Project Overview
PSC Crane & Rigging was tasked with supporting the installation and relocation of a 180,000 lb press frame and associated automation components at the American Rheinmetall facility (formerly Loc Performance).
Scope of Work
Unloading and staging of press small parts and automation line components. A smaller mobile hydraulic crane was mobilized in the front parking lot to perform the initial unloading and placement of the press frame onto PSC’s self-propelled modular transporter (SPMT) trailer. The press frame and trailer were temporarily staged on site for up to two weeks while awaiting mobilization of the heavy lift crane. A 550-ton mobile hydraulic crane was then set up behind the facility to support final placement operations. PSC transported the press frame around the building using the SPMT to access the lift area. The frame was rigged, stood up, and lowered through the roof into the press pit. PSC completed final positioning by shimming, leveling, aligning, and anchoring the press per customer specifications. The team also supported OEM representatives with the installation of press small parts and automation equipment.
Challenges and Solutions
Challenges:
- Scheduling: Coordinating unloading services around delays from overseas barge transport, freight forwarding, and heavy haul trucking.
- Access: The over-the-road transporter could not reach the building’s rear for roof access.
- Weather: The press frame installation required a roof opening, which was impacted by wind and rain conditions.
Solutions:
- Scheduling: PSC deployed a smaller mobile crane for initial unloading and used onsite storage on the SPMT trailer to provide flexibility in coordinating the heavy lift crane and roofing crew.
- Access: Utilized a 6-line Goldhofer SPMT to maneuver the press frame around the building to the roof entry point.
- Weather: Maintained daily coordination with weather forecasts to ensure a safe and efficient lift window.
Equipment Utilized:
- 240 Ton All-Terrain Mobile Hydraulic Crane (Initial Unloading)
