QD 32/5–50/10 t Slow-Speed Overhead Crane
Place heavier equipment using a slow main hook and a separately rated auxiliary hook. The 32/5 t and 50/10 t examples differ in hoist speed, trolley mass and recommended rail. Structural approval needs the selected wheel-load schedule.
Where 32–50 t slow-speed QD crane fits the lifting task.
The 32/5 t and 50/10 t examples differ in hoist speed, trolley mass and recommended rail. Structural approval needs the selected wheel-load schedule.
Include rigging, carrier beam or service attachment, not only the payload.
Provide rail centres, travel length, hook approach and obstructions.
State frequency, shifts and precision or transfer requirements.

Separate factory inspection, dispatch, freight, installation, site load test and operator documents.
Before you release a purchase order.
Use these questions to compare suppliers against the same technical and delivery scope.
Can an existing runway accept this crane?
Check wheel loads and horizontal reactions for the exact span, hook package and duty before ordering.
Do the two hooks add to a combined capacity?
No. A combined lift needs a separately rated and documented procedure and control design.
What is the minimum order?
Request a quotation for one crane or a project package; the offer should state the minimum quantity and complete supply scope.
How is lead time confirmed?
Ask for calendar days from deposit and approved drawings to factory dispatch, with freight and site work shown separately.
