Girder Clamps
Lindapter clamping systems provide a fast, cost-effective alternative to on-site drilling or
welding by helping to reduce installation time and labour costs. High strength, permanent
(or temporary) connections are achieved by simply clamping two steel sections together.
Quick and easy to install
1) Bring the location plate and lower beam into position below the upper beam.
2) Fit bolts with two Lindapter clamps, any packings required, a nut and a washer.
3) Using a torque wrench, simply tighten each bolt to the recommended torque.
1)
2)
Standard: Beam-to-beam (tensile loading)
The original configuration is designed to secure steel sections and resist tensile
loading. It features a pre-drilled location plate that is placed between the beams to
locate the four bolts. Each bolt has two Lindapter components to clamp the flange
immediately above and below the plate. For thick beams, a packing piece is required
to raise the height of the clamps to enable the product to sit correctly on the beam.
High Slip: Beam-to-column (slip resistance)
This configuration utilises a High Slip Resistance (HSR) clamp per bolt
to achieve a secure connection to vertical columns. An end plate is
pre-fabricated to the section that will be joined to the column. The
purpose of this plate is to locate the bolts and provide a fastening
position for the Lindapter clamps.
Adjustable: Inclined beam-to-beam (combined loading)
A fabricated assembly, optimised with Lindapter’s adjustable HSR clamps to
resist both tensile loading and slip. This solution adjusts to fit a wide range of
flange thicknesses for added convenience. Lindapter can design and supply
the entire assembly to suit individual applications.

Hollo-Bolt
®
The original expansion bolt for structural steel requires access from one side only to quickly
connect steel sections to pre-drilled Structural Hollow Section (SHS). Hollo-Bolts are a faster
alternative to welding or through-bolting, reducing construction time and labour costs.
Quick and easy to install
1) Align pre-drilled fixture and section then insert the Hollo-Bolt.
2) Grip the Hollo-Bolt collar with an open ended spanner.
3) Using a calibrated torque wrench, tighten central bolt to recommended torque.

Standard Hollo-Bolt (M8-M12)
Hollo-Bolt HCF (M16-M20)
A typical connection is made by inserting the HolloBolt into the pre-drilled holes of the fixture and hollow
section. As the bolt head is tightened, the cone is
pulled up the bolt thread, causing the sleeve to
expand until the cone locks the sleeve against the
hollow section’s inner wall.
Working closely with Structural Engineers and Steel
Fabricators, Lindapter identified the need for the
larger M16 and M20 Hollo-Bolts to have an increased
clamping force suitable for higher strength structural
connections. This led to Lindapter’s invention of the
High Clamping Force (HCF) design.
At full tightening torque, clamping force is established
between the fixture and the steel section to form a
secure connection. Once installed only the head and
collar are visible.
The Hollo-Bolt HCF features a patented mechanism
that allows the product to produce a typical clamping
force over three times higher than the same sized
product without the mechanism.

Other Lindapter products
Since 1934, Lindapter has continuously developed its product range to include connection solutions for almost
any steel-to-steel application. In addition to its flagship Hollo-Bolt and Girder Clamps, Lindapter specialises in
five other product groups which are detailed below.
Rail Fixings
Lifting Points
For securing rails or crane lines
in low speed applications such as
ground track, elevated rail and
overhead gantries. These fixings
are used in environments including
train maintenance depots, industrial
facilities, water treatment plants,
dam/dockside cranes, automated
warehouses and power stations.
Lindapter lifting points are used in
a variety of industries to support
the lifting and rigging of equipment.
Applications vary from suspending
overhead light duty audio-visual
kit in theatres to lifting
heavy drilling risers
onto offshore
platforms.
Lindapter
can design
bespoke lifting
points to your
specific
application
requirements.

to allow quick and precise rail alignment.
Floor Fixings
Innovative fixings for securing steel flooring
to the supporting steelwork without the
need for on-site drilling or welding.
Access to the underside is not
required, eliminating the need
for costly scaffolding or elevated
floors. Installation can be carried
out quickly and safely from above
by one person.

open bar grating from above, helping to
reduce costs.

Decking Fixings
High quality, cost effective connections for securing building services.
Designed to fit inside the dovetail re-entrant channels of popular
composite decking profiles, Lindapter’s fixings provide
a zero-impact method that avoids
delamination and damage
to the decking.
Pictured: The Type ALP selfadjusts to suit various beam
sizes and lift orientations.
Support Fixings
These easy-to-install connections
are designed to suspend building
services from structural or secondary
beams. Typical applications include
HVAC equipment support, pipe work,
fire protection and sprinkler systems.
Adjustable to allow a fast and precise
alignment of building services.
Pictured: Type F3 has a large clamping range
to suit a wide range of flange thicknesses.
Pictured: Type TR60 consists
of a wedge and locking plate
and is quick to install.
