Katrol ini biasanya dibuat dengan menggunakan bahan dan proses yang berbeda, seperti besi tuang, baja tuang, atau pelat baja canai, untuk memenuhi persyaratan khusus untuk kekuatan, ketahanan aus, dan sifat ringan, tergantung pada kondisi kerja.<\/p>\n<ul>\n<li><strong>Katrol Tetap<\/strong>: Terutama berfungsi untuk mengubah arah gaya tanpa mengurangi tenaga. Prinsip katrol tetap didasarkan pada tuas lengan yang sama, di mana lengan daya dan lengan penahannya sama, yang berarti tidak menghemat atau membutuhkan tenaga ekstra untuk beroperasi. Dalam situasi di mana berat tali dan gesekan antara tali dan katrol dapat diabaikan, katrol tetap dapat menjaga arah gaya tali tetap konstan, yang sangat penting untuk pengangkatan objek yang stabil.<\/li>\n<li><strong>Katrol Bergerak<\/strong>: Diinstal pada <a href=\"https:\/\/www.hnhlcrane.com\/id\/product\/overhead_crane_hook\/\" target=\"_blank\" rel=\"noopener\"><strong>kait derek<\/strong><\/a>. Ketika mengangkat beban dengan katrol yang dapat digerakkan, ini dapat menghemat setengah tenaga tetapi membutuhkan penarikan dua kali lipat jarak tali kawat. Prinsip di balik katrol bergerak adalah bahwa beban ditopang oleh dua segmen tali, dengan masing-masing segmen hanya menanggung separuh beban, sehingga memberikan efek penghematan tenaga.<\/li>\n<li><strong>Blok Katrol<\/strong>: Terdiri dari beberapa katrol tetap dan bergerak, memungkinkan kombinasi manfaat penghematan gaya dari katrol bergerak dan perubahan arah yang disediakan oleh katrol tetap. Hal ini memungkinkan pengurangan gaya dan perubahan arah, sehingga memungkinkan pengangkatan beban berat yang lebih efisien. Prinsip kerja blok katrol didasarkan pada kombinasi fitur penghematan tenaga dari katrol bergerak dan kemampuan mengubah arah dari katrol tetap.<\/li>\n<\/ul>\n<h6><strong><span style=\"font-size: 18pt; font-family: arial, helvetica, sans-serif;\">Standar Pembuangan Katrol Derek Overhead:<\/span><\/strong><\/h6>\n<ul>\n<li><strong>Kenakan<\/strong>: Jika keausan pada katrol melebihi 10% dari dimensi aslinya atau mempengaruhi fungsi tali kawat.<\/li>\n<li><strong>Retak<\/strong>: Adanya retakan, khususnya di area kritis seperti alur atau flens.<\/li>\n<li><strong>Deformasi<\/strong>: Deformasi yang nyata, seperti pada alur atau flens, yang berdampak pada pengoperasian normal.<\/li>\n<li><strong>Fraktur Kelelahan<\/strong>: Terjadinya fraktur kelelahan di bagian manapun dari katrol.<\/li>\n<li><strong>Korosi<\/strong>: Karat yang melebihi 5% dari dimensi aslinya.<\/li>\n<li><strong>Kelonggaran<\/strong>: Bantalan longgar atau rusak.<\/li>\n<\/ul>\n<p>Bentuk dan ukuran penampang melintang dari <strong>alur pada katrol derek di atas kepala<\/strong> secara signifikan memengaruhi keandalan dan masa pakai tali kawat. Dinding alur harus halus untuk menghindari tali terbelit, sehingga memastikan pengoperasian yang aman.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-4661\"
