Hydraulic Extractor


Hydraulic Extractor

Heavy Duty Hydraulic Extractor for extremely seized ERC's (30 Ton) is manufactured using cutting edge technology. The Hydraulic Extractors manufactured by our company ensures excellent quality and high end performance. High reliability and outstanding performance of Hydraulic Extractor offered by our company has increased their demand in the market.

Functions
  • The machine is designed to free/loosen only extremely seized/jammed pandrol/elastic rail clip in one setting from the insert of PSC sleeper by a straight, aligned force of 30000kg developed by high pressure hydraulic pump and cylinder combination, without infringing rail traffic and damage to sleeper
  • Eliminates-The twisting force on the insert which develops cracking force at the insert of the sleeper
  • Improved design does not requires extra fastening J-hooks, time consuming fastening of J-hooks, expertise to set correct anchoring force and clearing of blast on other side of the rail to make space for J-hooks
  • The use of conventional hammering and heating method generally used for the extraction of seized elastic rail clip/ pandrol which causes irreversible damage to the sleeper, is not required any more
  • Saves the requirement of replacement of damaged sleepers due to broken and seized ERC’s
  • The effort required to develop 30000ky extraction force is about 35 kg
  • The equipment exerts a co-axial force of 30tons (Max) to the jammed stem of the elastic rail clip
  • An extraction stroke of 40mm (Max.)
  • The equipment weighs approx.29 kg and can be handled, fitted and operated by two workmen
  • Provides a over load valve preset at 25000 kg force
  • A thrust pin fits at ram end between a guide arrangement to prevent fly out of pin on load
  • A ram retraction spring automatically withdraws the ram on release of pressure
