Custom Machine Bases for Oversized Equipment
Heavy industrial equipment puts massive stress on floors and foundations. Standard bases crack, allow equipment to shift, or cannot handle the vibration from large pumps and generators. Most fabricators don’t have the capacity to build bases for equipment that weighs over 100,000 pounds.
At Custom Engineering, we’re an ISO-9001:2015 manufacturer that fabricates custom machine bases for oversized equipment. Our bases keep machinery stable and prevent floor damage for decades. Read on to learn more about how we build custom machine bases to match your equipment’s size, weight, and operating forces.

How Custom Machine Bases Support Heavy Equipment
Industrial equipment such as generators, pumps, compressors, and transformers generates tremendous forces during operation. Machine bases (also called baseplates or soleplates) sit beneath this equipment to distribute weight, control vibration, and prevent movement. Without proper bases, heavy machinery can damage floors, become misaligned, or transmit excessive vibration to surrounding equipment.
Properly fabricated or manufactured bases perform several important functions:
Weight Distribution: Bases spread concentrated loads across a wider footprint, preventing localized floor stress and structural damage.
Vibration Control: Stable base construction helps reduce vibration transfer from operating machinery into the floor, structure, or surrounding equipment.
Equipment Stability: Bases anchor machinery in position and prevent shifting or movement during continuous operation.
Floor Protection: The baseplate creates a barrier between heavy equipment and the facility floor or ground surface.
Pressure Management: Bases distribute downward forces across the entire mounting surface rather than concentrating pressure at specific points.
Custom Engineering Builds Durable Machine Bases
At Custom Engineering, we manufacture machine bases that require heavy-lifting capacity and specialized fabrication equipment, based on customer-supplied drawings or specifications. Our Erie facility supports large weldments over 60 feet long and up to 160,000 pounds through precision fit-up flooring systems built for close-tolerance fabrication. Machine base and skid projects range from 2,500 to 130,000 pounds.

This combination of heavy-lifting capacity, precision systems, and high-level certifications makes us a premier supplier for large-scale industrial machine base projects.
Our Custom Machine Base Designs
The equipment’s size, weight, mounting points, operating forces, and installation location determine the machine base requirements. Our engineering and design personnel work directly with customers to review the end application, environmental conditions, applied forces, and applicable industry standards to ensure that the supplied drawings or specifications can provide adequate support.
That review helps define the base geometry, mounting approach, structural configuration, and finish requirements. Custom Engineering does not design or engineer custom machine bases, but will work closely with your team to develop a comprehensive strategy to deliver the components and results you need.
Some projects require unique shapes, special specifications, protective finishes, or heavy I-beam configurations. Each design choice reflects the equipment and the operating environment. The final base provides the customer with a support structure tailored to the application, rather than a generic platform.
Large Baseplate and Skid Fabrication
We manufacture baseplates, soleplates, foundation plates, platforms, and skids through in-house heavy metal fabrication. These structures give customers the physical base components required for large industrial equipment projects. Our Erie facility gives us the space, equipment, and process control needed to build custom machine bases for oversized equipment.
Baseplates and soleplates serve as machine support surfaces, while foundation plates and platforms create larger structural support areas. Skids provide fabricated structures for the transport, placement, or installation of equipment. Each structure type provides the project with a defined support component before welding, machining, inspection, or final assembly.
Machining Base Mounting Surfaces
Machining prepares fabricated machine bases for precise equipment mounting. CNC and manual operations can mill, bore, drill, tap, baseplates and sole plates to match customer specifications.
Our machining capabilities support projects exceeding 720 inches in length and 186 inches in width, including work on baseplates and sole plates. Custom Engineering machines carbon steel, stainless steel, aluminum, alloy steel, copper, and other industrial materials.
Welding Standards for Machine Bases
We maintain over 180 qualified welding procedures for complex fabrications and heavy weldments. These procedures are qualified in accordance with ASME Section IX, AWS D1.1, AWS D1.6, and other codes of construction. Certified welding inspectors and welding engineers support compliance and quality control on complex welding projects.
Our team uses GMAW, FCAW, SAW, GTAW, and SMAW for welded machine base work. Manual and semi-automatic welding methods give Custom Engineering the flexibility to create custom base configurations.
Our Quality Control Systems
Our ISO 9001:2015 quality program supports machine-based projects through controlled documentation, detailed work instructions, inspection procedures, and corrective action processes. Manufacturing specifications remain documented throughout fabrication, machining, welding, and inspection. The program monitors work, records nonconformities, and initiates corrective action when needed.
We use five non-destructive examination methods to evaluate materials, welds, and machined surfaces on fabricated projects: visual examination, magnetic particle testing, liquid penetrant testing, ultrasonic testing, and radiographic testing. FARO laser tracking measures 3D coordinates and verifies geometric dimensioning and tolerancing on machined surfaces. The portable unit can check jobs while still on the machine and electronically store measurements for project records.
Choose Custom Engineering for Custom Machine Bases
Heavy equipment can’t be mounted directly on facility floors without causing damage. A custom-designed machine base spreads forces across a wider area and keeps everything anchored.
Custom Engineering builds machine bases beyond typical fabrication limits. Your base arrives ready to install and prevents floor damage throughout your machinery’s service life. Click below for a quote on custom machine bases.
