Body : The body is made from tested  M.S. Plates. It is fabricated  with horizontal and vertical ribs for strengths and sturdiness, the body is annealed & stress relieved by  heat treatment  process to reduce the  chance of the body getting  cracked.

Swinging Lever : The  swinging   lever (pitman) is fabricated  out of M.S. Plates with high tensile strength and it is annealed by heat  treatment process and then it is precision machined  for smooth crushing stroke.

Toggle Plates & toggle Bearings : For equal balance and load distribution the crank shaft is centrally  fitted on  cast steel toggle  bearings. The cast steel toggle bearings withstand  excessive wear and tear and convey  correct crushing stroke.

Jaw plates & side plates :  The Jaw plates  are made  of high tensile manganese steel. One jaw is fixed  and the other Jaw is  fitted on swinging lever. The side plates  are of close fitting type which  prevent  any wear to the body , which is made out of high grade manganese steel.

Crank shaft & Bearing : The crank shaft is made of  forged steel and fitted in heavy duty spherical  double roller bearings  which ensures smooth operation. The bearings  are fitted on both sides of the crank shaft  and two in swinging lever, which are well  sealed against  possible entry of dust and moisture by labyrinth seals. For lubrication  grease  nipples are fitted at appropriate places.

Fly Wheels  : Heavy duty cast iron  flywheels  are fitted on both the ends  of crank shaft. These flywheels are machined all over, counter  weight fitted  and balanced  to ensure steady  crushing  force.

Warranty  : MARSMAN Jaw crushers are warranted for ONE YEAR against  manufacturing  defects. However, the warranty  does not cover breakdowns under normal wear & tear or due  to misuse made by operator.
