Application used on Manhattan Bridge, USA

(pictured right)

Girder Clamps are used to connect reinforcing steel girders to the underside

of the bridge.

BRIDGE STRENGTHENING

Steel flooring can be secured to the supporting framework

from above with Lindapter’s floor connections and simple hand tools.

SECURING MAINTENANCE ACCESS / WALKWAYS

Contractors use Girder Clamps toconnect permanent steel support

frames and temporary propsduring construction or renovation.

SUPPORTS AND PROPS

Lindapter’s pipe supports can be used to secure electrical services

to the steel sections of the bridge, including inclined steel beams.

PIPING AND ELECTRICAL SUPPORTS

Typical Applications

2 Why Lindapter?Since 1934, Lindapter has pioneered the design and manufacture of steel-to-steel connections which eliminate on-site drilling and welding. Here are just a few examples of how Lindapter’s independently approved solutions save contractors’ time and money:

Key Lindapter product benefits

Tested and Proven

Product: Type AFApplication: Structural support connections on a refurbishment

ALEXANDER HAMILTON BRIDGE NEW YORK CITY, USA

Lindapter Engineers provided a bespoke connection design using Type AF clamps to secure temporary support systems for cantilevered roadways during the major refurbishment and widening of the bridge, which now accommodates eight lanes of traffic over the Harlem River.

The adjustability of the Type AF, as well as its high resistance to slip and tensile performance meant this was the contractors’ ideal solution.

Product: Grate-Fast® Stainless SteelApplication: Securing open grate flooring for maintenance access

Grate-Fast secured open bar grating platforms along the full length of the bridge so Engineers could change the accent lighting.

Using just standard hand tools to secure the grating quickly, contractors completed the project on time and on budget. Grate-Fast was chosen for its superior clamping force, durability and Lloyd’s Register Type Approval, which covers clamping force, vibration and shock resistance.

CLAMPING FORCE

* Sizes M16 and M20, known as the Hollo-Bolt (HCF), feature a High Clamping Force mechanism to produce three times more clamping force than the same sized product without the mechanism. Turn to pages 40 and 41 to see the significance of clamping force and the superior performance of this unique product.
