Built for production assembly lines, industrial maintenance departments, and manufacturing workstations, the Ingersoll Rand BSDL-35 medium-duty locking spring balancer supports tools weighing 55–77 lbs. while providing a generous 9.85 ft. lift. By suspending heavier tools above the work area, it reduces operator fatigue during repetitive tasks, improves workstation efficiency, and keeps equipment readily accessible throughout the work cycle.
As part of the BSDL Series, this locking spring balancer incorporates a built-in locking mechanism that secures the cable at the desired working position, allowing operators to hold tools at a convenient height without continuous tension. Its aluminum housing, stainless steel cable, and precision cable guidance system promote dependable performance in demanding industrial environments while helping protect valuable tools from accidental drops and unnecessary cable wear.
Type: Locking Spring Balancer | Series: BSDL | Load Capacity: 55–77 lbs. (25–35 kg) | Lift: 9.85 ft. (3000 mm) | Housing Material: Aluminum | Cable Material: Stainless Steel
Features:
- Integrated locking mechanism holds the suspended load at the selected working height for improved positioning during assembly and maintenance tasks.
- Safety device helps prevent the supported tool from falling in the unlikely event of spring failure.
- Upper suspension incorporates a rotary safety hook for secure mounting while allowing smooth balancer movement.
- Precision cable winding system minimizes cable overlap and helps prevent jamming during extension and retraction.
- Anti-friction cable guide promotes smooth cable travel while reducing wear over extended service.
- Worm screw adjustment allows the spring tension to be matched to the supported tool weight for balanced operation.
- Cable condition can be visually inspected without disassembling the balancer, simplifying routine maintenance.
- Replacement cable can be installed without complete balancer disassembly, reducing maintenance time.

Applications:
- Supports heavier pneumatic and electric assembly tools used on manufacturing and production lines.
- Suspends maintenance equipment in industrial repair and service workstations to reduce repetitive lifting.
- Improves ergonomics during fabrication, machinery assembly, and mechanical installation tasks.
- Keeps larger handheld tools organized, elevated, and within easy reach throughout the work cycle.
- Suitable for production environments where consistent tool positioning and reduced operator fatigue are priorities.
FAQs:
- Q: What is the purpose of the locking mechanism?
A: The locking feature allows the cable to remain at a selected height, helping operators position heavier tools more precisely during assembly, inspection, or maintenance work. - Q: How should I select the correct spring balancer?
A: Choose a balancer whose rated capacity matches the total weight of the tool and any attached accessories. The BSDL-35 is intended for loads between 55 and 77 lbs. - Q: Can the cable be serviced if it becomes worn?
A: Yes. The balancer is designed so the cable can be replaced without fully disassembling the unit, helping minimize maintenance downtime. - Q: What types of tools can this balancer support?
A: It is intended for pneumatic or electric tools and similar equipment weighing between 55 and 77 lbs. that benefit from suspended, ergonomic operation.
