Body
The body is made from tested ms plates. It is fabricated with horizontal and vertical ribs for strength and sturdiness and 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 ms 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 & 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.
Lubrication
All roller bearings are arranged for proper grease lubrication. The grease nipples are fitted at appropriate places. Drive the crushers may be driven by electrical motor or diesel engine. The power is transmitted directly from the prime mover by v-belts upon one of the wheels to give drive to the crusher.
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.
Flywheels
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 guaranteed for one year against manufacturing defects. However, the guarantee does not cover breakdowns under normal wear & tear or due to misuse / mistake made by operator.
