 When lifting, they grip
the beam at three points. When properly balanced and safely
guided, the beam can be handled even if the clamp is slightly off
center lengthwise.
Good safety procedures providing control of the lifted beam must
be used. Beams should be gripped as near the center as possible.
Snubbing lines at each end must be used to control excessive
twisting or swinging, and to guide the beam to its proper place.
Each lifting situation may have specific safety demands which
should be used as required.
Beam clamps eliminate the need for slings, chokers, and spreader
bars. The weight of the beam clamp automatically opens its tongs,
which slide under the flanges of the beam. When the clamp is lifting,
its center plate and gripping tongs work against each other—the heavier the beam, the greater the clamping pressure.
Model “NS” clamps have a recessed base to accept studs welded
to a beam surface.
Clamp-Co Inc. Pipe Grabs and Beam Clamps have been in continuous production for over 20 years. Their time-tested design and cost-effective performance have been repeatedly proven in steel erection, bridge construction, oil field and pipeline projects and other on-site and in-plant material handling applications. At "Clamp-Co" lifting devices are our only business and we take great pride in the manufacture and utility of our products. All load bearing components are manufactured from high strength, abrasion resistant or fatigue-proof steel alloys and each clamp or grab is individually assembled on dedicated tooling and tested to assure fit and conformance to our performance specifications. In addition to the standard units offered in this catalogue we also build modified units for special applications and offer factory rebuilding and recertification services for all of our clamps. We will inspect, rebuild and recertify your worn or damaged "Clamp-Co", beam clamps on original factory tooling at a substantial savings over new replacement. |
