The Loading Bench by Mountz Inc. is a laboratory grade instrument designed to enable accurate torque wrench calibration with less physical effort. The Loading Bench simulates torque application conditions with minimum effort and enhanced safety for the calibration technician assuring a more accurate calibration. The calibration instrument enables quick and easy torque wrench calibration and presetting, independent of human influence or transducer side and end load factors. The Mountz Inc. Loading Bench is designed to calibrate torque wrenches in accordance with International Standards ISO6789:2007.

The drive system of the Loading Bench assures the load application eliminates potential operator induced test errors. Built for durable use, the Loading Bench reduces the operator effort required to attain and sustain torque during the calibration process. The Loading Bench features a large handle wheel, which operates in clockwise and counterclockwise directions to allow smooth manual loading.

A torque wrench is considered a measuring tool and must be properly calibrated and maintained on a preventative maintenance and calibration schedule. The adjustable design of the Load Bench allows it to accommodate various size torque wrenches that can be tested with the unit. The gearbox design of the Loading Bench allows for high torque to be applied with minimum effort required from the calibration technician.

Small torque tools go out of calibration with use. To maintain consistent accuracy, small torque tools must be checked periodically for wear or defective parts. A small power or hand torque tool is a measuring tool that must be properly calibrated and maintained.

Mountz, Inc., a specialist in the design and manufacture of torque control products, offers the LPX torque sensor for testing small torque tools. The LPX is a low torque sensor designed for calibrating and testing small hand screwdrivers, torque wrenches and power tools. With it’s with low profile design, the calibration instrument can be used for automated applications, by mounting it to a palletized system. This saves time as there is need to remove the driver from the robot or off the automated system for calibration. These versatile torque sensor is used in conjunction with a torque tester. Mountz offers various LPX models covering a torque range from 1 inch-ounce up to 20 inch-pounds.

In the manufacturing and assembly world, tightening, controlling, or measuring torque fasteners is imperative for production efficiency. An inadequately torqued fastener can vibrate or work loose; conversely, if the tension is too high, the fastener can snap or strip its threads. Faced with these problems, manufacturers are realizing that precise torque control can spell the difference between a safe, reliable, and economical product and complete disaster.

Using a quality torque sensor and torque tester has become increasingly important for many companies to ensure that proper torque is being applied. Testing torque is a science and not something that can be left to chance.

A manufacturer of large industrial gas engines had a torque application for fastening an industrial engine block in a washing chamber after the milling process. The large gas engines are designed and built for demanding applications in waste water treatment plants, power plants, oil & gas fields and other energy applications all over the world.

The engineers were using impact wrenches for the fastening application, but the impact tools were damaging the threads in the engine block due to the lack of proper torque control. An impact wrench is destructive by nature with its “hammering” design. These tools are not ergonomically friendly to an operator and require a high maintenance budget.

A hydraulic wrench was the next tool that the engineers tried using for the fastening application, but it was increasing the manufacturing time significantly and increasing costs. Hydraulic wrenches are notorious for their heavy ratchets, bulky compressors and laborious operation. Hydraulic tools operate through a hydraulic ram that extends and retracts, ratcheting the head. This is a long and tedious process that requires the operator to activate and stand by the pump with a hand-held controller.

The engineers contacted Mountz Inc. and inquired about other cost effective torque control solutions that were available to resolve their fastening application. Mountz demonstrated the CLDpneumatic torque multiplier as an option to resolve their critical torque application issue. The CLD torque multiplier shuts-off when the pre-set torque is achieved. It’s a non-impacting tool and operates at a smooth, continuous rotation. The engineers approved the torque multiplier for their application.
