The TECNA 9336/4,5 is a long-reach industrial spring tool retractor - a retractor tool balancer for tools weighing 4.4-8.8 lb, for example drills, small nutrunners or riveting tools - and it works equally with any other tool in that weight range.

Cable travel is 14.8 ft (4,500 mm) and capacity is adjustable across 4.4-8.8 lb (2-4 kg). It is a retractor, so when you let go the tool returns to its rest position, clear of the work, rather than staying where you leave it. A spring drum inside winds the cable in and carries the tool's weight, which is why retractors like this are also called spring balancers. Hanging the tool takes its weight off the operator's arm, which cuts fatigue on repetitive assembly-line work, and keeps the tool, and its hose or cable, off the bench and off the floor, so they last longer.

This is the long-reach version: 14.8 ft (4,500 mm) of cable travel against 8.2 ft on the standard TECNA 9336, for stations where the tool has to come a long way down from a high mounting point. Capacity is the same.

Need the cable to stay put so you can work with no upward pull on the tool? The TECNA 9346/4,5 is this same retractor with an automatic ratchet lock, at the same capacity and cable travel.

If the drum spring ever breaks, a safety device blocks the balancer so the tool cannot fall. If it trips, do not try to free it - have the balancer serviced.

Size it on the total hanging weight - the tool, its accessories and the length of hose or cable the balancer lifts - which has to sit inside the capacity range. Electric, pneumatic and hydraulic tools all suspend the same way.

The structure you hang it from has to be stronger than five times the balancer weight plus the maximum load - and if several balancers share one structure, five times the total of all of them, each on its own independent connection point. Always connect the safety suspension to a separate support, and set the stroke limiter so the tool never comes to rest above the operator.

Made in Italy, to DIN 15112. Breaking load is guaranteed at a minimum of five times the declared maximum load on every sensitive part. Every production lot is sample-tested too: a static test at 1.25 times the maximum rated load held for ten minutes at full stroke, and a dynamic test at 1.1 times maximum load run for an hour.

Other long-reach models in the same series: 9337/4,5 (8.8-13.2 lb), 9338/4,5 (13.2-17.6 lb), 9339/4,5 (17.6-22 lb), 9340/4,5 (22-31 lb).
