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
