What is a pulley support?

Brackets can be used to attach a pulley to a wall or ceiling.

A pulley bracket connects a pulley wheel to a wall or ceiling. There are three basic types of pulley support: those that are eye mounted, side mounted, and top mounted. They are used to give the pulley support and structure, while giving the pulley enough freedom and lightness to operate without reducing the amount of energy it can transfer to the work being performed. This makes support a crucial element of the entire pulley system.

The pulley system is one of humanity’s first machines. It is also considered one of the most simplistic. The word pulley derives from the Greek word ‘polidia’, which means ‘small pivot’. They are used to reduce the amount of energy needed to lift or move an object. Pulley arrangements generally leave one pulley wheel above the other, either directly vertical or more horizontal; this usually requires different types of pulley support to perform.

There are four types of pulleys and several types of pulleys. Each type can vary in size and length depending on the job being done. The four types of belt are cloth, chain, cord and rope. Some types of pulley wheels, such as grooved and pitch wheels, can use either type of belt. Variable speed pulleys, on the other hand, only work with chain belts.

Pulleys work by reducing the amount of force needed to perform a given task. This is achieved by giving one or more pulleys a light feel to reduce friction. The object being moved is then attached to the belt at one end, with the other end being controlled by the operator. The belt is fed through the pulley, which takes the tension and reduces the energy requirement.

An eye-mount pulley bracket tends to hang from the ceiling, but can also be attached to a wall. A hook is hung from the ceiling or wall and a metal handle attached to the pulley wheel is hooked to the eye holder. The eyebolt holder offers more flexibility and is easy to detach and remove the wheel from the pulley if necessary. The downside is that it lacks stability.

The side mount pulley bracket attaches to the wall. This gives you strength and stability, but has less flexibility of movement for the pulley wheel. Due to the restrictions of being on a wall, the pulley is limited to facing forwards or backwards along the wall.

Ceiling or top mounts offer flexibility in terms of the direction the pulley wheel can be turned. It also offers the strength and stability of side mounting. It is fixed in place and, like the side mount, more difficult to dismantle.
