Frequently Asked Questions
Are your cranes built to FEM and DIN standards?
Yes. Sinomac designs to FEM, DIN and ISO. Duty group is set from your real lifting cycle, so the classification on the nameplate matches how the crane is actually used.
Can you supply a crane kit instead of a complete crane?
Yes. Sinomac supplies hoist, end carriages, drives, control system and anti-sway as a kit, and provides free production drawings of the girder for regional partners and clients buying kits, which lowers shipping cost.
How fast do you quote?
Sinomac provides a crane quotation within 24 hours and a CAD drawing within 48 hours.
What documentation ships with the crane?
Equipment qualification certificate, main parts qualification certificates, electrical drawing diagram, installation operation and maintenance manual, and installation and commissioning instructions.
Can we inspect before shipment?
Yes. Every hoist is pre-commissioned before packing and the crane is pre-assembled for a factory acceptance test. Clients are also welcome to appoint a third party inspection.
