Fully aware of the difficulties associated with wind turbine blade tensioning, the new TorcUP WTB Series is a purpose designed range of hydraulic bolt tensioning tools to suit most wind turbine bolting applications. All WTB Tensioning tools have the capacity to achieve the specified proof load requirements as detailed in EN ISO 898-1:1999 and ASTM A490M for grade 10.9 Bolts. These feature packed tensioners have been designed with rapid tensioning in mind and offer a safe, reliable and consistent method to simultaneously tension many bolts.
Swivel movement ensures versatility
Due to the very limited space available in many
blade bolt compartments and to help where many tensioners are connected together every WTB tensioner has the option of a 360o swivel connection. This 360o swivel operation allows the hydraulic hoses to be positioned in the best possible position to allow open access to the tensioning tools.
The New WTF is a purpose designed range of hydraulic bolt tensioning tools designed to suit most wind turbine foundation
bolting applications. The WTF tensioning tools can be supplied to suit many different All Thread Bars and the more convention- ally ISO metric and Imperial Unified Thread forms. These feature packed tensioners have been designed with rapid tensioning in mind and offer a safe, reliable and consistent method to simul- taneously tension many Foundation bolts. The TorcUP WTF range of tensioning tools have been fully site evaluated in the wind energy industry.
25mm (1”) Ram stroke for ‘One Pull’ Tensioning
Due to the unusual length of foundation bolts and the methods used to anchor the bolts into the foundation structure, it is usual to experience relatively large amount of bolt extension during foundation bolt tensioning. For this reason it is very im- portant that the bolt tensioning tool used has plenty of piston/ ram stroke capacity. The WTF range of tensioners offer up to 25mm piston/ram stroke capability for “one Pull” uninterrupted tensioning. Shorter Stroke foundation tensioners are available from TorcUP to be used where bar protrusion is limited.
Wind Turbine Bolt Tensioning Electric Driven Pump Unit
The TorcUP WTP3 is a self contained electric driven high pressure hydraulic pump unit that can generate pressures of up to 1600 bar. The unit is a perfect match with the wind turbine range of bolt tension- ing tools from TorcUP. One of the major features of the WTP3 Pump unit is the ability to totally remote control the pump from the controller hand grip. The WTP3 unit is designed to work in adverse environ- mental conditions, to ensure its durability the unit is certified to IP-56.
