Hercules

Shock Absorbers – Pile Run Mitigation

Safelink’s line of Hercules shock absorbers has been developed with groundbreaking valve technology that sets a new standard for safety and efficiency in monopile hammering. The series combines high performance with a compact design and low weight, delivering a solution that is both user-friendly and cost-effective. These shock absorbers can be used continuously without downtime for charging or fluid refilling – ensuring maximum operational uptime on the project.

Why use a Hercules shock absorber in monopile hammering?

Monopile hammering exposes both the crane and hammer to extreme loads. Each blow generates powerful dynamic peaks that over time can damage the equipment – or in the worst case lead to total failure. A Hercules shock absorber acts as a buffer that absorbs and evens out these forces, providing safer, faster, and more cost-efficient operations.

Equipment protection

Without a shock absorber, the immense forces from the hammer are transferred directly to the crane and lifting equipment. This can cause:

  • Cracks or fatigue in the crane structure
  • Damage to wires, shackles, and lifting systems
  • Risk of failure in the hammer itself

A Hercules shock absorber significantly reduces these loads, extending equipment lifetime and preventing unforeseen downtime.

Safety during pile run

The most critical phase in piling is the pile run – when the pile suddenly loses resistance and the hammer drops faster than expected. This can create extreme force peaks that are both dangerous to crew and highly damaging to equipment.

A Hercules shock absorber mitigates these peaks, protecting both crane and hammer from harmful shocks while reducing the risk of deck accidents.

Increased efficiency

When the force peaks are absorbed by the shock absorber, the hammer can be used more aggressively without compromising safety. The result is:

  • Faster monopile driving
  • Shorter cycle time
  • Higher productivity across the entire project

Unmatched shock absorption performance

Thanks to advanced valve technology, Safelink’s shock absorbers achieve far higher efficiency than conventional models. This reduces the required stroke length and improves overall hammering performance.

No manual adjustments

Unlike conventional shock absorbers, Safelink’s design requires no manual adjustment of gas pressure or valve settings. This streamlines operations and reduces the risk of errors or downtime.

User-friendly touchpad interface

Setup, maintenance, and data access have never been easier. With a modern touchpad interface, the operator receives clear feedback, system status, and checklists – without manual paperwork.

Built-in piston rod locking

For operations with limited lifting height, piston rod locking is delivered as a standard feature. This allows the stroke to remain fully retracted during critical steps of the operation – ensuring safer and more efficient lifts.

In short: Safelink Hercules Shock Absorbers are built for maximum safety, high efficiency, and safer hammering performance.
