Individual Soleplates
For light-duty applications requiring the installation of a sole plate for rail on concrete,
a discontinuous sole plate is a highly cost-effective solution. They can be secured with 2 or 4 holding-down bolts and
come complete with crane rail fixings, bolts, and grout. They can be purchased directly from
the source factory as heavy-duty crane rail sole plates (wholesale from a Chinese factory.
✔ Material usage is only 1/3 to 1/2 that of continuous systems, resulting in significant cost savings;
✔ Wheel pressure is transmitted through the base plate to the bolts and grout layer;
✔ Installation is simple, replacement is easy, and maintenance costs are low.
Continusous Soleplate
Heavier-duty crane rails or heavy-load applications require the strength of heavy-duty
continuous sole plate rail supports. Our continuous sole plates can be used with bolted or welded rail clamps. As a
leading manufacturer of crane rail sole plates in China, Glory Rail provides engineering-grade, custom-made
steel sole plates for continuous rail support.
✔ Welded base + epoxy grouting—the strongest solution for heavy-duty support;
✔ Continuous installation along the entire length—maximum flatness;
✔ Factory-pre-welded fixture bases—efficient on-site installation
What Are Steel Soleplates
Steel soleplates serve as the critical load-bearing interface between crane rails and concrete foundations. Classified by length, there are two mainstream types in the industry: long-type base plates (also known as continuous sole plates) and short-type base plates (also known as discontinuous sole plates or individual sole plates). Both serve as high-strength intermediate layers for precise leveling, secured with holding-down bolts, leveled using adjustment bolts, and grouted to fill gaps.
A complete crane rail fastening system typically consists of the following components:
steel sole plates → holding-down bolts → grout layer → steel sole
plates → holding-down bolts (welded or bolted) → rail shims → crane rails.
Each component is critical to long-term operational safety and precision.
Indivudual Sole Plates
A individual steel soleplates (discontinusous short-type base plate) is installed in sections at specific intervals (typically aligned with the bolt spacing) and is also commonly referred to as a discontinuous sole plate. It is a sole plate solution for rails that combines high reliability with cost-effectiveness.
Applications:
Light-duty workshop cranes
Warehouse and logistics systems
Monorail systems
Projects with limited budgets
Continuous Sole Plates
Continuous steel soleplates (long-type base plates) are laid uninterrupted along the underside of the rails. As a leading manufacturer of crane rail sole plates in China, we specialize in producing custom-made steel sole plates for continuous rail support, designed specifically for environments with heavy wheel loads, high dynamic impacts, and high-frequency operations.
Applications:
Heavy-duty overhead cranes
Steel mill cranes
Port container cranes
Gantry cranes with high wheel load
How to Choose: Continuous vs Discontinuous Sole Plates
In crane rail sole plate projects, the most critical decision is whether to choose long-type base plates (continuous sole plates) or short-type base plates (discontinuous sole plates). The wrong choice can lead to premature rail wear, foundation cracking, or unnecessary cost overruns. Based on our more than 20 years of manufacturing and project experience, this decision depends on three factors: wheel load magnitude, budget constraints, and installation conditions.
The table below compares continuous sole plates and discontinuous sole plates across seven key dimensions. If the crane wheel load exceeds 30 metric tons, heavy-duty continuous sole plate rail supports are the only safe option. When the wheel load is less than 20 metric tons, short-type base plates can reduce material costs by 50–70% while still providing reliable support. If in doubt, be sure to consult the crane manufacturer’s specifications and prioritize solutions with higher load-bearing capacity.
| Comparison | Discontinuous Sole Plates | Continuous Sole Plates |
|---|---|---|
| Wheel Load | < 20 tonnes | 30 tonnes |
| Material Usage | 1/3 ~ 1/2 of continuous | Full-length |
| Flatness | Good | Highest |
| Installation | Easier, faster | Professional installation required |
| Cost | Lower | Higher |
| Maintenance | Easy to replace | Low frequency |
| Typical Thickness | 12mm – 25mm | 20mm – 50mm |
| Clip Typ | Mostly bolted | Welded or bolted |

Frequently Asked Questions About Steel Soleplates
Continuous base plates provide full-length support and are suitable for heavy wheel loads (>30 metric tons); intermittent base plates consist of individual units spaced apart, saving 50–70% in material costs, and are suitable for light-duty applications. The choice depends on the wheel load, budget, and installation complexity.
We maintain a stock of S235JR, S275JR, S355J0, and high-quality marine-grade steel, and we also offer custom grades. All materials come with material certificates in accordance with the EN 10204 standard.
Absolutely. Customization is our core strength. We use advanced CNC laser cutting and drilling to produce custom made steel sole plates for continuous rail support. Glory Rail can precisely match your required dimensions, anchor bolt hole patterns, and specific track clamp interfaces to ensure seamless on-site assembly.
No, welding on a hot-dip galvanized surface will damage the zinc coating and compromise the integrity of the weld. The correct engineering practice is to first weld the crane rail fasteners (such as weldable rail clamps) to the exposed steel sole plates, and then send the entire assembly for hot-dip galvanizing. We offer this pre-welding service for orders of both long-type and short-type base plates.
To prevent damage and corrosion during transport, hot-dip galvanized steel soleplates are secured with steel straps and separated by wooden spacers. Anchor bolts and small crane rail fasteners are packed in sturdy, moisture-resistant wooden or plywood crates. This export-standard packaging ensures that your rail soleplates arrive intact at any port worldwide.
