Efficient & Safe Lubrication of new Slipway Winch Wire Ropes
CUSTOMER PROFILE: CORY RIVERSIDE ENERGY
In August 2020 Cory announced the completion of works to rebuild and upgrade two WWII-era slipways at Denton Wharf on the banks of the River Thames in Gravesend, Kent, UK. The significant investment in the slipways was the first stage of the redevelopment of the site, since Cory acquired it in 2018. Each of the two slipways is capable of receiving ships up to a weight of 400 tonnes, a length of 60 metres and up to a width of 18 metres depending on the type of vessel.
APPLICATION
Slipway and downhaul winches
North Sea Winches designed, manufactured, and installed three new winches to replace
the ones previously in place. These included a 20- tonne main slipway winch and a pair of five tonne downhaul winches with accompanying pulley and guide wire ropes. (23mm & 34mm wire ropes) There is a also a larger 76mm wire rope that Cory is hoping to lubricate in future with a Viper Maxi Wire Rope Lubricator (the Maxi lubricates wire ropes with diameters of 50mm to 165mm)
