What Buyers Must Verify Before Ordering a Crane
Before placing an order for an overhead crane, buyers have a lot to check. Getting these details right before purchase can prevent costly changes, installation delays, and safety issues. This section provides a practical pre-purchase checklist to guide your decisions.
Your crane can only perform well if the building and runway are ready. Don't assume your existing facility is automatically suitable. Take the time to verify the following:
- Runway beams and building support: Make sure the beams can handle the crane's weight plus the maximum load. Check structural drawings or have an engineer assess the support.
- Floor load capacity: If the crane's wheels or columns rest on the floor, confirm it can bear the weight without cracking or uneven settling.
- Clearances: Ensure there's enough overhead space for lifting heights and enough side space for the crane to travel freely without hitting walls, pipes, or equipment.
Tip for buyers: Walk the site yourself with your supplier or engineer to double-check these points—visual confirmation avoids surprises.
Even the best crane won't operate without the right power setup. Confirm these details before signing a purchase order:
- Voltage, phase, and grounding: Make sure your facility's electrical system matches the crane requirements. This avoids costly rewiring after delivery.
- Feeder lines and connection points: Check that the cables can carry the load and are properly routed.
- Motor compatibility: Ask the supplier if the crane's motors are rated for your electrical setup, especially if you're using variable frequency drives or non-standard voltages.
Buyer tip: Include your electrical team in discussions—early verification saves headaches during installation.
Not all cranes are built equal. Confirm that the crane you're buying is designed for your operational needs:
- Capacity: The hoist, trolley, and bridge must handle the maximum load plus a safety margin.
- Span and lifting height: Make sure these match your building dimensions and workflow.
- Datasheets and 3D drawings: Ask your supplier for detailed specs or 3D layouts if available. They help identify potential fit issues before delivery.
Practical note: Small differences in span or hook height can make installation impossible without modifications. Always double-check.
Safety isn't optional. Buyers should confirm that the crane and its components meet applicable standards before purchase:
- Regulatory compliance: Check that the crane adheres to CMAA, OSHA, ANSI/ASME B30, or CSA B167 requirements.
- Safety features: Ensure end stops, buffers, limit switches, and interlocks are included in the package.
- Documentation: Verify that manuals, maintenance schedules, and inspection checklists are provided.
Buyer tip: Ask for certificates or inspection reports to confirm compliance—don't rely solely on manufacturer claims.
A crane can only operate efficiently if nothing blocks its movement. Buyers must assess the site carefully:
- Overhead obstacles: Walk the crane path and check for pipes, ducts, lighting fixtures, or equipment that could interfere.
- Maintenance access: Ensure there's enough room to perform routine maintenance safely.
- Supplier confirmation: Ask the supplier to validate that the planned travel path accommodates the crane design.
Practical advice: Even small obstructions can cause repeated downtime or prevent the crane from reaching its full capacity. Identifying them before ordering is much easier than fixing them later.
