Spring balancers are industrial tools used to suspend products andequipment to reduce the weight burden on workers andallow precise maneuverability of suspended tools and loads.

There are three types of tension adjustment systems. The adjustment system depends on the model. (The springtension has been set at the middle of capacity in advance prior to shipment)

Read the instruction manual carefullyfor instructions.

Travel(m)If the spring fails the pin is activated and prevents the suspended tools from falling.

P.6

By changing the position of the pin, you can lock the drum and change out the tools or wire rope easily and safely.

P.7〜8

The secondary support hanger is standard on every model.

tool on the stroke mechanically.
Even if no load is applied, its
hook can be held on the stroke.

Spring balancer with brake system
Features
The EWA special model is equipped with a ratchet device on
the spring case that prevents sudden snap back retraction of
the wire rope if the wire rope fails, is cut, or if the suspended
tool is disengaged.

The braking balancer is equipped with a one-way clutch that slows
retraction but doesn’t interfere with extension. This feature can also be
set to off to use the balancer without the brake.

If the spring fails the fall arrest device activates and prevents
the suspended tool from falling.
The inside diameter of hose is 8.5mm which supplies enoughair to operate the suspended air tool or device.

Inplace of the wire rope, the urethane hose is wound and air
tools can be easily moved up and down.
The casing and drum are made of acrylonitrile butadiene-styrene
resin and are light weight.
The diameter of the hose nipple is 9mm at inlet portion.
And swivel joint size Rc.1/4 at outlet portion.

The spring works to retract a hose into the device automatically.
The 10mm inner diameter of the hose allows lager air tools tobe operated.
A ratchet system installed to the device can keep a toolsuspended at any position on the hose travel length.
※On-off work of ratchet system is available through knob operation.
The fall preventive system activates if the spring fails.
ATR-5 is installed with top hook and ATR-5-1 is installed with bracket.
