Service Provided: Crane Support & Heavy Lift Execution

Thackray Crane was selected to provide critical crane support for the installation of the Pherris Wheel at the Philadelphia Zoo, a landmark attraction in West Philadelphia’s Centennial District. This project required meticulous planning, precise coordination, and expert execution to safely lift and place the wheel structure within a constrained urban worksite.

Project Overview

The installation of the Pherris Wheel presented a unique challenge: erecting a large, rotational attraction in a vibrant public environment with limited staging space and strict safety parameters. Thackray Crane’s team collaborated closely with the zoo, general contractor, and onsite stakeholders to develop a custom heavy-lift strategy that prioritized efficiency, safety, and minimal disturbance to zoo operations.

Challenges

• Tight Work Area: The footprint around the installation zone was restricted by zoo pathways, existing exhibits, and public visitor routes.
• Precision Placement: The wheel components required exact alignment during lift and set-down to ensure structural integrity and operational function.
• Public Safety Considerations: With the zoo remaining open during installation, managing public access and maintaining clear safety zones was essential.

Our Solution

Thackray Crane’s project team brought a comprehensive plan to life using industry-leading equipment and proven lift techniques:

• Conducted thorough site assessments and coordinated logistics with all parties before mobilization.
• Positioned and operated cranes with certified rigging crews to lift, rotate, and set the wheel assemblies into final position.
• Maintained rigorous safety protocols, traffic control, and communication channels throughout the process to protect workers and zoo visitors alike.

Outcome

The Pherris Wheel installation was completed on schedule with zero safety incidents. Thackray Crane delivered a seamless lift experience that met technical requirements and supported the zoo’s commitment to enhancing its visitor attractions. The project stands as a testament to strategic planning and heavy lift expertise in a challenging, high-profile environment.
