2700 Ton Pile Load Test

In hydraulic systems, hydraulic cylinders are widely used in a variety of scenarios such as heavy lifting operations, propulsion operations, and driving operations. In these systems, the synchronous operation of multiple hydraulic cylinders is an important part of ensuring the efficient and safe operation of the equipment. The synchronization of hydraulic cylinders can not only improve the efficiency of operations, but also avoid equipment damage caused by inconsistent movement. This article will explore in depth the principles of the synchronous movement of multiple hydraulic cylinders, common synchronization methods, technical challenges, and precautions during operation. 1. Working principle of hydraulic cylinder synchronization Hydraulic cylinder synchronization means that multiple cylinders extend or retract at the same speed and force at the same time. The core lies in the uniform distribution of hydraulic fluid and the precise control of pressure. The realization of synchronous operation depends on the following key factors: Fluid dynamics: The basic principle of the hydraulic system is to use the incompressibility of the liquid to convert pressure into power. The synchronous movement of the cylinder is achieved by controlling the direction and flow of the liquid flow. Load balancing: When multiple hydraulic cylinders share the load, ensure that each

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 Images Project Introduction The North-South Commuter Railway, also known as the Clark–Calamba Railway, is a 147-kilometer urban rail transit system under construction on the island of Luzon, Philippines, primarily in the Greater Manila Area. The project will utilize the Japanese railway system that uses energy-efficient and reliable trains.  RIVERLAKE supplied a pile load testing system consisting of 2 units of 1000-ton hydraulic cylinders and 1 unit PLC-controlled electric hydraulic power unit. The system will perform pile load testing work up to 1569 tons in the NSCR Extension Project. RIVERLAKE PLC controlled hydraulic jacking system is designed for pile load tests up to 2000 tons where the load is to be applied in different stages and displayed accurately in real-time. The plc pile load test jacking system provides 6 default tonnage options, user can preset the loading tonnage and holding period of time for each option. During pile load test operation, the whole process is run automatically, just select one of the preset tonnages and press the auto-run button. the hydraulic jack will raise to its full stroke, upon reaching the preset load, the jacking system will stop automatically and hold the pressure for the preset period of time. The

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.
