Hydraulic cylinders are designed to generate longitudinal force and handle the longitudinal load. But many of these cylinders are also impacted severely by the transverse load. The engineering rule of thumb says that about 10-15% of the hydraulic force is always applied as transverse load, even in the most ideal situation. The mechanical impact of […]
Digging Deeper into Better Reliability for Mega Mining Hydraulic Excavators
In the world of mining, hydraulic excavators are among one of the most important engineering innovations in a new generation of ultra-large “mega” mining machinery designed to increase output and expand production. Because electric rope shovels and hydraulic excavators / shovels often serve and load as many as 8-10 mining haul trucks per day, unplanned […]
Five Tips to Reduce Maintenance Costs for Older Hydraulic Presses
Upgrading cylinder sealing for hydraulic presses can pay off in reliability, longer asset life, and shorter repair time. It’s a common dilemma for the operators of heavy-duty hydraulic systems and press machines around the world: When large diameter cylinders become worn and/or damaged – should you invest in new cylinders or repair the existing ones? While […]
Kaplan Turbine Sealing: Troubleshooting Leakage
About Kaplan Turbines The Kaplan turbine is one of the most commonly used turbines types in hydropower facilities around the globe. This “reaction type” propeller turbine is an evolution of the Francis turbine. It has adjustable blades and/or wicket gates (single- or double-regulation systems) to obtain optimal efficiency in different pressure/head conditions. It operates at efficiencies up to […]
Selecting the Right Retrofitting for Your Mobile Mining Equipment
Those involved in mobile mining know that super-large, hydraulic equipment plays a major role in discontinuous surface mining operation for solid (hard rock) commercial minerals. This includes a wide range of equipment including off-road haul trucks, hydraulic excavators, shovels, dozers, and front loaders. Growing worldwide economic pressures in mining and 24/7/365 schedules have made the […]
