L90 Series (Linear Spring) Loading Arm Counterbalance

OPW Engineered Systems L90 Series Counterbalance has been designed for loading arms that require higher spring loads to accommodate longer reaches and additional equipment. The innovative linear spring design does not require the pneumatic system that is typical for loading arms that have a longer reach or additional weight from attachments. Because all of the calibrations done on the L90 are completed at the back of the spring, the operator is never placed in harms way, and a simple turn of the adjusting bolt provides finite adjustments to tune the loading arm to the desired balance point.
