Hydraulic bolt tensioner

Technofast Industries has updated its EziJac B3S series of hydraulic bolt tensioners to make them more efficient, longer lasting, user friendly and safer.

The B3S Series EziJac is a modular style hydraulic bolt tensioner featuring a spring return mechanism which automatically resets the tool to its full working stroke. The modular design allows multiple adaptor kits to be interchanged with just the one load cell.

Suitable for whenever accurate and repeatable loading is required across a wide range of industries, the new updated model includes a number of important features all designed to reduce maintenance costs and improve productivity.

One of the key features of the upgraded B3S Series EziJac hydraulic bolt tensioner is an innovative new 2-piece seal design which offers even faster operation of the tensioner due to lower friction.

Technofast’s Founder and CEO Mr John Bucknell says the new seal also improves the longevity of the bolt tensioners, which are now capable of well over 1000 cycles before seal replacement is required.

“We have also designed new improved seal retainers, to further enhance the reliability of the bolt tensioners.

“Customers will be very impressed with the longevity of this new model, which was already outstanding,” Mr Bucknell said.

As well as the new seal design, the return force of the return springs of the bolt tensioner has been increased to further improve efficiency and speed of operation.

Offering very accurate bolt tensioning, the B3S Series EziJacs also feature a new puller design making them far easier to be operated by workers wearing gloves.

The EziJac bolt tensioners offer reduced assembly time for critical jointing applications and where simultaneous tensioning of bolts is required, such as flanges where even gasket compression is required.

As well as being ideal for confined and difficult nut locations, the B3S EziJacs require little physical effort to operate and are ideal where rotational or torsional stresses are a problem, and where regular maintenance requires repeated adjustments or removal of nuts.

Suitable for a wide range of applications, including the mining, oil & gas, power and manufacturing industries, the EziJac hydraulic bolt tensioners offer reliable and precise tensioning, coupled with improved safety on the job by eliminating hammer tightening and pinch points, and with remote pumping, no operators are in close proximity to the work area.
