Ingersoll Rand BMDLN-4 Medium-Duty Spring Balancer is designed to support medium-weight power tools and other fixed loads during repetitive vertical movement in assembly, production, and service environments. It provides a 4.4–8.8 lbs load capacity and 8.2 ft lift, giving operators a longer working range than the short-cable BMD Series models. The long-cable configuration helps compensate for the weight of supported equipment so it can be raised and lowered with minimal effort.
The BMDLN-4 features a cast aluminum body, stainless-steel cable, adjustable load capacity, and an adjustable stroke-limiting device. An anti-friction cable guide helps guide the cable during movement, while the upper suspension shackle facilitates installation. The balancer also incorporates a safety device designed to prevent the load from dropping in the event of spring breakage.
