The FIRE RESISTANT RUBBER SHEET shows common in service life than on the hydraulic ordinary jointing SHEET, and full hydraulic ordinary FIRE RESISTANT RUBBER SHEET to ensure the accuracy of the closed-loop control must be used with servo valves, and servo valve expensive, bring costs rise. Electric, hydraulic ordinary FIRE RESISTANT RUBBER SHEET is set for the hydraulic and electric driven in one of the new common jointing SHEET, it incorporates all the hydraulic ordinary FIRE RESISTANT RUBBER SHEET shows the performance and the energy saving advantages, this electric-the combination of hydraulic hybrid jointing SHEET has become a common plate technology development direction.
