Solution
Crane Customization
From workshop drawing to a crane specification in four steps
Most enquiries arrive as a building and a load, not a crane model. Sinomac works back from the workshop drawing to the crane.
How It Works
Step 1 — Tell Us the Industry
General manufacturing, steel mills, power and renewable energy, cement glass and precast concrete, automotive, aerospace, warehousing and logistics, or construction and infrastructure. The sector sets the duty group starting point and the environment rating.
Step 2 — Maximum Lifting Capacity
From up to 2 tons through 3, 5, 10, 15, 20, 32 and 50 tons, to over 50 tons. State the heaviest routine lift rather than an occasional exception, then note the exception separately.
Step 3 — Span
Up to 6 m, 10 m, 20 m, 30 m, 40 m or beyond, measured rail centre to rail centre. If you are unsure, the workshop drawing gives us the number.
Step 4 — Send the Workshop Drawing
Share the drawing by email or WhatsApp. Sinomac returns a crane quotation within 24 hours and a free CAD drawing within 48 hours, so your structural engineer can verify the runway and wheel load before you commit.

View specificationFrequently 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.
