Atlas Copco’s unique Tensor motors give the Tensor range outstanding spindle speeds and, thus, help you achieve lower cycle times in your operation. Exceptional ergonomics in terms of balance, grip and low weight make the tools a favorite of the operators and increase individual productivity. All Tensor tools are equipped with LED’s that will indicate the tightening result, green light for tightening OK and red light for NOK. At Atlas Copco we believe that quality is the road to lowest cost of operation over time. A maintained Tensor tool produces the same performance year after year at minimum and predictable costs while ensuring highest possible uptime.
The second generation of Tensor tools, Tensor ST, also focusing on safety critical applications, was developed with low weight and productivity in mind.
Accessing tube nuts in deep narrow spaces requires an in-line tool. The in-line attachments are fitted to the tool body in place of the angle head. This results in a smooth assembly tool for tube nut applications. The gears are surrounded by two halves, which even out the forces from the gear train and provide greater accuracy and durability. Tests and real applications show an unrivaled durability for these tube nut attachments.

Features & benefits

  • High speed nutrunner reduces tightening cycle times, thus increasing productivity
  • Improved ergonomics due its light weight for operator comfort
  • Internal bus connection for intelligent accessories, such as a barcode reader and torque selector, reducing time on unnecessary operator movements to read identifiers (e.g.: VIN) or pick up sockets to change program settings
  • Configurable LED’s and an integrated speaker for indicating results via audio signals for operator feedback increasing assembly quality
  • Every gear head is thoroughly tested and supplied with a test certificate to guarantee constant efficiency.
  • The tools and gear heads have no sharp edges, which helps prevent injury to the operator.
  • The run-in procedure for every gear head leads to constant efficiency of the gear, which in turn gives very high accuracy.

Atlas Copco USA - Eco Design
Eco Design and environmental aspects of product development is nothing new to us. Atlas Copco has a history of developing modular tools with a deep respect for materials and natural resources used in the products. We always strive to maximize the functionality of the product and at the same time minimize the energy consumption to make sure the environmental impact is as low as possible. By developing accurate tools we make sure the customer never has to waste time or energy to re-do an operation. For battery tools we also have the option to connect multiple tools to one controller and thereby decrease the standby energy consumption considerably.

Eco Design is all about minimizing a product's environmental impact during its entire life-cycle, including extraction of raw materials, manufacturing, customer usage and recycling while maximizing the productivity.

Our approach to Eco Design

Eco Design
Within Industrial Technique we approach Eco Design from six different areas. These form the core of the Eco Design review performed in each product development project. This procedure helps define Eco Design targets early in the project.
    We avoid hazardous substances and materials listed on the Atlas Copco Restricted & Prohibited list.
    We use materials and structural features to minimize the product’s weight and invest in strong, durable materials to protect the product.
    We avoid mixing materials since blends inhibit recycling and consider fastening methods to facilitate disassembly.
    We consider how the final product will be used in order to minimize energy and resource consumption in the use phase, in production and during transportation.
    We design with recycling in mind. We promote repair and upgrading, especially for long lasting and system-dependent products. To increase the customer’s awareness regarding the importance of recycling, we are now including Recycling Instructions in the Product Information (PI).
    We prepare for upgrading, maintenance and recycling, through labelling, modularization and information in the product information.
This is how we do Sustainable Productivity in practice!
