Manual twistlocks<br />
CV-8, CV-8G<br />
Manual twistlock<br />
The MacGregor CV-8 and CV-8G bottom<br />
twistlocks are designed to handle the large<br />
forces and wear that occur at the bottom<br />
of a container stack. In accordance with<br />
Germanischer Lloyd’s rules for higher pressure<br />
forces, the CV-8G bottom twistlock housing is<br />
designed with a larger wear surface.<br />
Bottom twistlocks are used on the bottom<br />
corners of containers sitting on hatch covers,<br />
pedestals and deck extensions. At sea, these<br />
twistlocks incur longitudinal forces caused by<br />
torsional deformations of the ship’s hull. These<br />
longitudinal forces have to be addressed by<br />
either incorporating sliding foundations or<br />
by using ISO standard twistlock foundations,<br />
which have an elongated ISO hole.<br />
When torsional deformation occurs the<br />
containers will slide on the pedestals, causing<br />
wear to the base of the twistlocks. When the<br />
forces and the torsional deformation are large<br />
the wear can be excessive. In worst case<br />
scenarios, the forces and wear can cause<br />
cracking and finally failure of the bottom<br />
twistlocks during a voyage.<br />
MacGregor CV-8 and CV-8G bottom twistlocks<br />
fulfil all safety criteria and out-perform others<br />
in this tough environment.<br />
The CV-8 series of bottom twistlocks are<br />
designed for active duty and are easy to<br />
operate with a manual locking handle. To best<br />
match your vessel’s needs, the CV-8 series<br />
of manual twistlock are available in three<br />
different models: the standard CV-8; the CV-8G<br />
with an enlarged wear surface; and the CV-8B<br />
with an extra large wear surface and built-in<br />
wear indicator.<br />
Both the CV-8 and CV-8G units have left-hand<br />
locking mechanisms.<br />
