If you work in manufacturing, construction, auto repair, or any industry that requires repetitive use of heavy power tools, you know how taxing it can be on the body. Lifting and maneuvering heavy equipment for hours on end leads to fatigue, strained muscles, and an increased risk of work accidents. Fortunately, there’s an ingenious yet simple solution that makes using heavy tools nearly effortless – the tool balancer.

At Tecna Balancers, we’re experts in tool and spring balancers and want to provide you with a comprehensive guide on how they work and why your business needs them. Keep reading to learn what tool balancers are, their key benefits, how to choose the right ones, typical applications, and answers to frequently asked questions.

What Are Tool Balancers?

A tool balancer, also called a spring balancer or power tool balancer, is a mechanical device designed to hold a hand tool or piece of equipment in a suspended weightless position. This allows the operator to maneuver heavy tools freely without bearing their full weight or having to set them down between uses.

Tool balancers consist of a spring-loaded reel mechanism enclosed in a housing that attaches to the ceiling, workbench, or wall above the work area via a mounting bracket. A cable extends from the reel and terminates in a hook to which the tool attaches.

The internal spring provides constant tension to counterbalance the weight of the tool. This creates a floating, weightless effect so the tool operator can guide the tool up, down, and side-to-side effortlessly. As soon as the operator releases the tool, the spring automatically retracts the cable, returning the tool safely out of the way.

How Do Tool Balancers Work?

The internal mechanism of a tool balancer that provides the weightless tool effect involves these key components:

  • Housing – A metal enclosure that contains the reel and spring mechanism. Attaches to a fixed mounting point.
  • Reel – Holds the extendable support cable and ensures smooth retraction and extension. Contains ball bearings to reduce friction.
  • Spring – Provides constant outward tension to counterbalance the weight of the tool. Load capacity matches the tool weight.
  • Cable – Extendable steel support cable with low stretch. Connects reel to tool hook.
  • Hook – Attachment point for tool. Swivels to prevent cable twisting.


To set up a tool balancer:

  1. Mount the balancer housing above the workspace via the bracket. Ensure safely secured.
  2. Attach the tool’s handle to the hook at the end of the cable.
  3. Adjust spring tension using the tension knob until the tool floats weightlessly.


The internal spring provides exactly enough upward force to counteract the downward pull of gravity on the tool. This leaves the tool suspended neutrally so the operator can move it freely with minimal effort.

Benefits of Using Tool Balancers

Switching from manually handling heavy tools to using tool balancers provides significant ergonomic, productivity, and safety benefits:

  • Prevents injuries – Eliminates strain from lifting/supporting heavy tools. Reduces repetitive stress injuries.
  • Increases comfort – Work longer without fatigue since tools feel weightless.
  • Saves time – No need to set tools down and pick them back up repeatedly. Faster workflow.
  • Improves focus – Hands-free to operate tools optimally instead of holding weight.
  • Enables precision – Precisely place tools without bearing their weight.
  • Reduces accidents – Tools stored off the ground so no tripping hazard.
  • Protects tools – Tools don’t drop and suffer damage.
  • Optimises space – Tools organised off the work surface to reduce clutter.

For any tasks that involve repetitive use of heavy power tools, balancers make the work faster, safer, and far more ergonomic. Workers stay productive longer with less fatigue.

Choosing the Right Tool Balancer

With capacities ranging from less than 1 kg to over 150 kg and cable lengths up to 3 meters, there’s a tool balancer suitable for any application. Consider these key factors when selecting the right model:

  • Tool weight – Match the tool balancer capacity to the tool weight for proper support.
  • Work height – Determine the mounting height needed to suspend tools in the work zone.
  • Range of motion – Consider tool movement required to select cable length.
  • Work environment – Check if an explosion-proof balancer is needed for hazardous areas.
  • Number of tools – Calculate the total expected load if balancing multiple tools.
  • Portability needs – Some balancers feature removable mounting for portability.

Our expert team can recommend the ideal tool balancers for your unique workspace requirements. We offer a full range of load capacities, cable lengths, mounting options, and special features to create the perfect ergonomic tooling setup.

Typical Tool Balancer Applications

Tool balancers are indispensable equipment in many manual labor fields. Common applications include:

  • Automotive repair – Balancing heavy impact wrenches, drills, and sanders.
  • Construction – Suspending nail guns, circular saws, jackhammers.
  • Manufacturing – Assistance for repetitive tasks on assembly lines.
  • Aerospace – Detailing, machining, and assembly of aircraft components.
  • Machine shops – Offloading heavy grinders, presses, and other metalworking tools.
  • Auto body repair – Easy maneuvering of spray guns during painting prep.
  • Woodworking – Helping guide heavy sanders, routers, and planers.

Any repetitive manual task involving heavy or bulky power tools can benefit tremendously from the addition of tool balancers for ergonomic handling.

Frequently Asked Questions

How much weight can a tool balancer handle?

Tool balancer capacities range from under 1 kg for small pneumatic tools up to 180 kg for heavy industrial equipment. Select a model rated for at least the total weight of the tools to be suspended.

How do I determine the right cable length?

Consider the range of vertical and horizontal motion needed for the tools. Standard cable lengths range from 1-3 meters. Extensions are available. Mount the balancer directly above the work zone.

Can one tool balancer handle multiple tools?

Yes, if the total combined tool weight does not exceed the rated capacity of the balancer. Use a swivel hook divider to split the cable into multiple hookup points.

How long does a tool balancer last?

With proper maintenance, the lifespan is over 10 years. Cable and springs may need occasional replacing depending on use. Units are repairable.

Can I use a tool balancer in an explosive environment?

Yes, we offer ATEX-certified intrinsically safe tool balancers approved for hazardous locations like paint booths. Explosion-proofing prevents sparking.
