The monument consists of the remains of incline haulage gear, dating to the 19th century. The winding gear stands halfway up the side of the Sirhowy Valley, above Bedwellty Pits at the top of a disused tramroad, and on the lip of an old quarry. This winding wheel was used to lower quarried stone down the incline to Bedwellty pits yard. The site has recently been restored.
The monument is of national importance for its potential to enhance our knowledge of 18th and 19th century industrial and transportation practices. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structure itself may be expected to contain archaeological inform.
