Combination Chain Tensioning Boom and Tensioning Sensor

A chain tensioning boom comprising:

• a chain tensioning boom having a first pivoting joint connected to a chain linkage assembly that connects to a first chain segment that can be tensioned against a second chain segment;
• said chain tensioning boom further comprising a second pivoting joint connected to a proximal end of a chain tension sensing unit that has a distal end with a tension plunger;
• said tension plunger having a connection to the second chain segment;
• said tension plunger having a sliding engagement inside the chain tension sensing unit;
• a compressible member attached to the tension plunger inside the chain tension sensing unit so as to urge the tension plunger toward the proximal end of the chain tension sensing unit;
• an electronic sensor means inside the chain tension sensing unit functioning to send an output signal when an electromagnetic initiator on the tension plunger passes a threshold distance from the electronic sensor means;
• wherein closing the chain tensioning boom creates a desired load tension between the first chain segment and the second chain segment via the chain tensioning boom chain linkage assembly and the chain tension sensing unit;
• wherein upon a decrease of the desired load tension the compressible member moves the tension plunger toward the proximal end of the chain tension sensing unit, thereby initiating the output signal from the electronic sensor;
• and
• wherein said output signal is indicated on a remote display via a connection between the remote display and the electronic sensor.
