The two guys in left front probably holding onto the ends of a surveyors "chain" (200 foot steel tape) for measuring things. The man on the left probably has the tape winding device in his hand.

An engineering chain was usually 100 feet long; engineering stations were 100' apart. I have worked with steel tapes that were 100 and 300 feet long.

Land surveyors used a chain that was 66 foot long. This was also called a "Gunter Chain" for the Englishman who developed it. 80 chains = 5280 feet - 1 mile. An acre is ten square chains [1 chain x 10 chains, or 2 chains by 5 chains = 43,560 sq feet].
