H – Series Light Duty Clamps H – 1323 – SF

A workpiece can be safely secured down with the help of Vertical Toggle Clamps, which are manual clamping tools with a toggle action. These clamps provide a rapid action manual release and can be mounted vertically to a fixture or workbench. With the help of vertical lifting clamps, which resemble jaws and hold steel plates firmly, lifting sheet metal vertically is made easy. The Nobles RIG-MATE Vertical Plate Clamp is intended to be used as a typical plate clamp for lifting and rotating steel plates, lifting steel pipes, and lifting steel structures like H and I beams. Like every other RIG-MATE product, the clamp is made of lightweight, robust materials.

Quick-action clamps called toggle clamps work by employing an over-center locking mechanism called a "toggle action." The clamping arm meets the center to hold the fixture or workpiece in a locked position, and the clamping handle moves a linkage to its center position using a set of levers and pivots. The main survey tool used in mining surveying is the total station. When drifts of an underground mine are driven, a total station is used to record the exact location of the tunnel's walls, ceilings (backs), and floors.

Certain varieties employ a trigger system that allows the jaws to be modified with a lever or trigger. As an alternative, some models offer a conventional screw to adjust the clamp. The workpiece is compressed and held securely in position by the clamp closing around it when the screw is spun. Depending on how the handle is oriented, toggle clamps can be categorized as vertical or horizontal. As implied by their name, vertical toggle clamps have a vertical handle, whereas horizontal toggle clamps have a horizontal handle. When the handle is engaged, both varieties will exert a clamping force.
