Y-handle design stops accidental triggering

Edited by the Engineeringtalk editorial team Dec 18, 2006

A new Y-Handle design for LG Series Dzus Lockwell Quick Release Pins available from Southco, features a cupped recess to protect against accidental triggering of the pushbutton that releases the pin

The flared handle also provides a convenient grip for pin insertion or removal.

Because the protected pushbutton design provides an added safeguard without inhibiting ease of use, it is ideal for frequently accessed applications in high traffic areas or situations where accidental release could be particularly dangerous.

Vibration resistant performance also helps to maintain the positive grip of the pin in the installed position.

These pins are a quick, dependable alternative to nuts and bolts, cotter pins, or lynch pins for locating, positioning or retaining objects in a variety of applications - aerospace, marine rigging, transportation (trucks, off-highway, railway, towing, motor sports, etc)., medical or industrial equipment, lighting, and fitness equipment.

The single acting design of the pin allows for quick and convenient tool free insertion or removal with a simple press on the pushbutton.

Pressing the pushbutton allows the detent balls at the end of the pin to retract into the pin housing so that the pin may be inserted or removed from its mounting hole easily.

When that pushbutton is released, a spring loaded shaft within the pin forces the detent balls out, creating a positive locking action that retains the pin firmly in its mounted position.

Users can choose between a two ball design and the four ball design for increased tension load capability.

The new Y-Handle is the latest of seven handle designs in the broad range of LG Series quick release pins.

Like all pins in that series, it is available in diameters from 3/16 to 1in, and is manufactured to custom lengths in 0.001in increments.

Whether they are manufactured as commercial grade, or produced to aerospace/military standards, all pins are made to order, so they can be specified for the unique fit, strength, and performance requirements of the application.

Material options including stainless steel and 4130 alloy steel provide robust performance with a high strength-to-weight ratio for a wide range of application environments.

Tension load capability ranges from 200 to 7120lb, with shear strength ranging from 4600 to 147,000lb, depending on the size and construction material of the pins.

The new Y-Handle pins and all other LG Series pins can be equipped with a variety of accessories to satisfy additional needs.

Chain-style or cable-style lanyards keep pins safely tethered to prevent pin loss or damage to operating equipment caused by a dropped pin.

Mating receptacles are available to provide a positive locking point for blind hole applications or where the mating surface does not provide sufficient hardness for positive engagement of the detent balls.

And coloured streamers are available to flag critical applications.
