An IP rating denotes a product's ability to prevent the ingress of certain fluids or particles that would negatively impact the functionality of its components. When a piece of equipment is likely to encounter high temperature, high pressure wash down situations and needs to be frequently cleaned without incurring damage, using IP69K-rated equipment is an advantageous solution.

Screw jacks are mechanical devices used to lift and position heavy loads. Operation is manual or fully automated with motor starters, programmable positioning systems, and linear actuator controllers. They are an efficient and versatile alternative to hydraulic jack systems.

Let's look at how screw jacks work, the ways they can be used, and important considerations for selecting the right screw jack system for your needs.

Screw-driven jacks are the most popular devices used to convert the rotary motion of a motor into linear movement. However, there are two common types of screw-driven systems to choose from: ball screws and lead screws. In this blog, we’ll cover the benefits, drawbacks, and applications of both ball and lead screws to help you determine which option is best for your needs.

A screw jack is known by many names — machine screw jack, worm screw jack, lead screw jack, or jack screw — but it has one primary purpose: to take rotational motion and transform it into linear motion. These products allow you to efficiently lift, lower, push, pull, tilt, hold, or otherwise position a load as heavy as 250 tons. Screw jacks' reliability and capacity for synchronization surpass that of comparable alternatives, facilitating a variety of mechanical applications.

The first annual Grand Prix slot car race was held Tuesday, May 14th at a local Hobby Shop.

Our Joyce team competed in racing 1/32 scale and HO scale slot cars. While racers focused on getting the fastest laps and the fewest crashes, the rest of the group served as "Pit Crew" re-setting cars on the track after crashes.

Members of the Miami Valley Council of Scouts BSA gathered to camp on the shores of the Mad River in Ohio to celebrate the 100th anniversary of Scouting in the Miami Valley. 

Despite the inclement weather, these young men and women proved that they were "prepared" for the elements. Our very own Bryan Waid was among the 1500 young people and adult leaders who spent the weekend at camp learning about principles of flight, rock climbing, kayaking, and crossing rope bridges. 

Joyce Lifting & Linear Motion Systems

Joyce/Dayton screw jacks and lifting systems offer wide-ranging lifting and positioning solutions for diverse industries. Our robust jacks reliably move and accurately position loads up to 250-tons. Joyce configures jacks with components such as motors, gear reducers, shafting, coupling, and motion control devices to create complete multi-jack systems.
