A practical evidence checklist for RFQ preparation and supplier evaluation.
Compare the published product scope and source details, then include your specifications and quantity in an enquiry.
3 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
The official website shows LH hoist trolleys and QD crab trolleys, describing frame fabrication and assembly of travel and hoisting mechanisms for double-girder overhead or gantry cranes. Give rail gauge, load, headroom and control interface, define main and auxiliary hoists per project; tower crane trolley data do not apply.
Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Ask for use case, specification boundaries, supplier type, and RFQ preparation information for this product.
The trolley moves along the horizontal jib to position loads horizontally. It carries the hoisting mechanism and allows precise placement of loads within the crane's working radius.
Trolleys are typically made of high-strength steel or alloy steel. Structural steel grades such as Q235–Q345 (per GB/T 700) are often used, but the exact material must be confirmed with the manufacturer.
Typical trolley travel speeds range from 10 to 60 m/min, depending on the crane model and application. The actual speed should be verified for the specific trolley.
The trolley is driven by an electric motor connected to a gearbox and drive wheels. The operator controls the motor via signals, and braking systems (mechanical or electrical) stop and hold the trolley. Some systems use rack-and-pinion or friction drives.
