What is a zero gravity lifting arm?

A zero gravity lifting arm is an articulated, pneumatically balanced system that eliminates the perceived weight of the load.

The operator guides the movement with natural ease while the device maintains perfect balance during gripping, lifting, translating and positioning.

Ideal for repetitive tasks, precise placements and delicate components, zero gravity lifting arms reduce physical strain and elevate workplace safety and productivity.

The RHS zero gravity range

RHS offers three main families of zero gravity lifting devices, each fully customizable with dedicated end-effectors:

Handling capacity: versatile, safe, designed for every load

RHS zero gravity machines can be equipped with vacuum tools, mechanical grippers, magnets or combined gripping solutions depending on the application.

They safely handle loads of varying shapes, weights, dimensions and fragility, ensuring smooth, controlled operations in every setting.

Typical Applications

• Containers (liquids, powders, drums, pails)
• Panels (sheet metal, composite, insulation, automotive parts)
• Wheels & Coils (rubber, paper, film, complete wheels)
• Mechanical Components (motors, flanges, assemblies, castings)
• Bags (food, chemical, pharmaceutical)
• Boxes (logistics, warehouses, distribution)
• Glass & Sanitary Ware (delicate slabs, sinks, toilets, bathtubs)

The versatility of RHS zero gravity lifting devices makes them indispensable in a wide range of industrial environments, supporting consistent, safe and efficient handling operations.

Why choose a zero gravity lifting arm for your company?

Choosing an RHS zero gravity lifting arm means equipping your production environment with a solution that enhances safety, optimizes workflows and supports the well-being of your operators. 

Designed to combine precision, ergonomics and human-centered engineering, these systems deliver tangible benefits across every stage of the handling process.

1. Improved workplace safety

Zero gravity lifting arms reduce physical strain and minimize the risk of musculoskeletal injuries.
By stabilizing the load throughout the movement, they enhance safety even in tight spaces or precision-critical operations—creating a healthier, more protected work environment.

2. Higher operational efficiency

Neutralizing the weight of the load makes lifting, rotating and positioning faster and smoother.
RHS systems reduce cycle times, improve repeatability and support continuous workflows without operator fatigue.

3. Better use of human resources

With heavy or repetitive lifting eliminated, operators can focus on higher-value tasks.
This improves productivity, boosts job satisfaction and helps companies retain skilled personnel.

4. Easy to use and easy to integrate

Ergonomic controls and customizable configurations ensure rapid adoption.
Whether column-mounted or ceiling-based, these systems integrate seamlessly into existing or new production lines with minimal training.

5. Technology aligned with Industry 5.0

RHS solutions enhance the operator’s role and promote more sustainable, human-centered production.
Less fatigue, better well-being and smarter resource usage contribute to a resilient, future-ready work environment.
