Spring Balancers for Pneumatic Tools
ENDO spring balancers with integrated air hose that both suspend and supply pneumatic tools, keeping workstations tidy and ergonomic.
Spring balancers with integrated air supply
These balancers solve two workstation problems with one device: the tool hangs weightless at hand height, and the compressed air reaches it through the balancer itself — so there is no separate hose dragging across the bench or the floor. The result is a tidier station, faster tool pick-up and less wear on hoses and fittings. The range covers hand tools up to 6.5 kg: the ATB series (from 0.5 kg) and the THB-A series stepping up to the THB-65A (5–6.5 kg).
Typical users are assembly lines running nutrunners, grinders, drills and screwdrivers — anywhere a pneumatic tool is picked up hundreds of times per shift. For heavier tools or stations without air-fed tools, the standard spring balancer programme goes up to 200 kg, and hygienic areas are covered by stainless food-industry models. Contact us with the tool weight and air consumption and we will confirm the model.
Frequently asked questions
How does the air supply pass through the balancer?
The balancer body doubles as the air feed: the supply hose connects at the top, the tool hose at the retracting side, so the tool's hose travels with the cable instead of hanging in a separate loop. Air passage specifications are stated per model.
What tool weights do these balancers cover?
From 0.5 kg (ATB-0, THB-15A) up to 6.5 kg (THB-65A) — weigh the tool with its fittings and a working length of hose and choose the model whose range contains that weight near the middle.
What if my tool is heavier than 6.5 kg?
Use a standard spring balancer for the suspension and route the air hose separately — the standard ENDO programme covers up to 200 kg — or consider a pneumatic balancer if the task is positioning workpieces rather than suspending a tool.
