OILCO Liquid Handling Systems has consistently been on the manufacturing forefront of loading arm technology, focusing on safety and programmed performance. OILCO engineers pioneered the development of the standardized torsion spring counterbalance over 65 years ago. And for traditionalists in remote areas, a variant of the seven-decade old counterweight unit is still offered in the production line today. Understanding the demanding climate and operating conditions of the industrial terminal landscape, OILCO maintains loader options that serve the vast array of bulk industry applications in a dedicated manner. Whether from above or below, this is true triple threat with vastly different performance characteristics.
The Torsion Spring Counterbalance Assembly
The workhorse of the balancing systems is the torsion spring counterbalance assembly. With more than a dozen available combinations of spring setup, the OILCO Models 640, 641 and 645 allow for a wide range varying field adjustment. The reactionary main torsion springs will allow for changing equipment needs without the need to add or subtract weights within the unit, or replace pre-programmed cylinders. The OILCO torsion spring assemblies are the unquestionable broad spectrum answer to any terminal project.
Developed in the 1960's for the northern California market, the slide weight system was the last evolution in the counterweight design application. Allowing for the longer horizontal reach required for the terminal hose loaders, the Model 773-CWT combined all of the traditional aspects of the bucket style and swing weight units while placing it into a smaller performance profile. Resting on the OILCO Model 857 riser swivel joint, these units, when unaltered have already proven to be able to withstand a half century of service life. Modern variants are available and current design specifications can be met, providing historical reliability to the customer.
