RIVERLAKE Successfully Completes Critical Bearing Replacement at Australia’s Royal Hills Iron Ore Mine

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.

RIVERLAKE ZJ9 pile load testing power pack is a plc controlled pile load testing system,which can control,display,record and download the real-time pressure of the cylinders,real-time tonnage of the output force,real-time pressure of the power pack,real-time load testing time.In this project,our ZJ9 power station worked with 9 units HCRL30012 double acting lock nut hydraulic cylinders to generate a Max. total output force of 2700 tons.Beside above features,we can even built in bluetooth load cell and bluetooth dial gauge sensors to our pile load equipment to display and record the real-time load data from load cells and real-time pile displacement data from the dial gauge.

Hydraulic cylinders are widely used in engineering machinery, machine tool equipment, automobile manufacturing, metallurgy and mining, aerospace and other fields. So, how are hydraulic cylinders produced? 1. Preliminary preparation 1.1 Design Hydraulic components and sealing components have different requirements in terms of dimensional tolerance, surface roughness, shape and position tolerance, etc. Therefore, the geometric accuracy of each component must be ensured and the correct seal must be selected during design. 1.2 Steel material selection: Commonly used steels are #20 steel, #45 steel, and 40Cr. The hardness of the steel is different, the applicable working conditions are different, and the price is also different, so comprehensive consideration is required. 2.The Production Processing 2.1 Cylinder body Generally, seamless steel pipes without bending or deformation are selected. In order to ensure its good toughness and plasticity, it needs to go through a series of processing. Cut the steel pipe into required length. Threads are machined on the inner walls of both ends of the steel pipe. Drill oil holes at appropriate locations and weld oil pipes. During the production of hydraulic cylinders, many processes such as cylinder barrels and piston rods require welding. High-precision welding machines can ensure welding quality.

Project Manager Mr. Igor from our customer in The Czech Republic came to the RIVERLAKE factory workshop for quality inspection of 96 units of 150-ton CLRG series double-acting hydraulic cylinders. Detail tests were carried out to measure the cylinder dimensions, inner and external cylinder appearance, and static and dynamic load testing on a test bench. Everything went smoothly and both parties signed an acceptance protocol.
