Overhead crane assembly is a critical service for manufacturing plants, warehouses, and industrial facilities that require safe, precise material handling at height. At LMM, we specialize in assembling overhead crane systems that meet the load requirements, span dimensions, and operational demands of our clients. Whether installing a brand-new system or modifying an existing one, our team ensures each crane is assembled to perform reliably and safely.
Planning and Site Preparation
Every successful overhead crane assembly starts with a detailed plan. We begin by evaluating the building structure, load paths, and clearances to determine whether it can support the crane system. This includes reviewing existing engineering drawings or conducting a site survey to identify any reinforcements needed.
Our team creates a lift plan outlining how each crane component will be delivered, staged, and installed. We coordinate with plant managers and contractors to minimize downtime and disruption to ongoing operations. We also handle any required permits and ensure all staging areas are safe and compliant with OSHA regulations.
Component Assembly and Installation
Overhead crane systems consist of several critical components: runways, bridge beams, hoists, end trucks, controls, and electrical systems. Our assembly process begins with the proper alignment and anchoring of runway beams, which serve as the foundation for the crane’s movement.
Next, we install the bridge and trolley systems. Bridge beams are lifted and secured into place using mobile cranes. The hoist and trolley unit is then mounted, allowing horizontal travel across the span. Our technicians align and secure all hardware, ensure motor and gear connections are correctly configured, and install wire management systems to protect cables and limit wear.
We use certified rigging and lifting equipment to move each component into place with precision. For multi-span or double girder systems, we coordinate tandem lifts and staging with advanced lift plans to ensure structural safety.
Testing, Calibration, and Certification
Once installation is complete, we test every part of the overhead crane system to verify safe operation. This includes running the hoist and trolley, checking braking systems, testing limit switches, and inspecting wire ropes or chain conditions. Load testing is conducted using calibrated test weights to validate lifting capacity under operating conditions.
We perform electrical system checks to ensure all controls function properly, including pendant controls, radio remote systems, and variable frequency drives (VFDs) where applicable. Our team calibrates the hoist and travel speeds as needed and sets up safety interlocks.
After testing is complete, we provide full documentation of the assembly process, load testing results, and operator certification records. This documentation supports OSHA and ANSI compliance and serves as a baseline for future inspections or maintenance.
Ongoing Support and Modifications
After initial assembly, many facilities require adjustments to accommodate changing workflows or increased production demands. We offer overhead crane modification services including rail extensions, hoist upgrades, and automation enhancements.
In addition, we provide preventative maintenance and inspection programs to help facilities maintain compliance and extend equipment life. Our team also responds to emergency service calls for operational issues or damage from overloading or collisions.
Whether you’re expanding your facility or upgrading a worn-out crane, we ensure that any modifications are integrated seamlessly with your current equipment and building structure.
