When sensitive products must be positioned, assembled, or joined with precision, the ezzFLOW from Best Handling Technology is the right choice. This intuitive handling system adapts perfectly to the user and the task.
Typical applications include joining and assembling components—for example machines, apparatus, and vehicles, component and subassembly assembly, machine tool loading, support for engines, gearboxes, and couplings, and tool changeover, plus many other precise tasks.

Drive of the ezzFLOWpneumatic balancer
The pneumatic cylinder converts linear motion via a ball screw into rotation used to move a rope. The rope runs over the linear axis and moves the axis carriage; the carriage carries the product gripper and any required rotation.
ezzFLOWpneumatic is a robust, fast solution for many handling tasks. Pneumatic control makes it very fast and especially suited to repetitive cycles typical of automation. All ezzFLOW variants are equipped with optimised end effectors for the task—the right attachment is essential for secure, fast, repeatable picking, designed and built for the product.
The ezzFLOWpneumatic includes a support structure for all moving parts of the automation solution and registers component positions on source and target carriers. The structure is always adapted to pick and place positions and travel path. Best Handling Technology supplies and installs the complete balancer-based system—balancer, end effector, and matching ezzLINK support.
ezzFLOWpneumatic in application
The example above can run as partial or full automation. Three linear axes are included; one, two, or all three can be pneumatically driven. A part is picked from a carrier, moved vertically, and placed on a second carrier. The vertical axis carrying the attachment is pneumatically assisted. On pick-up the part weight is automatically balanced so the part floats when lifted from the carrier. One horizontal axis is pneumatically locked against drift; vertical motion is manual or pneumatic. On placement pneumatic weight compensation switches off.
Linear-axis automation with pneumatic drives is an alternative to six-axis robots—simpler and more robust. For 40 kg handling, a linear system may weigh around 200 kg depending on design; a comparable robot solution about a tonne.
