Hydraulic systems are at the heart of mobile crane functionality. Whether the crane is lifting, extending, or moving, the hydraulic oil ensures that the machine operates smoothly. The correct hydraulic fluid helps prevent stuttering, maintains consistent pressure, and reduces wear and tear, all of which are essential to avoid costly downtime.
Mobile cranes are equipped with powerful gear systems that require robust lubrication to handle the high stresses of daily operations. Fuchs gear oils are specially formulated to reduce friction, minimise wear, and extend the life of critical gear components.
Synthetics
As these cranes evolve, the demand for synthetics in gear oils has increased, with Fuchs adapting its range to meet these needs. The move towards synthetic gear oils ensures that gear systems can handle the increasingly complex demands of modern mobile cranes.
Grease is vital for the lubrication of moving parts, particularly the crane’s boom and pivot points. Fuchs’ Renolit grease range ensures that booms extend and retract efficiently, even in harsh environments. The company’s Stabyl TA, a white grease, is gaining popularity due to its environmental benefits. Fuchs Lubricants SA’s sales representative, Freddie Eloff, says, “This product serves as an environmentally friendly option that can be easily seen on the machine, ensuring that it is applied properly to reduce friction.”
Black grease
For operators who work in harsh conditions, the company also offers Renolit FLM 2, a black grease that works effectively in more demanding applications. These greases provide crucial lubrication to ensure the crane’s boom operates smoothly, increasing its lifespan and reducing downtime.
“Crane motors may idle at capacity for extended periods, and using a reliable engine oil prevents any differentiation in performance. Poor-quality engine oils, however, can lead to reduced productivity, damage to the system, and more frequent maintenance,” Freddie explains.
Engine oil
Mobile cranes are equipped with powerful engines that demand high-quality oils to keep them running efficiently. Fuchs’ engine oils, such as 15W-40 CI-4, have been a mainstay in the industry, but with the ongoing evolution of machinery, newer formulations such as CK-4 and 10W-40 graded oils are increasingly in demand. These advanced oils provide enhanced protection against fuel dilution and contamination, common challenges for engines that idle for extended periods.
The right engine oil is crucial for protecting components from wear, reducing fuel consumption, and ensuring that the crane’s engine operates smoothly over time. Freddie highlights the importance of selecting lubricants with the right additive packages, particularly for cranes that experience long idle periods and high temperatures, common in South Africa’s climate.
Hydraulic coolants
Fuchs also offers a range of specialised products for crane maintenance, including advanced coolants and non-fling rope dressing. Hydraulic coolants play a vital role in maintaining the proper temperature and preventing overheating, ensuring that the crane’s hydraulics function effectively. The right coolant also prevents engine damage from prolonged idling, an essential consideration for cranes that may sit stationary for long periods while still under load.
Furthermore, Fuchs’ NF (non-fling) rope dressing is designed to protect crane cables from corrosion and friction, even in harsh weather conditions. This rope dressing sticks to the wires and prevents the lubricant from flinging off, offering lasting protection and reducing the frequency of maintenance.
Informed decisions
What sets the company apart is its ability to offer a complete lubrication package for mobile cranes. “We provide a one-stop solution for all lubrication needs, from engine oils to greases and hydraulic oils,” Freddie concludes.
In addition to providing high-quality lubricants, Fuchs offers services such as lubricant condition monitoring. This service includes lubricant sampling and analysis, which helps crane operators monitor the performance of their equipment and allows them to make informed decisions about maintenance.
