(1) Polish the crosshead pin to mirror surface.

(2) The crosshead must establish protection cover, to avoid the incaution harms and operates the personnel.

(3) The engine is a two-stroke , crosshead type , direct reversible , constant pressure turbocharger and scavenging air cooled common rail marine diesel engine according to licensor standard execution.

(4) Infinitely adjustable crosshead — The crosshead is vertically adjustable with infinite resolution.

(5) The piston rod should be fitted with the crosshead bore.

(6) The calculating formulae for the speed and the acceleration of the tie rod and the ringy gear crosshead are induced based on the kinetic model of the transmission mechanism.

(7) A kind of switch controller is designed aim at the complexity of the robot system. Then the cooperative control between mobile machine and crosshead is obtained to achieve seam tracking accurately.

(8) It is a relentless or irresistible action of the machine grips or crosshead.

(9) Shell Alexia 50 Oil is Shell ? ? s main cylinder oil for low ( slow ) speed crosshead engines.

(10) The new unit uses the pitman reserse mechanism instead of the crosshead slide reverse rack, adopts weight balancing instead of air balancing, and is provided with an improved guiding system.
