Four electric motors power eight winches per caisson via speed-reduction gearboxes and the 73.15-metre (240.0 ft) lift is completed in seven minutes. The structure is massively reinforced to provide rigidity against torsional forces during operation and has a mass of approximately 200,000 tonnes. [ 1 ]
The Anderton Boat Lift is a two-caisson lift lock near the ... Saner proposed electric motors and a system of counterweights and overhead pulleys that would allow the ...
A boat lift, ship lift, or lift lock is a machine for transporting boats between water at two different elevations, and is an alternative to the canal lock. It may be vertically moving, like the Anderton boat lift in England , rotational, like the Falkirk Wheel in Scotland , or operate on an inclined plane , like the Ronquières inclined plane ...
The security of the lift is maintained by keeping half the cables in tension and the other half relaxed in reserve. The guide rollers have a diameter of 3.5m. Pin gearing with D.C.motors in Leonards electric motor speed controllers, connected together by a shaft allow a symmetrical drive. This arrangement allows the exact synchronisation of the ...
The pivoting design allows the outboard motor to be swiveled by the operator in almost all directions: Sideways for direction, up and down to change the thrust line according to speed or bow lift, elevate completely out of water for easy starting, placing the drive shaft and the propeller forward along the side of the boat for reverse, or put ...
By 1900, electric-powered pleasure boats outnumbered [citation needed] the combined number of boats powered by steam and explosive engines (as gasoline-powered motors were called). [citation needed] By 1910, the advantages of the range and power of gasoline came to dominate the market and Elco converted to motor boats. [5]
