A large number of engineering after-sales cases show that 80% of the safety hazards in the hoisting of lighting fixtures are not caused by wire rope breakage, but by the failure of the locking device. When selecting in bulk, B-end procurement must avoid the three major pitfalls of poor quality.
Firstly, avoid low spec versions of soft zinc alloys. The texture is soft and the positioning is shallow, and even slight force can cause teeth to slip. After a few adjustments, it will fail and easily cause the lamp to fall.
Secondly, avoid using rough and non-standard apertures. The aperture is too large and the fit is poor, causing the steel wire rope to easily move up and down, resulting in uneven height of the lamp and a high acceptance rework rate.
Thirdly, avoid "thin structure splicing". Concentrated stress points and poor fatigue resistance, long-term suspension is prone to cracking and fracture, posing serious safety hazards.
Professional engineering grade wire locks must meet the following requirements: thick material, precise positioning, uniform locking, repeated adjustment without failure, and no damage to the steel wire rope. It is recommended to prioritize the selection of standardized products from the source factory for engineering procurement, verify the material and tensile performance, eliminate lifting safety risks from the source of accessories, and ensure smooth project acceptance.
