Winches are designed to pull heavy loads and objects. Bloom Worm Gear Pulling Winches can pull large loads up to 20,000 pounds. There is a lot of science behind it and multiple simple machines that go into a winch to make it work properly. Continue reading to find out more about a few of the different simple machines that make up a Worm Gear Winch!  


There are usually multiple gauges present in a worm gear winch depending on the type of winch and the manufacturer. Each gauge is used for a different function and plays a big role in making the winch work correctly. Gauges can be used to perform many different functions including; pressure of the system power fluid, weight indication, jib rotation motor pressure, and to counterbalance circuit pressure. There usually must be at least one gauge present but there can be multiple 

Main Winch Control  

The main winch control is usually a joystick that has three positions, the joystick is able to control how much rope is being taken up and how much rope is paying out. When the joystick handle is being pulled back, more rope is taken up which is then pulling the object by hoisting it up. When the handle is being pushed forward it allows the object to be lowered. The main winch control is typically made up of two lines and is designed for heavy loads.  


The counterbalance winch control is made up of a single line and is designed for lighter objects. The counterbalance winch control can be controlled by a lever or a joystick and is able to control the speed and direction of the winch. The counterbalance circuit contains a hydraulic brake that is a counterbalance valve, which is where it gets its name. The counterbalance circuit controls the free flow of oil in and out of the motor.  

Jib Extension  

Jibs allow the unit to be rigged up in its retracted position. The hydraulic jib extension is a three-position lever that has an internal brake to prevent extension or retraction while in use. The three positions are forward (which is up), backward (which is down), and center (which is neutral).  

Jib Rotation  

Jib rotation can be done manually or can be done using a hydraulic motor and is usually located on the counterbalance control panel. Jib rotation is not a common feature, it is rare and only used for certain applications. This operation is usually slow speed and doesn’t require speed control. High speed jib rotation is not recommended 

Overall, there are many simple machines that make a winch perform its function correctly. Learning about all of these can be very helpful in understanding how a winch works and how each machine plays an important role in the winch function.
