Synchronous Jacking Options – Which System is Most Precise?
Synchronous jacking is a simple concept in nature: raising an object or structure at the same time to avoid causing damage or failure. There are several methods to achieve varying levels of synchronization. The key is determining the degree of precision necessitated by the project.
Simple Sync Jacking
Many sync lifting projects can be completed with a simple setup. You can utilize manual hydraulic pump/electric hydraulic pump/gasoline hydraulic pump, pressure gauges, and manifolds to accommodate the appropriate number of rams. In that setup, one person stands at the pump and manually adjusts the flow to each ram. These flows are based on the readings taken from the pressure gauges. While this method will keep the load relatively level, the margin of error is considerably higher than other methods.
For projects requiring greater precision, LGH carries a 4-port split flow pump from Enerpac’s SFP Series. This pump provides lifting accuracy of 4%. Split-flow pumps provide a better alternative for projects such as bridge lifting for bearing replacement, wherein the accuracy of the lift is paramount to maintaining the integrity of the bridge. The electric pump can be used to advance, hold, or retract (for double acting cylinders) the load using either a joystick or pendant. It can even operate the rams individually when needed. Split-flow pumps act as an intermediary between manually operated manifolds and the next option, the EVO-Series Sync Lift System.
Sync Lift System
When precision is paramount in your lifting application, look no further than the Enerpac EVO Sync Lift System.
Each EVO-series unit features an intuitive user interface, which provides easy set-up and control with multiple lifting options.This system is designed to handle up to 48 points with unparalleled control. It is compatible with hydraulic cylinders at 10,000 PSI and precise up to .04 inches between leading and lagging cylinders. Thanks to the affixed specially tuned computer, a single operator can effortlessly oversee and ensure accuracy for every ram in your application- all from a central point. At each data feedback point, the controller provides real-time insights into load weight distribution and displays the stroke height for each cylinder, accurately measured by a magnetic sensor. The computer system then uses these sensor readings to modulate the flow of oil.
The Enerpac ESS Sync Lift model is also a great option. The ESS can control up to 24 lifting points, is accurate within 0.040” between leading and lagging cylinders, offers data storage and recording capabilities, load and stroke alarms for optimal safety, and can be used with standard single or double-acting cylinders.
