Single Jib Portal Crane

  • Maximum Working Radius (m): 75;
  • Rated Lifting Capacity (t):
    – With hook: 650
    – Under spreader: 35/41
    – With grab: 10-50;
  • Lifting Height (m):
    – Above rail level: 10-80
    – Below rail level: 5-30;

The sturdy and compact design with larger lifting height and working radius makes it an ideal choice for large-scale operations. It is suitable for working environments such as ports, docks, shipyards, steel mills, etc.

Four Link Portal Crane

  • Maximum Working Radius (m): 55;
  • Rated Lifting Capacity (t):
    – With hook: 80
    – Under spreader: 35/41
    – With grab: 10-50;
  • Lifting Height (m):
    – Above rail level: 10-40
    – Below rail level: 5-30;

Adopts a four-linkage system (sheerleg, tie rod, boom, and counterweight beam) to maintain near-horizontal load movement. It excels in high-intensity continuous scenarios like port terminals and railway freight yards.
