Q1: What is the core difference between WA6013-6A and 8B?
A: 6A is a 6t standard model, focusing on versatility; 8B is an upgraded model, with short boom length (e.g. 30m) lifting up to 3.9t, which is more suitable for the lightweight and high-precision requirements of PC construction.
Q2: Can it be used in highland areas?
A: The standard model can be used in altitude ≤1000m (ambient temperature - 20℃~+40℃), and the heat dissipation and insulation system needs to be customized for super plateau.
Q3: What is the maximum height of attached installation?
A: 190m (7 attachments are required, and the highest suspended height is ≤27.1m), and braces (horizontal reaction force is ≤360kN) need to be configured according to the “Technical Requirements for Attachment”.
Q4: How to evaluate the remaining life of used equipment?
A：Refer to the maintenance records (e.g. oil change cycle of reducer 3000 hours / 2 years), weld inspection of structural parts (no cracks, deformation), and wear of steel wire ropes (scrapping standard: breakage of more than 10% of the wire or reduction of diameter by 7%).
