Pilihan bahan rantai gantri garpu BYD untuk keadaan kerja yang berbeza dicadangkan untuk operasi sebenar.(Rajah1)

Rantai gantri garpu adalah komponen galas beban teras forklift elektrik. Pemilihan bahannya secara langsung mempengaruhi keselamatan dan hayat perkhidmatan forklift, dan ia perlu dipadankan dengan tepat dalam kombinasi dengan keadaan kerja tertentu.

Di bawah keadaan pergudangan umum dalaman, trak forklift kebanyakannya menjalankan tugas pengendalian beban sederhana dan ringan, persekitaran kerja adalah stabil, tiada suhu, kelembapan dan faktor kakisan yang melampau, dan disyorkan untuk menggunakan rantai keluli struktur karbon berkualiti tinggi. Bahan jenis ini mempunyai keliatan yang baik, rintangan haus permukaan, boleh disesuaikan dengan irama operasi permulaan dan henti yang kerap, dan kosnya sederhana, dan memenuhi keperluan ekonomi tempat penyimpanan. Dalam amalan, minyak pelincir universal perlu digunakan dengan kerap untuk menyemak tahap haus dan lusuh rantai setiap bulan. Jika jurang rantai melebihi nilai standard, ia perlu diganti tepat pada masanya.

Keadaan pengendalian tugas berat luar adalah biasa di pelabuhan dan halaman terbuka. Forklift perlu menanggung beban besar dan kesan yang kerap. Pada masa ini, rantai keluli struktur aloi harus dipilih. Bahan ini diperkukuh oleh unsur mengaloi dan mempunyai kekuatan tinggi serta keliatan hentaman, yang boleh bertindak balas dengan berkesan kepada tegasan tegangan dan hentaman di bawah beban berat. Adalah disyorkan untuk mengutamakan pemilihan rantai yang memenuhi tahap beban yang sepadan, dan untuk mengesan ubah bentuk tegangan rantai setiap suku tahun untuk mengelakkan operasi beban berlebihan.

Dalam persekitaran suhu rendah dan sejuk, seperti gudang rantai sejuk dan operasi luar musim sejuk di utara, keluli biasa terdedah kepada risiko kerapuhan. Adalah disyorkan untuk menggunakan rantai keluli aloi keliatan suhu rendah. Bahan jenis ini masih boleh mengekalkan keliatan yang baik dalam persekitaran suhu rendah dan tidak mudah pecah akibat penurunan suhu secara tiba-tiba. Minyak pelincir khas untuk suhu rendah diperlukan untuk mengelakkan pertukaran rantai yang kerap dalam persekitaran sejuk dan panas, dan untuk memeriksa rantai untuk tanda-tanda keretakan sebelum setiap operasi.

Persekitaran yang menghakis termasuk gudang kimia, pasaran makanan laut, dsb. Media basah, asid dan alkali mudah mempercepatkan karat rantai. Adalah disyorkan untuk menggunakan rantai keluli tahan karat atau rantai tergalvani untuk merawat rantai. Bahan keluli tahan karat itu sendiri mempunyai ciri-ciri rintangan kakisan, dan rantai tergalvani mengasingkan medium menghakis melalui penyaduran. Dalam amalan, adalah perlu untuk kerap membersihkan rantai dengan agen pembersih neutral untuk mengelakkan pendedahan jangka panjang kepada cecair yang menghakis dengan kuat, dan mendapati bahawa penyaduran tertanggal atau karat terhakis tepat pada masanya.

Ringkasnya, pemilihan bahan rantai gantri perlu mengambil keadaan kerja sebagai teras, digabungkan dengan pertimbangan menyeluruh tentang beban, suhu dan kelembapan persekitaran, risiko kakisan dan faktor lain, dan pada masa yang sama bekerjasama dengan penyelenggaraan tetap untuk memastikan operasi forklift yang stabil.
