machine.
