    Gorbel G-Force Electronic Balancers
      Intelligent Ergonomic Lifting Devices from Gorbel

The Gorbel G-Force™ and Gorbel Easy Arm™ are part of a new family of Material Handling equipment known as Intelligent Assist Devices (IAD's).

The G-Force™ Intelligent Lifting Device uses patented technology and an industrial processor controlled drive system to deliver unmatched lifting precision and speed.

The Easy Arm™ Intelligent Lfiting Arm uses Gorbel's patented G-ForceTM technology and an industrial processor controlled drive system, integrated them into an ergonomic articulating jib design. 


How G-Force Works

The G-Force enables operators to lift and maneuver naturally, as if the device were an extension of their own arm.  The G-ForceTM will help improve productivity, reduce the cost of product damage, and minimize work related injuries. 

The G-ForceTM is available in two series: the BXi series and the streamlined BX Series (lower cost alternative).  Both series are available in 150# and 300# capacities.  The G-Force is also available integrated with our Easy Arm articulating jib crane.


  • Pinpoint precision - speeds from 1 foot per minute (0.3 mpm) up to 275 fpm (83mpm)
  • Blazing speed - travels up to 4 times faster than traditional high end lifting devices
  • Infinite speed control - ideal for applications that require high speed at some points in the cycle and slow, precise movements at other points

The G-ForceTM ILD gives the responsiveness and flexibility of a human operator plus the power of a machine. It incorporates a range of speeds so it is perfect for quick, repetitive motions and slow, precise placements.

New Ergonomic Lifting Study

A new ergonomic lifting study shows that the G-Force outperforms other lifting devices in both high cycle and precision placement applications.  View a PDF copy of the study.

G-ForceTM BXi Series

The BXi model comes loaded with standard intelligence features and programmability to customize it to your application. This series comes in capacities of 150 and 300 pounds.  Higher capacities are available - contact Milwaukee Crane.

Added Intelligence Capabilities:

  • Teachable virtual limits and speed reduction points - unit can be taught to stop or reduce speed when it reaches specific points in its lifting range
  • External inputs/outputs - endless possibilities exist for the I/O on the BXi model. Contact the factory for customized programming to maximize your BXi flexibility.
  • E-stop output - the E-stop can trigger or stop the external system that it is tied to (conveyor, CNC machine)
  • Option to interface with data systems via DeviceNet - external systems that use DeviceNet protocol can read or control the data points and parameters of the G-ForceTM
  • Easily accessible external communications port - any computer equipped with special software can be used to upgrade or monitor performance

This streamlined BX Series is a lower cost alternative for those applications that require the speed and precision of the BXi, but not the added intelligence and flexibility.  Available in 150# and 300# capacities.  Higher capacities available - contact Milwaukee Crane.


  • Float mode capable
  • Inertia management
  • Mimics human motion
  • Precision capability
  • Speed range adjustment
  • Easy tooling integration
  • Operator indicator lights
  • Instant load fluctuation response system

G-ForceTM Easy ArmTM
The Brains of a G-ForceTM , The Body of a Jib 

Easy ArmTM named Plant Engineering 2003 Product of the Year Bronze Medal Winner!

The G-ForceTM Easy ArmTM is the newest addition to our family of Material Handling equipment known as Intelligent Assist Devices (IAD's). We took our patented G-ForceTM technology and an industrial processor controlled drive system and integrated them into an ergonomic articulating jib design. 

Available in 150 pound capacity with standard spans of 6, 8, and 10 feet.

This versatile design is ideal for lifting applications that involve:

  • Reaching under obstructions / low headroom applications-wire goes over a pulley on the beam so you don't lose the headroom taken by the G-ForceTM actuator
  • Reach around obstructions
  • Reach into work cells/doorways
  • Rapid change in direction - you don't have to move the weight of the actuator
