Low Height Pancake Hydraulic Cylinder Used In Auger Boring Steerable Rock System

The hydraulic cylinder often has a jumping and stopping movement state during operation, which we call creeping phenomenon. This phenomenon is especially easy to occur at low speed, which is also one of the main faults of hydraulic cylinder.To solve the problem of hydraulic cylinder creep, we must study the cause of this phenomenon. After summarizing, we found that the cause for hydraulic cylinder creep not only have something to do with the hydraulic cylinder itself and also related to other factors outside the cylinder. Let’s talk about it today. Internal causes of hydraulic cylinder creep failure ① There is residual air in the cylinder, and the working medium forms an elastic body. Troubleshooting method: Fully exhaust the air; check whether the diameter of the hydraulic pump suction pipe is too small, and the suction pipe joint should be well sealed to prevent the pump from sucking air. ② The sealing friction is too large. Troubleshooting method: The piston rod and the guide sleeve are matched with H8/f8, and the depth and width of the sealing ring groove are strictly made according to the dimensional tolerance; if a V-shaped sealing ring is used, adjust the sealing friction to a moderate degree. ③ The sliding parts

From July 15 to August 1, 2025, RIVERLAKE engineers, led by Mr. Bob, deployed to Australia. Working in close collaboration with our exclusive Australian dealer, STRUXIT PTY LTD, the team provided expert training and guided the successful bearing replacement operation at the world-class Royal Hills iron ore mine. The complex procedure was executed using RIVERLAKE’s advanced 8-point synchronous lifting system, ensuring precise alignment and control throughout. The entire operation proceeded smoothly and achieved outstanding results, minimizing downtime for this critical Australian mining asset. This successful project at Royal Hills – a major integrated iron ore mining, rail, and port operation – underscores RIVERLAKE’s expertise in delivering innovative and reliable heavy lifting solutions for the global mining industry. See the project in action! Videos and images from the operation are available below:

Project Images Project Introduction 50-ton low height pancake hydraulic cylinders used in auger boring steerable rock system.Steerable head designed for boring through sand or soft rock with real-time steering adjustments made out of the pit with a hydraulic control system. The Steerable Rock System (SRS) is the auger boring market’s first steerable head designed to navigate not only solid rock but difficult fractured rock conditions as well. Engineered to operate in rock up to 25,000 psi, the SRS allows operators to keep bores online and grade even in the toughest ground conditions for an on-grade bore. On the drilling head, there is peace’s of small round pipe, that’s where the cylinders sit. There are 4 pcs 50-ton pancake hydraulic cylinders on each side(top, bottom, right, and left) of the steerable head for a total of 16pcs, it works when it’s drilling horizontally underground we use the cylinders to navigate the drilling head.
