DESTACO 847-U-RC Pneumatic Replacement Toggle Clamp, 1000 lb Holding Capacity

Destaco 847-U-RC is a replacement hold down toggle clamp which acts as the pneumatic adaptation of Destaco 247-U manual vertical hold down toggle locking clamp. It includes over-focus switch activity linkage combined with a pneumatic cylinder to deliver a versatile device ideal for a broad range of applications. This completely independent clamp requires just a pressure source for user safety. This Destaco pneumatic toggle clamp is sensor ready for both round and T slot style sensors. It includes in-built flow restriction to eliminate the need for external flow controls. This clamp accompanies a sturdy clamping arm for keeping workpieces safely set up and handling loads up to 1000 lb. The clamping arm allows more extensive leeway to simple stacking, utilising a tough helical cam component operated via a double acting air cylinder. It has a large opening angle that guarantees simple part evacuation and can handle pressures up to 145 psig.

Frequently Asked Questions:

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

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

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 does the clamp's holding capacity signify?

A. The holding capacity or holding force represents the capability of a clamp for holding down mechanical equipment or sheet metal while assembling automotive parts or during similar manufacturing processes.

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 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.

Q. Does Destaco supply any water resistant clamp sensors?

A. Yes, Destaco also supplies inductive sensors designed in accordance with IP65 standards to ensure protection from powerful hydraulic jets, dust & heavy rain.

Q. How much pressure is a toggle clamp capable of?

A. Destaco hold down toggle clamps apply downward clamping force by increasing the applied load via toggle mechanisms. You can see the clamping force on the packaging itself, which is specified in Newton (N). Use this information with the size of the toggle clamp to work out the degree of pressure that the tool will have to exert on a piece of wood. The larger the piece of wood, the greater the pressure required.
