The problem: half a building
The stockyard handles H-beams and plates. One side is under a warehouse roof, the other is open storage. A full gantry would have needed rails and foundations on both sides, taking up yard space; a bridge crane would have needed new brackets on a wall that was not designed for them.
What we specified
A semi-gantry crane: one end runs on a ground rail, the other on a runway beam fixed to the existing warehouse columns. That halves the civil work and the footprint, and it suits a yard where one wall already exists.
The crane was built for the local 440 V / 60 Hz supply. Before production, we checked the column and runway capacity with the customer, because a semi-gantry puts load into the building structure on one side.
What was delivered
- 1 × 5 t semi-gantry crane, 15 m span, 9 m lift
- Rail foundation drawing and wheel load data
- Radio remote control
- Spare parts pack
- Pre-shipment video: main girder dimensions, camber check and no-load travel
Why the pre-shipment video mattered
The customer had not bought from China before and wanted proof of the main dimensions and camber before the crane was loaded. We recorded the girder length, camber measurement and no-load travel, and sent the video before container loading.
The crane was approved from that video, then packed and shipped.
Result
One crane covers the covered storage and the open yard, with one rail on the ground and one on the existing wall. Rail and foundation work was roughly halved compared with a full gantry.
Contract to shipment: 35 days.
