An easy press on the locking lever moves the jaw ahead approximately 3/32\", exerting the holding force, adjustable from 400 to 1100 lb. The recessed, parallel, steel jaw inserts level the work, and can be removed to accomodate jig and fixture components. The units have a hollow base for clear through drilling.

A press on the locking lever actuates the eccentric crank which tilts the locking ring, thereby gripping the entire circumference of the center bar, forcibly moving the jaw forward against the workpiece. Raising the locking lever to vertical position permits the spring to return the locking ring to neutral position, allowing the jaw to slide back, releasing the workpiece. Adjusting screw, locked by cover plate, controls amount of pressure.</span></td> <td><img src=\"https://cdn1.bigcommerce.com/n-yp39j5/4s9liwcv/product_images/uploaded_images/heinrich-sv-lock.png\" alt=\"\" width=\"202\" height=\"121\" /></td> </tr> </tbody> </table> <p>&nbsp;</p> <table> <tbody> <tr> <td style=\"padding: 10px;\"><span style=\"color: #000080;\"><strong><span style=\"font-size: medium;\">\"PA\" Series Locking Mechanism, w/ Pumping Action</span></strong></span><br /><br /> <span style=\"font-size: medium;\">Operator is able to advance the jaw forward by \"pumping\" the locking lever, thereby \"taking up\" on compressible materials such as warped castings, wood or metal laminations, plastics, etc. The addition of a holding ring holds the jaw against work with 200-350 pounds of pressure while the locking lever is at a 60-80 degree angle.

Heinrich Grip-Master GM Vises

Product Description

Heinrich Company

Heinrich Grip-Master GM Vises


Now a Standard in Industry Everywhere

A simple push or pull on the center bar sets the jaw in position. An easy press on the locking lever moves the jaw ahead approximately 3/32", exerting the holding force, adjustable from 400 to 1100 lb. The recessed, parallel, steel jaw inserts level the work, and can be removed to accomodate jig and fixture components. The units have a hollow base for clear through drilling. The bars and locking mechanism are hardened and ground.

Standard "SV" Series Locking Mechanism

For general vise and fixture use. A press on the locking lever actuates the eccentric crank which tilts the locking ring, thereby gripping the entire circumference of the center bar, forcibly moving the jaw forward against the workpiece. Raising the locking lever to vertical position permits the spring to return the locking ring to neutral position, allowing the jaw to slide back, releasing the workpiece. Adjusting screw, locked by cover plate, controls amount of pressure.

 

"PA" Series Locking Mechanism, w/ Pumping Action

Operator is able to advance the jaw forward by "pumping" the locking lever, thereby "taking up" on compressible materials such as warped castings, wood or metal laminations, plastics, etc. The addition of a holding ring holds the jaw against work with 200-350 pounds of pressure while the locking lever is at a 60-80 degree angle. The holding spring returns the holding ring to neutral position.
