Planetary gearbox enables high-precision glass lifting
Back and knees are the areas where most craftsmen experience pain and other discomfort after years of working in the industry. For example in construction where windows and doors have to be lifted and fully adjusted into place before they can be fixed. Employers can choose from a number of tools to help their employees with this task, usually using a forklift or Manitou. Unfortunately, these can only lift, not position the window or door to the wall hole.

Force and precision in one and the same solution
After all, it should not only be able to keep the heavy building element completely solid and stable. It must also be able to adjust the placement of the element in small steps with a remote control so that the glass lifter does not release the element until it has been securely attached to the hole in the wall. It required both force and precision – and these two things rarely go together in practice.
Either an old-fashioned and very cumbersome mechanical solution or an expensive hydraulic system would have to be used for that. The first would make operating the glass lifter very complex, and the second would pose a risk of contamination – and costly cleaning – if one of the hydraulic hoses were punctured. Plus, this wouldn’t make it to precision.
Fortunately, the customer contacted Apex Dynamics and the result is impressive:
Large planetary gearbox in combination with small gearbox and motor
The planetary gearbox type AD with output flange is incredibly strong and can hold up even very heavy window or door elements by means of the four suction cups that hold the element. At the same time, the advanced joystick makes it possible to adjust the element in very small steps. This makes it easy to lift and adjust the door or window element in place – and keep it fully locked during the actual installation.
