When it comes to accurate measurements, precision has a massive role to play. Well, one of the most effective devices to offer you precision motion control is the rotary absolute encoder. With resolutions that go up to 25-bit, absolute encoders offer incredibly accurate angular measurements. And that’s the degree of precision, automation, robotics, and semiconductor manufacturing industries need.

Selecting an absolute encoder for any application can be difficult.  There are many mechanical and electronic parameters.  The part number possibilities can be in the millions.

Overview

Truck Mounted Cranes are an indispensable tool on many construction sites. The compact dimensions and mobility of the truck allow the crane to be driven to the work site and set into position. Although the crane may appear small on the truck, once the support system and telescopic mast are extended, it becomes an impressive piece of transport machinery. The operating range of the booms on these types of cranes was once much more restricted, but today, PLC controls and absolute encoder technology ensure that the boom can be pushed to its limits.

Absolute encoder technology is used on truck mounted cranes to increase the range and accuracy of positioning the boom, and to increase safety. Absolute encoders are used as part of the safety system that locks the crane automatically before the system reaches critical limits.

Overview

Container Cranes are a common sight at ports.  What's new is their improved automation to ensure higher performance and operator safety.

To ensure higher performance, OEMs install absolute encoders, typically 4 units:

• Each main hoist motor (x2)
• Trolley
• Boom (angle)

OEMs and end-users are depending on the absolute encoders--typically the main hoist encoder positions are compared in software--if there is any difference, the crane will shut down.  Likewise, accurate boom angle and trolley position is critical. Errors can result in crane malfunctions or shutdowns.

Overview

Crawler cranes are a common site on construction sites.  What's new is their improved automation to ensure higher performance and operator safety.

To ensure higher performance, OEMs install absolute encoders, often on the winches for boom control and/or hook position.
