Designed for repetitive vertical movement of fixed loads in assembly, production, and service environments, the Ingersoll Rand BMDS-6 Medium Duty Spring Balancer provides an adjustable 8.8–13.2 lbs load capacity and 6.5 ft lift. Its short-cable configuration is suited to workstations where a tool or other supported load travels through a relatively limited vertical range. The spring-balancer design compensates for the weight of the supported equipment, allowing the operator to raise and lower the load with minimal effort.
The BMDS-6 features a cast aluminum body, stainless-steel cable, an anti-friction cable guide, adjustable capacity, and an adjustable stroke-limiting device. The manufacturer also specifies an upper suspension shackle for installation and a safety device against load dropping due to spring breakage on BMDS models above the BMDS-2. The BMDS-6 is specifically rated for loads from 8.8 to 13.2 lbs with 6.5 ft of lift.
