Fanaraha-maso ny fiarovana nyfarango
1. The farango used in the lifting mechanism driven by manpower is tested with 1.5 times the rated load as the inspection load.
2. The farango used for the power-driven lifting mechanism shall be tested with 2 times the rated load as the inspection load.
3. Aorian'ilayfarangonesorina tamin'ny enta-mavesatra fanaraha-maso, tsy tokony hisy lesoka na fahasimbana miharihary, ary ny fisondrotana ny diplaoma fanokafana dia tsy tokony hihoatra ny 0,25% amin'ny habe voalohany.

4. Ho an'nyfarangos that have passed the inspection, a mark should be printed in the low-stress area of the farango, including the rated lifting weight, factory mark or factory name, inspection mark, production number, etc.

Fenitra manala ho an'nyfarangos

â ‘¢ Ny diplaoma fanokafana dia nitombo 15% raha oharina amin'ny habe tany am-boalohany;
④The torsion deformation of the farango body exceeds 10°;
⑤The dangerous section of the farango or the neck of the farango is plastically deformed;
⑥The farango thread is corroded;
⑦When the wear of the farango bushing reaches 50% of the original size, the bushing should be replaced;
⑧ Rehefa ny mandrelin'ny sombin-javatrafarangodia mitafy hatramin'ny 5% amin'ny habeny tany am-boalohany, tokony soloina ny mandrel.
