Ukuhlolwa kokukhuseleka kunye nenqanaba lomdaka lokuloba

Ukuhlolwa kokhuselekoumlobothi wakho
1. The umlobothi wakho used in the lifting mechanism driven by manpower is tested with 1.5 times the rated load as the inspection load.
2. The umlobothi wakho used for the power-driven lifting mechanism shall be tested with 2 times the rated load as the inspection load.
3. Emva kweumlobothi wakhoisuswe kumthwalo wokuhlola, akufuneki kubekho iziphene ezibonakalayo okanye i-deformation, kwaye ukwanda kwinqanaba lokuvula akufuneki ukuba lidlule kwi-0.25% yobungakanani bokuqala.

4. Kubaumlobothi wakhos that have passed the inspection, a mark should be printed in the low-stress area of the umlobothi wakho, including the rated lifting weight, factory mark or factory name, inspection mark, production number, etc.

Imigangatho yescrap yeumlobothi wakhos
Inkqubo ye-umlobothi wakhokufuneka ikhutshwe xa kusenzeka enye yezi meko zilandelayo:
â ‘Qhekeka;
Amanxiba ecandelo eliyingozi afikelela kwiipesenti ezilishumi zobukhulu bokuqala;
â ‘¢ Iqondo lokuvula lenyuswa nge-15% xa kuthelekiswa nobukhulu bentsusa;
④The torsion deformation of the umlobothi wakho body exceeds 10°;
⑤The dangerous section of the umlobothi wakho or the neck of the umlobothi wakho is plastically deformed;
⑥The umlobothi wakho thread is corroded;
⑦When the wear of the umlobothi wakho bushing reaches 50% of the original size, the bushing should be replaced;
⑧ Xa mandrel yesiqwengaumlobothi wakhoinxitywe kwi-5% yobungakanani boqobo, mandrel kufuneka itshintshwe.
