Ingersoll Rand BMDLLN-4 Medium-Duty Spring Balancer is designed to support compatible tools and equipment during repetitive assembly, production, service, and maintenance operations. It provides a 4.4–8.8 lbs load capacity and 8.2 ft lift, while its long-cable configuration provides extended vertical travel for workstations where supported equipment needs to move through a greater working range.
The BMDLLN-4 is part of the BMD Series of medium-duty long-cable spring balancers. Its spring-balancer design helps counter the weight of the supported load during vertical positioning, while the 8.2 ft lift provides the specified range of cable travel. The 4.4–8.8 lbs capacity makes this model suitable for compatible equipment that falls within its rated load range.

Applications:
- Assembly workstations where medium-weight tools require overhead support through an extended vertical range.
- Production stations using compatible tools or equipment weighing within the 4.4–8.8 lbs capacity range.
- Automotive service and maintenance applications requiring supported tool positioning.
- Manufacturing workstations where longer cable travel is useful for moving equipment between working positions.
- Repetitive operations where spring-assisted support can help reduce the effort required to reposition suspended equipment.
FAQs:
- Q: What is the load capacity of the BMDLLN-4?
A: The BMDLLN-4 is specified for loads from 4.4 to 8.8 lbs. - Q: How much lift does the BMDLLN-4 provide?
A: The BMDLLN-4 provides 8.2 ft of vertical lift. - Q: What does long cable mean on the BMDLLN-4?
A: Long cable identifies the BMDLLN configuration and provides 8.2 ft of lift for applications requiring an extended vertical working range. - Q: What type of equipment can be supported by the BMDLLN-4?
A: The balancer is intended for compatible tools and equipment whose supported load falls within its specified 4.4–8.8 lbs capacity. - Q: Can the BMDLLN-4 support a load above 8.8 lbs?
A: No. The specified load capacity is 4.4–8.8 lbs, so the supported load should remain within that range.
