Scorpion Lift solution that rises above space constraints
“A lift solution that rises above space constraints.”
Often, a project requires the power of a crane, but the limited space pervasive to nuclear utilities makes using one costly and time-consuming preparations — if not completely impossible. To tackle this problem, PSC's engineers leveraged the law of physics and their knowledge to design an innovative solution: the patent-pending Scorpion System. The Scorpion's frame uses friction to support the crane on a single wall within a building or on an exterior structure to virtually eliminate the typical ground-level footprint required for a crane. A compressive load applied to both sides of the wall maintains positive engagement at all times.
The Scorpion System provides several advantages over traditional cranes: rapid assembly without time- consuming preparations, improved load handling efficiency, optimized load control and superior lift-to-weight ratios.
Time & Cost Savings
The Scorpion System shortens the project schedule and saves money by:
- Eliminating the need for a pre-installed crane base, counterweights and core-drilling
- Installing in a single work shift
- Requiring only minor surface preparation and no structural alterations to the wall or existing components
- Relocating quickly as a single unit
Patent-Pending Design
- Compact design requires wall length of less than 10 feet
- The frame extends vertically less than 4 feet from the top of the wall
- Independent downriggers accommodate variances in the wall thickness
- Custom modifications can be made to meet a nuclear plant's specific needs
Powerful Capacity
The Scorpion System can be custom-configured to meet a broad spectrum of loading, lifting and handling tasks.
- Maximum Overturning Moment of the crane with an FOS ≈2
- Maximum Moment: 4,000 pounds at 71 feet
- Maximum Winch Capacity: ~8,000 pounds (single-part line), ~16,000 pounds (two-part line)
Horizontal Load Capacity
Safe, Seamless Operation
Wireless controls provide the operator with increased mobility to safely control load handling. Its safety features include:
- 360-degree load handling capacity
- An automated synchronous control system
- Detached hydraulic power unit that provides convenient access to power controls
- Wall clamping force that is continuously monitored by load cells with a digital readout unit
