When it comes to heavy lifting, space or budgetary limitations may preclude using a crane. Fortunately, there are other options.
The Power Slide system is designed to be a safe and simple alternative for moving overweight and oversized loads. It consists of a flat-topped track and skid shoes powered by hydraulic push/pull cylinders.
The Power Slide system can be customized for a range of capacities, including:
- 200 ton –4-inch height, light-duty slide shoes
- 300 ton –5-inch height, 75-ton slide shoes
- 500 ton –6-inch height, 125-ton slide shoes
- 1,000+ ton –engineered and fabricated to specifications
How Power Slide Works
The system involves four basic steps:
- The load is jacked up on hydraulic cylinders.
- The slide track is inserted underneath the load.
- Slide shoes are inserted into the track under the load and held in place by safety load stops.
- Hydraulic cylinders are attached to the slide shoes, allowing the load to be pushed or pulled along the track.
You can see the system in action in the video below:
The system’s most notable feature is its novel flat-topped track, which makes Power Slide easier to set up, use and maintain compared to traditional jack-and-slide systems. Its hydraulics can also be switched from push to pull with a simple lever change.
Industrial Applications for Power Slide
The Power Slide system was designed by Engineered Rigging to move large components, such as turbines, generators, transformers, vessels and motors. It complies with a variety of industry standards, including:
- AISC Manual of Steel Construction, 9th Ed. and 13th Ed.
- ASCE 7-10, Minimum Design Loads for Buildings and Other Structures
- AWS D1.1, Structural Welding Code
- ASME NQA-1-2004, Subpart 2.15, Quality Assurance Requirements for Nuclear Facility Applications
- 29 CFR 1926, OSHA Construction Industry Regulations
