New HM-Series HydraMax topside bolt
tensioners from Enerpac are engineered
to provide powerful, swift and even
performance over multiple-bolt joints involved in
assembly and maintenance tasks.
The HM hydraulic tensioners – which complement
Enerpac’s proven GT topside tensioners – are
designed to overcome the dimensional constraints
and bolt load requirements of compact flanges
found in industries such as oil and gas, mining and
energy, manufacturing and process engineering,
liquids reticulation and bulk materials handling.
Generating 30% more load capacity than
traditional tensioners and available in maximum
capacities from 134-4,650 kN, HydraMax topside
tensioners fit all standard flanges, including ANSI,
API and Norsok L005 compact flanges.
“The tensioners’ compact size and high bolt
load capacity allow a maximum number of bolt
diameters to be covered with a minimum number
of tools, while achieving even bolting tensions
essential to structural integrity and safety,” says
Enerpac regional bolting leader, Andrew Marsh.
“HydraMax bolt tensioners are field-proven tools.
HydraMax tensioners have been the most recognisable
tensioner in Hydratight’s bolting portfolio
for more than a decade and are now becoming
an important element of the Enerpac range of
controlled bolting solutions as Hydratight and
Enerpac are merged to become a single company.
“This integrated range expansion will have
major benefits for bolting customers, including
the comprehensive national sales and service
backup for which Enerpac is widely respected
– as well as access from the one convenient
source, to the extensive Enerpac range of
professional bolting technology, all with global
standards of reliability, safety compliance and
traceability,” says Mr Marsh.
Features of the HydraMax HM-Series include:
• Fifteen load cells cover bolts from ¾” to 4”
and M20 to M100 – covering all standard
sizes with multiple load cell options
• Quick release bridge – faster turnaround for
different applications
• Long stroke capability of 9/16" (15mm) –
reduces number of actuations
• Twin ports – enables user to link multiple
tools
• Stroke indicator – for operator awareness to
deter tool over-stroke
• Anti-slip grip – for more secure handling
• Captive socket – eliminates falling object risk
• HM06-HM15 equipped with spring return –
faster retraction reducing cycle times
In addition to launching the new HydraMax bolt
tensioners, Enerpac is also updating the GT-Series
Topside Bolt Tensioner range, to which a new
GT7 tensioner will be added. The seven GT load
cells and bridges will cover bolts from 5/8" to 4”
and M16 to M105. The GT range will also benefit
from a captive socket system that will prevent the
socket falling or being lost from the tool.
Features of the GT-Series include:
• Seven load cell and bridges from 5/8" to 4” or
from M16 to M105 – requiring less investment
to cover all standard bolt sizes
• Detachable and rotational bridge – simplifies tool
positioning
• Full bridge window – increased access to socket
• Piston stroke indicator – for operator awareness
to deter tool over-stroke
GT-Series universal bolt tensioners – in capacities
up to 3,958.4kN (404 ton) at 1500 bar – and
HM HydraMax topside tensioners are particularly
suitable where operators want to achieve known
and accurate bolt loads across multiple applications,
such as pipelines, flanges, base bolts and
turbines.
