Key Points for Buying a Used Tower Crane
Remember these three golden rules:
Year and Working Hours: Prioritize equipment manufactured after 2015, preferably with less than 8000 working hours. Check original factory maintenance records.
Key Component Inspection: Focus on testing the wear of the hoisting mechanism brake and slewing bearing gears. The hydraulic system must be leak-free.
Complete Documentation: Special equipment registration certificate, most recent annual inspection report, and original purchase invoice are all essential.
Price Assessment and Avoidance Guide
Used tower crane prices are like a jigsaw puzzle, composed of these pieces:
Brand Premium: Mainstream brands typically have a 15%-20% higher residual value.
Depreciation Due to Operating Conditions: Outdoor-operated equipment depreciates 30% faster than indoor-operated equipment.
Configuration Differences: An 80-ton tower crane with wall-mounted equipment is 20,000-30,000 yuan more expensive than a bare crane.
Regional Price Differences: Used cranes in the Midwest and West are about 10% cheaper than those in coastal areas.
Important Considerations for Recycling Transactions
These details are invaluable when disposing of old tower cranes:
Dismantling Plan: Plan the site space in advance and confirm there are no high-voltage power lines nearby.
Transportation Costs: The total cost of dismantling and transporting a 40-ton tower crane is approximately 15,000-20,000 RMB.
Qualification Verification: The recycling party must possess special equipment dismantling qualifications.
Contract Terms: Clearly define the risk transfer points after equipment handover.
