③ When the drum used for the lifting mechanism and the luffing mechanism has no structure that penetrates the supporting shaft in the drum, it is advisable to use steel.
④ When the wire rope on the drum is released at most during operation, the remaining part on the drum should be wound at least 2-3 times in addition to the number of turns for fixing the rope tail to avoid stress on the rope tail pressure plate or wedge sleeve and wedge block.

Frequently Asked Questions
Who should read safety inspection of the rope drum?
Plant maintenance engineers, crane service companies and buyers specifying a replacement. The note is written from workshop practice rather than from a sales brochure.
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.
