Counterweight drilling rig wikipedia counterweight

A counterweight is a that, by applying an opposite force, provides balance and stability of a . The purpose of a counterweight is to make lifting the load faster and more efficient, which saves and causes less on the lifting machine. Counterweights are often used in (elevators), and rides. In these applications, the expected load multiplied by the distance that load will be spaced from the centr. [pdf]

FAQS about Counterweight drilling rig wikipedia counterweight

What is manual counterweight rigging?

Manual counterweight rigging uses a counterbalance arbor equal in weight to the objects being raised or lowered. When balanced, almost any operator can move the line set while still maintaining control. As stage draperies, lighting, video, sound, or scenery change from production to production, so can the weight balance.

How does counterweight rigging work?

Here is a breakdown of each counterweight component of the rigging system and how they work together. Manual counterweight rigging uses a counterbalance arbor equal in weight to the objects being raised or lowered. When balanced, almost any operator can move the line set while still maintaining control.

What is a counterweight used for?

A counterweight is also used in many rotating systems to reduce vibrations due to imbalances in the rotating assembly. A typical example is counterweights on crankshafts in piston engines. Some balanced arm lamps work with a counterweight to keep the arm and lamp in the desired position.

What does a heavy counterweight do in an elevator?

In traction (non-hydraulic) elevators, a heavy counterweight counterbalances the load of the elevator carriage, so the motor lifts much less of the carriage's weight (specifically, the counterweight is the weight of the carriage plus 40-50% of its rated capacity).
