S-42XCR NPK S-42XCR Specifications & Technical Data (2008—2026)

More power - more production

The main cylinder is designed so whenever the jaws meet resistance, the hydraulic booster is automatically activated. The pressure intensifier system has a relatively low oil flow, which produces faster cycle times and more crushing strength when compared to competitive crushers without a booster system. Additionally, other excavator functions remain uninfluenced by this system. The integral booster reduces the total weight of the attachment, allowing for a compact body design and ease of maintenance.

Npk powerbooster compared with normal cylinder and differential cylinder

Calculations show that the cycle time of a NPK booster cylinder defeats crushers with a normal cylinder or differential cylinder. The job is finished earlier, and the profit is yours. Besides more production and more power, a shorter cycle time also results in less fuel consumption, with a reduction of 25-50% per cycle being realistic!

Features

Only NPK offers an exclusive integrated booster system that automatically activates when the jaws meet resistance.Low weight, long reach.Large jaw opening.Arm/Dipperstick mounted.Piston rod and hoses fully protected inside the crusher’s frame.Slim-line design.9 Models available to suit excavators from 2-55 tons.Fast opening/closing times from 2.1 sec’s in unloaded condition, producing 28 cycles a minute.Most models have 360° free hydraulic rotation. S-3XC, S-4XC, and S-7XC are standard with 360° mechanical rotation.Maintenance friendly.Reinforced steel cutters are standard (Except S-60XCR).Low oil flow ensures other functions of the excavator are not influenced.Excellent stability even for high-lift demolition.Reliable and efficient.No additional pressure reduction is required in the hydraulic system.

Long Reach Demolition

Used in long reach demolition, the crushers show their advantages even more. The slim design offers better visibility for the operator and reduces the chance of debris falling into or onto the crusher. Additionally, the NPK Booster system is unaffected by the back pressure in the return hoses. This is extremely important since back pressure in the long hoses can influence the correct functioning of the hydraulic system, causing loss of power and speed.
