The Hi-Force On-Site Bolting Services Division was set up to address and offer the ideal solution to these issues."
Managed from the Hi-Force UK Head Office, the On-Site Bolting Services Division can offer clients pre-start on-site surveys, full and comprehensive analysis of bolted joint needs and requirements, development of correct procedures, including all required bolted joint load calculations, on-site supervision, using ECITB qualified and trained Supervisors, on-site bolted joint integrity training courses, for the nominated contractors technicians, full flange management control, utilising the Hi-Force BOLTRIGHT PRO calculation software and of course high quality UK manufactured bolting tools.
Haas, "Analysis of rock bolting
to prevent shear movement in fractured ground," Minerals Engineering, vol.
The mechanical interaction mechanism among steel tube, bonding material, and bolt is drawn in Figure 3; for a specific segment taken from the bolting
system, it always keeps axial mechanical equilibrium, which means that the overall resultant force applied on the upper end equals that of the lower end.
System markets a line of square-drive hydraulic wrenches that allows the use of standard-impact wrench sockets instead of individual wrench heads for each hex size.
That has led a group of engineers to form the Bolting
Technology Council, based in New York City, "to sponsor research, to collect and exchange information, and to do whatever else is required to reduce the uncertainties of assembly results."
As a major, UK headquartered manufacturer, Hi-Force, with overseas regional offices in Holland, Italy, UAE, Saudi Arabia, Azerbaijan, Malaysia and South Africa, has over thirty years' experience in the design, manufacture, operation and use of manual, pneumatic and hydraulic bolting
When sized correctly, a hydraulic torque wrench can cut many hours from typical bolting
Although many are still installed manually, mines are coming to appreciate that fully mechanised rock bolting
gives reliable good quality, efficiency and greater safety.
At that time, a ground support program consisting of rock bolting
The safety, speed, and reliability of the bolting
system selected must of course be matched with cost effectiveness.

quality is not necessarily a safety risk where systematic rock bolting
