What Are the Transport and Access Limits for a Transformer?
Quick answer — A large transformer is limited by road and rail weight/height/width, the bridge and turning constraints, the crane capacity, and the substation access and clearance. The transformer is shipped on a specialised transport frame or barge, and the route and site access are surveyed to confirm the weight, dimensions, lifting and the drop. These constraints can limit the size that can be delivered.
What transport and site-access limits apply to a large transformer?
Weight and dimensions
The weight and the overall dimensions set the transport mode and the route; a road or rail limit can dictate the maximum size or the shipment method (e.g. by barge).
Route and site survey
The route, bridges, corners, tunnels and the substation access and crane are surveyed so a unit can be delivered and positioned.
Lifting and access
Confirm the crane capacity, the access, the foundation and the clearances so the unit can be set in place.
