打桩保护

Sudden free fall of the piles during pile hammering due to layering in the soil, so called pile runs or pile drops, is an increasing concern in the industry. The snap loads following pile runs can be very high, exposing both personnel and equipment to high risk.

Operational Challenges

  • Sudden free fall of the piles during pile hammering due to layering in the soil, so called pile runs or pile drops, is an increasing concern in the industry.

  • The snap loads following pile runs can be very high, exposing both personnel and equipment to high risk.

Cranemaster Benefits

  • Protection of crane and rigging against snap loads during piling.

  • Expensive interruptions in the piling process can be avoided.

  • Special Cranemaster® shock absorbers developed in cooperation with key players in the industry.

  • For challenging applications,  Cranemaster® Advanced Splash Zone Tension Mode (CAST) will give unsurpassed performance in terms of low DAF and the ability to avoid slack slings even for large objects and high waves.

Pile run with and without Cranemaster®

The simulation shows an example for a pile hammer (weight in air 300 ton). The hammer falls a distance of 0,8 meter, and is then stopped by the crane wire.

Without Cranemaster® (to the right):
Snap load = 964 ton
Significant ringing effect in the crane and the pile hammer

With Cranemaster® (to the left):
Snap load = 513 ton
Ringing eliminated
