Leveling Cylinders Frequently Asked Questions
What are leveling cylinders?
Hydraulic leveling cylinders are used to stabilize a working platform. Also known as outriggers, stabilizers, leveling jacks and landing gear, they provide a stable base by distributing the load over a wider base. In short, it's a device that helps keep your machinery level, stable, and safe. Leveling cylinders come in various sizes and capacities, so it's important to choose one that's appropriate for your needs.
What are the advantages to mechanical vs hydraulic locking leveling cylinders?
A mechanical locking leveling cylinder can achieve a compressive load strength 3-5 times the lifting capacity with zero deflection. A hydraulic locking leveling cylinder provides ease of use and reduced setup and tear down time.
What is the difference between a leveling cylinder regular nut and split nut?
Both styles of nut offer the ability to mechanically lock a cylinder at a specific extension. A standard nut is a solid, single piece machined from high tensile strength material. A split nut is very similar but split down the centre and hinged allowing for faster setup and tear down.
