Bagaimana Chain Hoist Bekerja dalam Praktik?
Bagaimana cara kerja chain hoist secara detail? Sistem ini beroperasi berdasarkan prinsip mechanical advantage yang elegant namun powerful. Ketika operator menarik hand chain (pada manual type) atau mengaktifkan motor (pada electric type), putaran ini ditransmisikan melalui gear reduction system yang menghasilkan torsi besar dengan kecepatan yang terkontrol.
Langkah-langkah operasi chain hoist meliputi:
- Positioning chain hoist tepat di atas beban menggunakan trolley atau fixed mounting
- Attachment beban pada hook dengan proper rigging technique
- Pre-lift inspection untuk memastikan semua komponen dalam kondisi aman
- Gradual lifting dengan monitoring beban dan environmental conditions
- Positioning beban pada lokasi tujuan dengan presisi tinggi
- Controlled lowering dengan brake system yang responsif
- Detachment dan securing equipment pada posisi standby
Bagaimana sistem safety bekerja? Modern chain hoist dilengkapi multiple safety features termasuk overload protection yang otomatis stop operasi bila beban melebihi Working Load Limit, brake system fail-safe yang mencegah load drop, dan limit switch yang membatasi travel distance untuk mencegah over-travel.
