Arch Engineers Ltd. collaborated with Henry Drilling to develop a critical Two Crane Tandem lift plan for the removal and installation of a 32-foot-long, 63-tonne pile oscillator. This high-risk operation required detailed planning, particularly in calculating the center of gravity and developing a precise rigging configuration to ensure safe execution.
The lift involved two cranes operating in tandem, each using high-grade rigging rated for up to 35 tonnes per pick point. Arch Engineers carefully optimized the lifting radius and load distribution, ensuring both cranes stayed within their operational capacity limits throughout all phases of the lift.
Another key aspect of the plan was coordinating the oscillator’s final resting position. The engineering team mapped out exact crane movements and swing paths to ensure seamless placement with minimal adjustments. This coordination minimized ground crew intervention, improving safety and efficiency.
One of the primary challenges was limited rigging availability. The team overcame this by designing a solution that maximized the use of available gear while maintaining all required safety margins. Despite the constraints, the Two Crane Tandem approach allowed for full control of the oscillator throughout the operation.
Arch Engineers’ lift plan ensured a smooth and secure process from start to finish, avoiding delays and eliminating unnecessary risk. The successful completion of this lift reflects Arch Engineers Ltd.’s expertise in developing innovative, field-ready solutions for complex heavy-lift operations. It also underscores their ability to adapt quickly under tight logistical and technical constraints.
