Zero-Gravity Tower Spring Balancer

Inside the zero-gravity tower spring balancer, the coiled spring is pre-tensioned to the tool weight, and its output force basically cancels gravity across the travel, creating a “zero-gravity” state: ① adjust the tension with the knob to the actual weight; ② after release the tool stays where it is, with no sagging and no spring-back; ③ it can be moved with one hand, keeping the working posture stable; ④ the built-in fall-arrest device locks the wire rope if anything goes wrong with the spring. For a trial, we recommend mounting your actual tool and running a full shift — the effect of tension adjustment is most obvious on site.

Features of the zero-gravity tower spring balancer:

1、Thickened alloy housing

Baked enamel finish, drop-resistant and wear-resistant — the thickened alloy housing reduces body weight while remaining wear-resistant and durable

2、Alloy steel hook

Equipped with a safety latch to prevent detachment; drop-forged high-strength alloy steel hook with strong load capacity, safe and durable

3、High-quality aluminium tower wheel

High strength and better wear resistance — a built-in imported self-locking control system delivers precise control and easier operation

4、Adjusting bolt design

Paired with a thickened locking pin — the thickened adjusting bolt is marked with + / − signs to adjust force, and works with the locking pin for easier use

5、Anti-rotation wire rope

The zero-gravity tower spring balancer has a galvanised surface, anti-corrosion and rust-proof — the reinforced wire rope offers high toughness, fatigue resistance, a long service life and is not easy to break

FAQ

Q1. How do I determine which model to choose?

A: Three steps — first weigh the actual tool weight (including air hose, cable and quick-change head), then allow a 15–20% margin on top of that weight, and finally determine the travel according to the upper and lower limit positions of the workstation.

Q2. My tool weight falls right between two models — which should I choose?

A: Choose the larger rather than the smaller. A slightly larger model can be adapted by dialling the tension knob down, while a slightly smaller model runs at full load over time and shortens the service life of the coiled spring.

Q3. My workstation needs lateral movement — will it work?

A: Yes. A slide-rail trolley or a jib rail enables horizontal movement.

Q4. How long does the coiled spring last, and how do I maintain it?

A: Service life depends on operating frequency and load margin; running at full load will significantly shorten the replacement interval. Routine care only requires checking the wire rope for broken wires and kinks, deformation of the housing, and whether the locking device still works; once it reaches the end of its life, replace the coiled spring assembly.

Q5. Can travel, colour and logo be customised? How are minimum order quantity and lead time calculated?

A: The zero-gravity tower spring balancer supports extended travel, chain versions, anti-corrosion/high-temperature treatment, and OEM/ODM customisation of colour and logo are supported. Custom items carry a minimum order quantity requirement, and lead time is confirmed after drawing approval; standard models are kept well in stock, so off-the-shelf lead time is shorter.

Q6. What is the safest way to place a first order?

A: We recommend starting with a 1–2 unit sample order: mount your actual tool and run a full shift to verify the tension adjustment effect and the improvement in cycle time, then move to a bulk purchase by workstation count to obtain stepped pricing. Once specifications, quantity and lead time are confirmed, you can place the order; repeat orders have corresponding records on file, so lead time is faster.
