A Pin Retainer Plate is a flat plate used to prevent the pin from coming out or getting lost during the operation, ensuring that it remains securely in its intended position in the grapple housing. The plate is welded with the housing to prevent the pin from sliding through the hole as it is subjected to vibrations, shocks, or other forces that could cause it to come loose or fall out.

Attributes:
• Provides reliable retention for the pin
• Provided with high strength and wear resistance

Applications:
A Pin Retainer Plate is used to hold and secure the pin that connects the male and female grapple tongs to the grapple housing, ensuring the proper position of the pin.
