QD 16/3.2–20/5 t Slow-Speed Overhead Crane
Use a slow main hook and a faster auxiliary hook for controlled heavy placement. The 16/3.2 t and 20/5 t references have different main and auxiliary hook heights. Compare the complete load and which hook performs each lift.
Where 16–20 t slow-speed QD crane fits the lifting task.
The 16/3.2 t and 20/5 t references have different main and auxiliary hook heights. Compare the complete load and which hook performs each lift.
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.

Before you release a purchase order.
Use these questions to compare suppliers against the same technical and delivery scope.
May the main and auxiliary hooks lift together?
Only if the specific crane is designed, rated and controlled for combined lifting. Do not add the hook ratings.
Which hook height belongs on the drawing?
Show separate main and auxiliary hook envelopes and the lowest pickup elevation.
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.
