Aisle width
Narrow aisles limit trolley travel and hook swing. State aisle width and the load envelope, not only the hoist tonnage.
Site and handling conditions
3 ton chain hoist with trolley
A 3 ton chain hoist with trolley changes the building more than a hook-hung replacement. Beam flange width, trolley type, end stops and remaining headroom belong in the RFQ before factories price a travelling unit. This page translates plant conditions into purchase requirements. It does not survey your building or approve a beam.
Conditions that rewrite the specification
Beam and flange
Plain, geared or motorized trolleys need the beam size. A quote that omits trolley hardware is not the same machine.
Headroom
Low roofs force low-headroom bodies. Measure hook-to-beam and lowered height instead of assuming a catalogue picture.
Power drop location
Festoon or conductor bar is site work. Keep it off the equipment line unless you ask the factory to include it.
Procurement situations, not case studies
The cards below are labelled situations used to write an RFQ. They are not completed projects, named customers or savings results.
Situation A — replace a travelling hoist
Copy beam flange, trolley wheel gauge and remaining lift. Ask whether the new trolley ships with the hoist or as a second item.
Situation B — add travel on an existing beam
Confirm the beam is already accepted by the buyer's engineer. This desk does not certify steel. The RFQ should say "trolley and hoist only".
Situation C — indoor dock staging
Dock height and weather exposure change covers and chain finish. Freight to the dock and on-site commissioning stay named extras.
| Check | If you only write this | What factories still need |
|---|---|---|
| Rated capacity | 3 ton on the nameplate | Load center and any attachment that changes the hook load |
| Lift height | A catalogue stroke | Hook-to-hook in in or mm after trolley depth |
| Travel | A photo of a trolley | Beam flange, travel length and who supplies end stops |
| Power | Electric or manual as a preference | Three-phase supply or shop air, plus lifts per hour |
| Price line | One machine number | Freight, pit depth work, anchors and commissioning named separately |
Return to inquiry options when you only need the family name, or use the contact form when beam data is ready. The units note is here.
Put trolley constraints on the RFQ
Write beam size, travel length, end-stop responsibility and whether power feed is included. We then ask factories to quote that travelling package or to exclude it in writing.
