Remote Power

Torque Multiplier

Pipelines that stretch across miles and miles of vast open, remote land transporting liquids and gases require maintenance. Deep below the surface in an underground mining operation, large industrial vehicles or tools require routine maintenance. The large bolts used to securely join sections of pipes and valves together or used with mining vehicles require torque control and power to tightening and untightening these bolts.

Access to power for these locations might not be easily accessible like a power outlet at your home or an air compressor inside a maintenance shop. Remote power is needed. Power for remote locations. A hand torque multiplier is the torque solution. No electricity or air is required to operate the tool. Only the hand multiplier and a torque wrench are needed for the maintenance technician to loosen and retighten threaded fasteners, nuts or bolts.

The gearing design of hand torque multiplier allows for high torque output with minimal input from an operator. A torque wrench is placed into the input drive end of the torque multiplier. A socket and reaction device are used on the other end where the square drive is located. These hand tools feature a torque multiplication ratio, which is different for each tool model and brand. The technician pulls the torque wrench and applies force. The torque output is multiplied by the hand multiplier tool. Requiring less effort and strain for the technician.

The HG hand torque multipliers offered by Mountz are engineered for enduring performance. Mountz offers various hand torque multiplier models with a maximum torque capacity up to 36,800 foot-pounds, satisfying the requirements of even the most demanding MRO applications. Some models include a strong (anti-wind-up) ratchet, allowing jobs to be completed efficiently and safely.

Reduce the Risk of Over & Under Tightening with a Break-Over Torque Wrench

MTBN Break-Over Torque Wrench

In selecting a torque wrench, you need to know the torque required for the fastening application. In general, that seems like common sense. How can you ensure the proper torque is being applied while tightening a fastener or bolt with a torque wrench? By selecting the proper wrench for the assembly application, which can be a little confusing and stressful if not properly trained.

There are a wide variety of preset and adjustable torque wrench options to select. Educating yourself on the different torque delivery mechanisms offered for wrenches is worth learning. With mechanical torque wrenches, there three general types: cam-over torque wrenches, break-over torque wrenches and click wrenches. Each of the three wrench styles has a specific purpose and utility.

Click wrenches typically break at 3 degrees after the preset torque is reached and then the tool becomes positive. Thus, easily allowing for an operator to incidentally apply more force and over torque the fastener. Or intentionally apply more force because of the operator’s mindset is that “more force is good”.

A cam-over wrench removes the operator’s influence from the application as the tool prevents a fastener or bolt from being under and over tightened.  As a quality control tool, the wrench allows any user to deliver the correct torque with confidence regardless of task and operator skill level.

Break-over wrenches improve control of the fastening process by reducing the risk of both over and under tightening. Upon reaching the preset torque value, the tool “breaks” at a specific point along the tool’s shaft – usually at a pivot point near the tool’s head. The unique break-over mechanism, provides an operator ample time to react once the target torque is reached and to stop applying any additional force to the fastener.

Electric Screwdrivers

For companies that manufacture at a low volume production level, often hand torque tools are adequate to meet their fastening requirements. But when production demands increase, a new dilemma is born. Is it time to switch tooling from hand tools to power assembly tools?

Selecting the proper electric screwdriver for a fastening application can be a overwhelming at times. So many options and features being offered in the torque tool market today. Educating yourself and understanding the various electric screwdriver options is key.

Electric torque screwdrivers are designed for precision torque control and ensure product quality, cost savings and a reduction in overall assembly failures. Fasteners that are insufficiently torqued can vibrate loose, and excessive torque can strip threaded fasteners or damage parts. For low to medium volume production fastening applications, the K-Series from Mountz is a quality option to consider.

The K-Series tools are low voltage DC electric screwdrivers. These rugged assembly tools increase productivity and enhance product quality through precision torque control and user comfort. The electric screwdriver automatically stops when the preset torque has been reached. The K-Series electric screwdrivers are NRTL certified from TUV America, Inc. The certification ensures manufacturing companies are purchasing and operating a quality and safe tool for its operators.

Tips for Selecting a Preset Torque Screwdriver

Posted by Mountz Torque December 11th, 2013 0 Comments   
Preset Torque Screwdriver

A preset torque screwdriver is similar to a person setting an alarm clock to signal the achievement of a selected time. The torque screwdriver is pre-set to the required torque value of the application and then the tool signals the operator when torque is achieved. A preset torque screwdriver does not feature an external adjustment scale. These tools have internal adjustment mechanism for setting the torque value and must be preset using a torque tester. Preset screwdrivers are ideal for production applications where there is one torque setting required and you need to prevent incidental or operator tampering of the torque setting. However, if the torque specification changes or new project requires a different torque setting, the preset torque screwdriver is still flexible enough that a new torque setting can be set internally using a torque analyzer.

The cam-over philosophy of each Mountz hand torque screwdriver prevents a fastener or bolt from being under and over tightened. These torque tools ideal are for production applications where over-torque conditions are not tolerated. As a quality control tool, the torque screwdriver allows any user to deliver the correct torque with confidence regardless of task and operator skill level.

The design action of the cam-over torque screwdriver is such that when the tool reaches its preset torque value the mechanism disengages from the drive thus limiting the torque applied. Also, the thrust bearings insure that the torque setting is independent of any end load applied by the operator. Designed for variety of industries like medical, aerospace, semiconductor, electronics, and communications, a Mountz preset torque screwdriver ensures proper torque control. Featuring a tamper-proof internal adjustment, the Mountz preset torque screwdrivers have no external adjustment scale and must be pre-set using a torque tester.

Versatile Dial Wrench is a QC Tool Used for Both Assembly Applications & Torque Auditing

Posted by Mountz Torque December 4th, 2013 0 Comments   
Dial Wrench

A dial torque wrench is typically used as a quality control instrument to verify or monitor torque. What is a dial wrench? A type of wrench that measures the amount of torque applied to a fastener and displays the torque value on a dial. The dial wrench captures the finishing torque applied to a fastener with a memory pointer.

The versatile dial wrench can be used as an assembly tool for fastening applications or as a quality control tool for joint testing, torque auditing or torque verification. These old reliable tools are suitable for use by operators of any skill level. For fastening applications, an operator can clearly monitor the torque applied. Some dial wrench models feature an audio and visual signal system, which provide a clear indication to the operator when the target torque has been reached. For torque auditing applications, a dial wrench is alternative solution to a digital wrench for conducting a quick visual torque verification test.

Torque Auditing After the Assembly Process
Torque measurement is paramount for many manufacturers. Simply running a fastener or bolt down until it’s snug and tight and assuming the torque control process is complete, is no longer sufficient. Measuring torque doesn’t stop once the assembly process is complete. As part of the overall quality control process, manufactures should include a “Torque Auditing” program. A method to detect loose fasteners or any signs of joint relaxation. Torque auditing validates the fastening process, the torque tool, the product design and the materials used for the application.
