Move loads of up to 999 kg at the touch of a finger

Intuitive balancer for improved ergonomics and safety.

The servo-pneumatic balancer allows employees in assembly and logistics to lift and move heavy loads effortlessly at the touch of a finger.

Ergonomics improves efficiency: a servo-pneumatic balancer allows employees in assembly and logistics to lift and move heavy loads effortlessly at the touch of a finger. At the heart of the balancer is the powerful and reliable drive solution YHBP from Festo with automatic weight detection and safety up to Performance Level d – perfect for the automotive and packaging industries.

The system automatically detects the weight of the load and adjusts the balancing force itself, even when suspended loads are added or removed. This makes production processes with a large number of variants much more flexible. And operation is child's play thanks to intuitive control using a pneumatically activated, ergonomic handle.

Playing it safe

Ergonomics must always go hand in hand with machine safety. The safety variant of the drive solution achieves Performance Level d thanks to dual-channel speed monitoring and power shutdown. This ensures it is always brought to a safe state in the event of a faulty component. Dangerous movements are also prevented if there is a voltage failure or sudden drop in pressure.

The pre-assembled servo-pneumatic drive solution consists of a pneumatic ISO cylinder, a displacement encoder, a balancer valve unit, a pneumatically operated handle and a balancer controller. The controller comes with pre-installed balancer software with browser-based web visualisation for commissioning and diagnostics. A sensor interface and a safety relay acting as a speed monitor are optionally included in the package for safety applications.

When configuring the system, users simply choose the required safety Performance Level (b or d) and define the stroke and diameter of the working cylinder. This is really easy using the configurator www.festo.com/YHBP-configuration.

Kinematics and applications

The drive system has proven to be versatile and flexible, making it suitable for installation and retrofitting in all conventional balancer kinematics like lifting columns or parallel kinematics, regardless of whether they are standing or hanging.

In the automotive industry, balancer systems can be used to move and precisely adjust heavy components, for example when fitting shock absorbers, motors, dashboards, tyres, windscreens, doors and seats. In the food and electronics industries, they handle the loading and onward transportation of heavy containers, packages and goods.

In the packaging industry, the focus is on conveying rolls of paper and film, and automated loading and repositioning of pallets. Similar applications can also be found in general machine and system building, in toolmaking, and in domestic appliances, heating and air conditioning engineering.
