Do GRC Components of Different Weights Require Different Installation Methods? Differentiated GRC Component Installation Solutions

GRC components are installed in three weight classes: ≤50kg can be installed manually, 50-200kg requires mechanical assistance, and >200kg must be mechanically hoisted. Lifting point placement must be calculated, with hoisting stress ≤ 1/5 of the material's tensile strength and a rigging safety factor ≥ 6.

Weight-based classification management reduced installation accident rates by 90%. A 3-ton GRC column on one project used 4-point lifting (sling-to-horizontal angle ≥ 60°), achieving installation precision of ±2mm. In a contrasting case where 2-point lifting was used in violation of regulations, the component cracked and had to be scrapped.

Manual Installation Range

Weight ≤ 50kg; installation height ≤ 3m; these ranges are suitable for manual installation.

Mechanical Assistance Requirements

Weight 50-200kg; use of electric hoists; these requirements ensure safety.

Mechanical Hoisting Standards

Weight > 200kg; professional lifting plans; these standards ensure safety.

Key Safety Control Points

Hoisting stress control; rigging safety inspection; these points prevent accidents.

Installation methods must be tailored to the job. Qinglong GRC follows standardized construction—safe and efficient.
