Memahami Overhead Cranes dan Gantry Cranes

 

 

Definisi Overhead Cranes

 

Overhead cranes merupakan sistem pengangkat yang dipasang pada struktur atap bangunan menggunakan runway beam yang terpasang pada kolom atau dinding. Bridge crane bergerak sepanjang runway dengan trolley yang melintasi bridge, menciptakan area kerja persegi panjang dengan jangkauan maksimal tanpa hambatan di lantai produksi.

Sistem ini memanfaatkan struktur bangunan eksisting sebagai titik tumpuan utama, sehingga memerlukan evaluasi struktural yang mendalam sebelum instalasi. Kapasitas angkat overhead cranes dapat mencapai ratusan ton dengan span hingga 40 meter atau lebih.

 

Definisi Gantry Cranes

 

Gantry cranes menggunakan kaki penyangga atau portal frame sebagai struktur pendukung bridge, memungkinkan operasi tanpa ketergantungan pada struktur bangunan. Sistem ini bergerak di atas rel lantai dengan fleksibilitas perpindahan lokasi sesuai kebutuhan proyek.

Desain gantry cranes memberikan kebebasan instalasi di area terbuka seperti shipyard, container yard, atau fasilitas outdoor lainnya. Variasi desain mencakup full gantry dengan dua kaki penyangga, semi gantry dengan satu kaki penyangga, dan portable gantry untuk aplikasi fleksibel.

PT Triniti Bangunindo Perkasa adalah penyedia overhead cranes dan gantry cranes berkualitas tinggi yang memahami kebutuhan spesifik berbagai industri di Indonesia. Tim ahli perusahaan siap memberikan konsultasi untuk menentukan pilihan terbaik.

Perbandingan Struktural dan Teknis

 

 

Sistem Pendukung

 

Overhead cranes mengandalkan struktur bangunan sebagai titik tumpuan, memerlukan kolom dan balok atap yang mampu menahan beban kerja dan beban mati crane. Perhitungan struktural harus mempertimbangkan defleksi maksimal dan fatigue loading untuk memastikan keamanan jangka panjang.

Gantry cranes menggunakan struktur mandiri dengan fondasi khusus untuk setiap kaki penyangga. Desain ini memberikan fleksibilitas tetapi memerlukan area lantai yang cukup untuk pergerakan kaki crane dan clearance yang memadai.

 

Jangkauan dan Area Kerja

 

Overhead cranes menawarkan jangkauan area kerja yang maksimal karena tidak ada penghalang di lantai produksi. Hook dapat menjangkau hampir seluruh area di bawah runway dengan pembatasan minimal dari struktur pendukung.

Gantry cranes memiliki keterbatasan jangkauan karena adanya kaki penyangga yang membatasi akses. Namun, sistem ini dapat beroperasi di area yang lebih luas dengan perpindahan seluruh unit crane sesuai kebutuhan.

 

Kapasitas dan Performa

 

Kedua sistem dapat menangani kapasitas angkat yang sama, mulai dari beberapa ton hingga ratusan ton. Perbedaan utama terletak pada distribusi beban dan cara transfer beban ke struktur pendukung atau fondasi.
