Load Pins

For almost 20 years Delphi have been producing high quality load pins to suit a variety of loading applications.


Measurement ranges of 100kg up to a massive 500t have been designed, machined, assembled and tested in our manufacturing facility on Queensland's Gold Coast.

Our load pins are well known within the crane, lifting and winch industries - thanks largely to the safety factor our designs - which typically exceeds 7:1 (minimum 6:1) to fall in line with rope safety factors in the lifting industry.

Many of our load pins are used to replace a pin in an existing machine or at the design/assembly phase of new equipment - often as part of a wedge socket, sheave or shackle.

Our custom build capability and short lead times are critical to our success.
