Bolt tightening is an old age technique that is used in fastening parts of machines and other equipment together. Despite the increasing state of innovations that have reformed the mechanical industry in past decades, the act of bolting has remained the same even though types of machinery and their structures have continued to grow more complex.
Irrespective of the size and nature of the machine or equipment maintained into position by a bolt and nut or a bolt and stud, an incorrect tightening can result in maintenance problems, ductile rapture, machine failure and injuries to workers.
Hydraulic Torque Wrenches from PowerTeam, are specially designed equipment for efficient tightening and loosening of bolts in industries through the use of hydraulics. By application, torque wrenches exert the predetermined, controlled amount of torque to a hydraulic torque head.
Hydraulic torque wrenches are widely used to produce thousands of Newton Meters of repeatable torquing force in the fields of construction, machine assembly, and maintenance. They are very capable of tightening and loosening very large bolts within a confined area or unsafe, fragile locations. They are as well efficient in breaking loose heavily corroded bolts for disassembling machines.
Definitive and critical machine processes and functions depend on bolts tightened within the bolt’s material specifications, the material being joined and the operational activities to be performed. Should a bolt be loosely tightened, member parts of a machine may be forced to fall apart or pipeline flange gaskets may be caused to leak by vibrations. In the same vain when a bolt is tightened too much, the stress can cause the bolt to break.
Bolt tightening operation is never an easy task. It requires particular attention to be paid to the choice of tightening tool, the process, and the control method. Tightening loads must not be too low or too high, but must be evenly distributed among the bolts. Any defect in these three can impact badly on the performance of the assembly and can lead to shorter life-span. When the necessary precautions for tightening are not well taken, the real tightening preload on all the bolts will not fit well with the requirements and would be badly distributed.
PowerTeam Solutions for Preventing Bolt Over-tightening
Low Clearance Hydraulic Torque Wrench – TWLC
PowerTeam Low Clearance Hydraulic Torque Wrench (TWLC) is uniquely designed for bolting in precarious areas. The TWLC is a highly versatile tool that can prevent time wasting in bolting operations. This is because; it has interchangeable links that can be changed easily and without the use of any tools.
TWLC have swivel manifold internal relief valve that impedes retract side over-pressurization. Also, the compact frame size and small nose radius of TWLC makes bolting in precarious areas very easy.
Square Drive Hydraulic Torque Wrench – TWSD
PowerTeam Square Drive Hydraulic Torque Wrench (TWSD) is a very powerful hydraulic bolting device that has several features such as, floating piston, multi-axis high flow swivel manifold and a 360 degrees push lock reaction arm. These features makes the TWSD a very efficient bolting tool that is capable of preventing over-tightening that can cause damage to machines.Report this
