Bingley Five Rise Locks

The Five Rise Locks from below

Bingley Five Rise Locks is a staircase lock on the Leeds and Liverpool Canal at Bingley (grid reference SE107399). As the name implies, a boat going up the lock is lifted in five stages.

Description

In effect the 5-rise consists of five locks connected together with (as always with a staircase) no intermediate "ponds": the lower gate of each chamber forms the upper gate of the chamber below. There are therefore five chambers, and six gates (the top and bottom gates and four intermediate gates). As the Leeds Liverpool canal is a wide canal, the chambers are 14 feet (4.3 m) 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 (2.1 m) wide, so that the two halves close in a "V" shape (pointing "upstream"). Water pressure on the "uphill" side of the gate thus 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 (see canal locks for more information on how a lock is constructed and operated).

The 5-rise is the steepest flight of locks in the UK, with a gradient of about 1:5 (a rise of 59 ft 2 in (18.03 m) over a distance of 320 ft). The intermediate and bottom gates are the tallest in the country. Because of the complications of working a staircase lock, and because so many boaters (both first-time hirers and new owners) are inexperienced, a full-time lock keeper is employed, and the locks are padlocked "out of hours". Barry Whitelock, the lock keeper, after twenty years based here is now almost synonymous with the flight. Barry was awarded an MBE (Member of the Order of the British Empire) in the 2006 New Year Honours List for "Services to Inland Waterways in the North". The Locks also have an overflow waterfall at the side, which water runs down when the lock is not open. Also, when the oard enters the lock, it opens another overflow at the side of each pond and they run into the main overflow.^[1] The structure is Grade I listed.^[2]

History

It opened on 12 March 1774 and was a major feat of engineering at the time. When the locks and therefore the canal from Gargrave to Leeds was opened in 1774 a crowd of 30,000 people turned out to celebrate. The first boat to use the locks took just 28 minutes and the whole first trip is described here ^[3] as it was in a newspaper of the time - the Leeds Intelligencer. The smaller Three Rise opened at the same time just a few hundred metres further down.

Tourism

The staircase is a major tourist attraction in the area. Most boats that pass through attract a lot of attention especially at weekends where there may be a crowd of thirty people or more watching a boat go up or down.

Maintenance

The staircase underwent extensive restorative maintenance in 2004, and again in 2006 when the lock gates and paddles were replaced. As is expected with such a feat of engineering it requires a lot of maintenance and is often on British Waterways' list of winter stoppages for maintenance.

In January 2012, the locks were drained to allow the installation of new lock gates. The new gates are made of English green oak and, when installed with the balance beam, weigh over 5 tons.^[4]
