Nonmarring Vertical-Lift with 180° Flip Plate Clamps

Pads on these clamps prevent the grip from biting into the load. They can take a metal plate of any hardness that is stacked horizontally, lift it vertically, and then place it down horizontally on its other side. Clamps close under their own weight; as the load increases, so does the grip. The lock keeps them closed to prevent accidental release. Clamps automatically open and lock when they are not under load so a new plate can be easily inserted. They have an eye that pivots to allow lifting angles up to 15° without reducing the capacity. The eye adjusts to accommodate unbalanced loads.

Warning: Never use to lift people or items over people.

Swivel-Tip Set-Screw Grippers

Grip angled and uneven surfaces with precision and ease. These grippers thread into either side of your fixture or plate. You can even position them so their serrations are flush with the surface. Adjust their height with a hex key. For a secure hold, clamp your workpiece against them.

Ultra-Fine Serrations—Ultra-fine serrations are the most closely spaced for the lightest penetration of the workpiece.

Vertical-Lift with 90° Tilt Plate Clamps


Automatic Close	Automatic Close with Lock

Clamps can take a metal plate that is stacked horizontally and tilt it up 90° so it can be lifted in a vertical position. After lifting, clamps can place the plate back down in the original position (plate can not be flipped over).

Warning: Never use to lift people or items over people.

Automatic Close and Manual Open—Automatic close clamps close under their own weight; as the load increases, so does the grip.

Automatic Close with Lock—Automatic close clamps close under their own weight; as the load increases, so does the grip. Clamps with a lock stay closed to prevent accidental release.

Manual Open with Lock and Remote Release—Manual open with lock and remote release clamps have a pull chain so they can open remotely when they are not under load. They lock when open for easy loading.

Vertical-Lift with 180° Flip Plate Clamps


A	B	C	D

E	F	G	H

J

Take the strain out of manually standing up stacked plates before lifting them—these clamps have a full 180° range of motion. They can raise the plate from stacked to standing, then lift it vertically, so you can move the plate where you need it. When you're ready to put the plate down again, they can place it on its opposite side.

To make sure the grip is secure for safe lifting, only use these clamps within their weight capacity range.

Warning: Never use to lift people or items over people.

Automatic Close and Manual Open—Automatic close and manual open are quick and easy to use because they don’t have a locking mechanism, but they are less secure than clamps with a lock. These clamps close under their own weight—as the load increases, so does the grip. To open, first set your plate down. Then, press down on the shackle until the cam retracts and remove the plate.

Automatic Close with Lock and Automatic Open with Lock—Automatic close with lock and automatic open with lock are more secure than clamps without a lock. They close under their own weight—as the load increases, so does the grip. These clamps must be unlocked before they will automatically open and release the plate.

Manual Close and Manual Open—Manual close and manual open use a screw to grip the plate, so you can fit a range of plate thicknesses. As the load gets heavier, the bite of the cam increases, which gives the clamp a secure grip on the plate. To open, first set your plate down. Then, press down on the shackle until the cam retracts and remove the plate.

Style A—Style A have wear indicator grooves that let you know when the cam should be replaced—if any teeth are flattened, chipped, or dulled between the grooves, it’s time to swap it out.

Style B—Style B can lift I-beams.

Style C—Style C come with a two-leg sling to lift large or flexible plates.

45° Pivot and 90° Pivot—Pivoting clamps safely lift vertical loads at an angle. Also known as sideloading clamps, they are more flexible than rigid clamps. Use them individually or in pairs with a two-leg sling (not included) to lift longer plates.

Rigid—Rigid clamps lift vertical plates straight up and down but lose their grip when angled. Make sure your plate is fully vertical, and the bottom edge is resting on the ground, before lifting.
