Q1:What are the standard fixing methods for basket counterweights?
A: The standard fixing methods for basket counterweights include: using special bolts to fix the counterweight blocks on the basket balance arm, the bolts shall meet the 8.8 - grade high - strength standard, and each counterweight block shall be fixed with at least 2 bolts; for stacked counterweight blocks, horizontal connecting rods or baffles shall be set to prevent the counterweight blocks from sliding sideways; after the fixing is completed, it is necessary to check whether all connecting parts are tight to ensure that the counterweight blocks do not loosen or shift during the operation of the basket.
Q2: How do high - temperature environments affect basket counterweights? What protective measures should be taken?
A:High - temperature environments (such as outdoor operations in summer) may cause the evaporation of water inside the concrete counterweight blocks, resulting in cracks or a decrease in strength; at the same time, high temperature will accelerate the oxidation and corrosion of metal connectors, affecting the fixing effect. Protective measures include: using high - temperature resistant concrete materials to make counterweight blocks, and applying sun protection and heat insulation coatings on their surfaces; regularly checking whether the counterweight blocks have cracks, spalling and other phenomena, and timely replacing the damaged counterweights; regularly derusting and anti - corrosion treatment of metal connectors, and applying high - temperature resistant lubricating oil.
Q3: What are the hazards of insufficient basket counterweights? How to avoid it?
A: Insufficient basket counterweights will reduce the overall stability, which is likely to cause overturning accidents, resulting in casualties and equipment damage. The ways to avoid it are: strictly in accordance with the basket instruction manual and relevant specifications, accurately calculate the required number of counterweights according to the actual load (including personnel, tools and materials), conduct weighing verification before installation, ensure that the total weight of counterweights is not less than the calculated value, and it is strictly prohibited to reduce counterweights without authorization.
