Product Details:

Destaco 578 vertical hold down clamp applies downward clamping force by increasing the applied load via toggle mechanisms. This model features a fixed design to secure & loosen workpieces without moving the clamp itself. This clamp offers a stationary alternative to removable C clamps or spring clamps when securing material to a work surface. It holds workpieces in place using a lever handle that is pushed to the upright position when the clamp is engaged. Destaco 578 vertical toggle clamp comprises accurately machined components that have hardened and ground pivot pins and bushes. It has an ergonomically designed handle to minimise strain and pain while working. The lever handle engages & releases the clamping head, which holds a workpiece onto a worktable. Destaco 578 vertical hold down toggle clamp offers the clamping ability to reduce necessary fixtures for a particular application. It can easily adapt to workpieces of different heights. This vertical hold down toggle clamp is virtually maintenance-free and only requires a few drops of lubricating oil to keep the unit in excellent condition. It enables the user to undertake an action without being worried by the frequent movement of a workpiece. This toggle clamp is equipped with a unique pivot and lever system that ensures excellent performance. Destaco 578 vertical hold down clamp provides high exerting force and flexible adjustability that are useful when working with materials of varying thicknesses.

Frequently Asked Questions:

Q. What is a vertical hold down clamp?

A. Destaco vertical hold down clamps are designed for holding the workpiece stationary against a flat surface / workbench for various industrial applications like woodworking & metalworking.

Q. What is the difference between a vertical & horizontal toggle clamp?

A. The difference lies in the positioning of the clamp handle when the clamp is in the locked position. A vertical clamp handle is positioned vertically (perpendicular to the base) when in locked position, while in the case of a horizontal toggle clamp, it is positioned horizontally (parallel to the base).

Q. What does holding capacity mean in terms of clamps?

A. The holding force or the holding capacity signifies the clamp's capability to hold down equipment or sheet metal on the assembly line or during manufacturing processes.

Q. Which grease is ideal for Destaco clamps for their rebuilding?

A. A coupling grease like Mobil XTC should be used when dealing with Destaco mechanical clamps, while the Magnalube G grease is great for use with pneumatic cylinder seals.

Q. What is the significance of the red colour of the handle of Destaco clamps?

A. There is no such significance of the colour of the clamp's handle, as it only represents a recognisable area. This helps operators in finding the handle quickly & easily.

Q. What variants of Destaco vertical handle toggle clamps are available on Raptor Supplies?

A. Destaco vertical handle toggle clamps are available in steel, stainless steel and forged alloy steel variants.

Q. How does a vertical hold down toggle clamp work?

A. The toggle clamp actuates against the workpiece and compresses or stretches the equipped linkages to keep the workpiece in a stationary position.

Q. How are toggle clamps measured?

A. Toggle clamps are available in multiple variants having different holding capacities. The capacity of a particular toggle clamp can be measured by calculating the distance between the clamping plate (at its highest position) & the workbench.

Q. What does clamping force mean?

A. Clamping force is the amount of force actually applied to the workpiece by closing & locking the clamp. It is normally less than the stated holding capacity. The actual clamping force depends on various factors, including cylinder bore, cylinder area, spindle position (clamping arm length) and available air pressure. In most cases, the clamping force is approximately 2 to 3 times the force exerted by a pneumatic cylinder.
