Bingley Five Rise Locks

Bingley Five-Rise Locks is a staircase lock on the Leeds and Liverpool Canal at Bingley . As the name implies, a boat passing through the lock is lifted or lowered in five stages.

In effect the five-rise consists of five locks connected without intermediate "ponds": the lower gate of each chamber forms the upper gate of the chamber below. There are therefore five chambers, and six gates. As the Leeds Liverpool canal is a wide canal, the chambers are slightly more than 14 feet wide, and each gate consists of two half-gates, "hinged" from opposite sides of the canal. Each half gate is slightly more than 7 feet wide, so that the two halves close in a "V" shape . Water pressure on the uphill side of the gate keeps it tightly closed until the water levels on either side are equal, when the gate can be opened and the boat moved to the next chamber .
