For lifting and moving loads of multiple sizes, many aerial lifts rely on hydraulic lift cylinders – part of their comprehensive hydraulic systems. On scissor lifts, hydraulic cylinders raise and lower the platform. In addition to performing a similar function for the boom itself, hydraulic cylinders also support turntable and platform positioning and leveling, as well as the extension and retractions of different components, on boom lifts. In short, a hydraulic lift cylinder plays an important role in multiple aerial lift operations. In this guide, learn more about how hydraulic lift cylinders work, the importance of their maintenance and where to find the necessary replacement parts to keep your aerial work platforms functioning smoothly.
How do hydraulic lift cylinders work?
Hydraulic lift cylinders are key components of an aerial lift’s hydraulic system. When pressurized fluid is directed into the hydraulic lift cylinder or released from it, movement occurs. In addition to vertical movement as with scissor lifts, boom lifts may leverage the benefits of different types of hydraulic lift cylinders for even more functionality, such as single-acting and double-acting cylinders, telescopic cylinders and welded cylinders. The specific types used in a particular aerial lift relate to characteristics like lifting capacity, vertical and horizontal reach and other operational needs.
Why is maintaining hydraulic lift cylinders important?
Hydraulic lift cylinders support the smooth movement and positioning of platforms and booms that make these aerial lifts vital to industries ranging from construction to retail to entertainment. In addition to key features of lift operations, newer hydraulic lift cylinders may also support a variety of safety features, such as load and tilt sensing. Accordingly, regular maintenance and inspection of the hydraulic system, including hydraulic lift valves helps ensure equipment availability and the safety of the operators and worksites. Here are 3 key checkpoints that contribute to hydraulic system performance:
- Hydraulic fluid level and quality: Contaminated fluid and fluid leaks can cause a number of problems including damage to individual aerial lift components as well as operational failures. Consequently, daily visual checks and more thorough fluid evaluations, not to mention scheduled fluid replacements, are crucial.
- Seals: Regular exposure to high heat and chemicals may cause immediate issues or result in complications over time. For example, compromised seals may cause changes to or a loss of hydraulic pressure.
- Hydraulic lift cylinder: Aerial lifts work hard, and hydraulic lift cylinders enable them to consistently and powerfully do so. From wear and tear to unexpected damage from other materials or equipment, cylinder damage can lead to hydraulic pressure loss, fluid contamination and other operational complications.
How to Find Hydraulic Replacement Parts
Whether you need replacement hydraulic parts or new battery chargers, Aerial Equipment Parts offers replacement parts for many types of aerial work platforms. Search our extensive inventory of aftermarket parts that fit a variety of aerial lifts from multiple leading AWP brands including JLG, Skyjack and Genie. Alternatively, simply contact our expert U.S.-based team for assistance in sourcing the right replacement part for your specific equipment. Check out a sample of our collection of replacement parts below:
121090 Seal Kit for Skyjack
When the steer cylinder is leaking on a scissor lift like the SJ-3219, a replacement seal kit may be a less expensive repair option than having to replace the entire hydraulic lift cylinder. Make sure to confirm that a chosen aftermarket replacement part corresponds to your lift’s serial and model number to ensure that it is the one you need for your machine.
120220 Brake Cylinder for Skyjack
In addition to seal kits, worn or damaged filters and valves and coils can also compromise hydraulic lift cylinder performance. If you find that there is an issue with your hydraulic motor or that your hydraulic lift cylinder has more extensive damage, AEP also offers new aftermarket replacement parts like this 120220 Brake Cylinder for Skyjack.
Drip Diapers
Floor protection is essential for worker safety and for reducing potential damage to any interior flooring on which aerial lifts may be used. Damage to both building floors and to AWPs, not to mention slip hazards, often stem from fluid leaks, including those that may come from the hydraulic system. Drip diapers, such as this 1930 drip diaper that fits JLG, fit under the belly of the AWP and can help absorb any hydraulic oil leaks.
Tires
When hydraulic lift cylinders are functioning as they should, they help facilitate movement and the stability of aerial lift features, like platforms. Tires serve a similar purpose. If tires have sustained damage or simply need replacement due to wear and tear, find new aftermarket replacement tires, like this 105122 tire that fits Genie scissor lifts, and a number of other options for a variety of AWP makes and models.
