Ingersoll Rand ZAW040120S Zimmerman ZA Air Balancer – 180 kg, 3 m Travel
Price on request
Zimmerman ZA Series air balancer – the most common choice for fast, precise handling of loads of varying weight. Lifting and lowering are controlled with an ergonomic pendant handle; after positioning the unit automatically returns to a balanced state and the operator can float the load by hand up to 457 mm for final placement. Steel housing, aircraft-grade wire rope, oil-free pre-lubricated piston chamber, continuous duty.
Safety: a centrifugal brake stops rapid cable retraction if the load is lost, the load stays suspended if the air supply is interrupted, and capacity can never exceed the rating at the given pressure. Also available with B (no control, for end effectors), BA (constant load) and EA (up to 3 loads) controls and with suspension for IR ZRA1/ZRA2/ZRAT aluminium rail, ZRS2/ZRS3 steel rail, I-beam or KBK rail. Z-Stop (prevents load drift when the air is shut off) – see specifications.
Capacity at 5 / 6 / 7 bar: 130 / 155 / 180 kg
Lifting travel: 3 m
Wire rope: tandem
Body diameter: 254 mm
Control / suspension: ZA pendant / suspension as ordered
Z-Stop: standard
Weight: 56 kg
Price and lead time on request – we help you select the model, control and suspension and match the solution to a rail system or jib crane.
×No width = single rail; with width = workstation crane (bridge + 2 runways).how often the rail is fixed to the ceiling or support beam; not sure – leave 3 m
4Control
More details (optional)
Above 227 kg no standard model fits – we offer an engineered solution (Zimmerman balancer, manipulator or rail system).
1Rail – Enclosed profile the trolley rolls in. ZRAT, ZRA1, ZRA2 – aluminium, ZRS2 – steel. A larger profile carries more.
2Hanger – Fixes the rail to the ceiling or a beam.
3Rail fixing spacing – How often the rail is fixed to the ceiling or support beam (distance between two hangers along the rail). The larger the spacing, the less the rail carries – the configurator checks this. IR table: 1–9 m.
4Runway length – Total rail length the balancer travels along. Longer runways are built from several rails.
5Splice kit – Joins two rails into one runway – no welding.
6End stop – At both rail ends – the trolley cannot run off the rail.
7Safety cable – Secondary attachment at every hanger (IR requirement).
8Trolley / suspension – Top mounting of the balancer: trolley on a rail (ZRA1, ZRA2, ZRAT, ZRS2), hook mount to an existing hook/beam, or no suspension.
9Balancer and Z-Stop – The Zimmerman air balancer keeps the load balanced. Z-Stop locks the cable drum when air or the interlock is off (standard on some models, an option on others).
10Stroke – How far the hook travels up and down: 2.03 m (3.05 m on the 91 kg model).
11Control – ZA – pendant up/down and float; BA – single fixed load; EA – up to 3 loads (high, low, no load); B – no control, for an end effector or own controls.
12Load – Load = part + gripper or tool; the configurator adds the balancer weight. The hook or end effector is ordered separately to suit the load.
Estimated kit and budget
Capacity at 6 bar line pressure (5 / 7 bar – see product page). IR recommends a working load up to 80% of capacity. We confirm fit, price and lead time in the quote.
Float mode – after positioning, the balancer holds the load in balance so it can be placed precisely by hand, without the hit-and-miss jogging of a hoist
Ergonomic up/down pendant control (3.7 m hose) – fast, precise positioning of variable weight loads
Built-in overload protection – the lifted load can never exceed the rated capacity at the given air pressure
Z-Brake centrifugal brake standard – stops rapid cable retraction if the load is lost; optional Z-Stop locks the load when the air supply is shut off
Low air consumption – about 1/50 of an air hoist; oil-free pre-lubricated design, no air line lubricator needed – also for clean production
Steel housing, ball screw, heavy-duty thrust bearing and low-friction cable guide – continuous duty with minimal maintenance
Capacity 49–450 kg (5–7 bar), 1–3 m travel; hook mount, IR aluminium or steel rail, I-beam or KBK rail suspension; CE
Applications
Pick and place, precision assembly, machine loading and unloading and lifting with end effectors on assembly lines – wherever load weight varies and fast, precise handling is needed without straining the operator’s back and arms.
The balancer can be suspended from a hook, an I-beam trolley or an aluminium rail – see rail system components.
Safety and service
Use only up to the rated load and as per the user manual; installation and regular inspection according to local regulations. The user manual and other documents are on the “Documents” tab. Service and inspection are arranged together with the Ingersoll Rand service team – services.
