Kerekan

Kerekan tali modern di kapal layar.

Kerekan adalah sebuah alat mekanikal yang dipakai untuk menaikkan atau menurunkan atau hal lainnya sesuai dengan tekanan tali atau tali jaring (juga disebut "kabel" atau "kabel jaring"). Dalam bentuk paling sederhana, kereka terdiri dari gelendong (atau drum) yang dikendalikan memakai pemutar tangan.

Kerekan mengandalkan sumber tenaga dari manusia dalam hal penggunaannya, dimana alat ini biasa digunakan untuk towing dan lifting.[1]

Fungsi

Kerekan sangat cocok diaplikasikan untuk kebutuhan industri perkapalan. Alat ini bisa menarik jangkar, dimanfaatkan pada dock, hingga dapat menarik kapal para nelayan. Di industri otomotif sendiri, kerekan dipakai untuk melakukan penarikan kendaraan yang memerlukan pengecekan, seperti halnya menarik mobil yang telah terperosok ke lumpur atau sungai.[1]
