Practical Hints

 

Another bolting revolution by Hytorc

As has been ever since 1967, HYTORC has invented yet another ‘Super-Tool’ for the industry that will guarantee Safety, Accuracy and Speed in precision-bolting for ‘anything’! According to their agent RASTGAR & COMPANY (PVT.) LTD in Pakistan, this toll can be used for structures; in the Chemical, Textile, Oil & Gas Industry and Power Generation industry, the Military Industry, Steel Mills, Space – you name it! This is just one of its super inventions waiting to be imitated by others!

Small, handy, lightweight, fast and torque-accurate, these are the features of a newly patented pneumatic torque tool - ‘The FLIP™’ from HYTORC, Division UNEX Corporation in Mahwah, NJ. With one hand on the pistol grip and the other on the run-down handle, pre-torque of fasteners for parallel joint closure is accomplished in a Zip with up to 1,800 rpm. Once the flange is pre-torqued, a flip of the wrist turns the run-down handle into a reaction arm and high-speed into high precision torque for a quick and vibration free, precision assembly of all joints.

The FLIP™ is available in 4 sizes for a torque range between 200 and 5,400 ft.lbs. and bolt sizes from  ” to 2” diameter.

Its target market is the industrial market of impact wrenches, the only wrench that up to now provided the speed to get back on line ahead of time. The only wrench pipe-fitters like to use.

However, in the age of ergonomics, the inherent inaccuracy, vibration and the echoing sound of impact guns brought about major changes in recent years causing some companies to ban the use of impact wrenches and switch over to pneumatic torque wrenches.

While pneumatic torque tools are accurate and do neither vibrate or echo, they are slow. Something needed to be done to create a vibration- and echoing free torque tool with the speed of an impact gun.

HYTORC, the inventor of all major improvement in Hydraulic Torque Tools since over 3 decades, took up the task.

From a Safety point of view, dual-speed torque tools are limited to not more than 100 rpm to avoid injury with swinging reaction arms. Safe 1,400 to 1,800 rpm required the same out of the box thinking as it took to reach a given pre-torque for parallel joint closure at high speed with planetary gear systems. Neither is normally feasible.

The standard FLIP-gun has an aluminum motor housing and pistol grip, which for mining is made out of steel.

Its benefits include:

v     No-switch, one tool for safe high-speed rundown and precision torque make-up.

v     Time reduction of at least 50%.

v     Tennis-elbow and Vibration-free Make-up and Break-out .

v     Precision torque within 5%.

v     1 Year, No-Question asked Warranty.
