Kobelco BM1000HD

The Kobelco BM1000HD is a heavy-duty 100-ton class crawler crane designed for intensive foundation and material handling applications. It excels in diverse site environments, particularly where deep foundation or clamshell work is required. The crane’s lattice boom system offers modular lengths from 13.8 meters up to 62.6 meters, supporting a maximum lifting capacity of 100 metric tons at 3.8 meters radius.

For foundation operations, the crane can also be configured with clamshell or hammer grab setups:

• Clamshell boom: Up to 26.0 m, with a lifting capacity of 12.5 t at 13.0 m radius.
• Hammer grab boom: 23.0 m, lifting up to 50.9 t at 7.0 m radius.

The crane is powered by a Hino P11C-UN engine—a turbocharged, direct-injection 10.5-liter diesel engine that delivers 247 kW (331 hp) at 2000 rpm and 1,300 Nm of torque. This engine meets NRMM (EU Stage IIIA) and EPA Tier III emissions standards. The hydraulic system comprises three variable displacement piston pumps, generating 31.9 MPa pressure for hoisting and travel systems.

Dual winches provide:

• Line speed: 3 to 110 m/min (first layer)
• Rated line pull: 132 kN (13.5 tf)

Maximum line pull: 252.9 kN (25.8 tf) Each winch uses 28 mm wire ropes, and the drums are grooved to hold up to 200 m (main) and 130 m (auxiliary) rope lengths. Braking is achieved via forced-circulation oil-cooled wet-type multi-disc systems offering both positive and negative control.

The crane’s swing system allows 360° continuous rotation at up to 3.2 rpm, operated via a hydraulic motor with planetary reduction and a spring-set parking brake.

Crawler mobility is provided by independent hydrostatic drives on each side, with 900 mm wide track shoes. The crawler frames are hydraulically extendable for wide-track operations and retractable for transport. Travel speeds reach 1.5 km/h, and gradeability is rated at 30%.

The fully enclosed operator’s cab features ergonomic controls, an air-conditioning system, LCD displays, a load moment indicator with over-hoist protections, and multiple operator comfort fittings such as a sun visor, cup holder, and shoe tray.

The total operating weight is approximately 107.4 tons, with:

• Upper counterweight: 37.8 tons
• Carbody weight: 6.8 tons
• Crawler weight: 3.2 tons

The Kobelco BM1000HD is a powerful and adaptable crane for large-scale lifting and foundation tasks. With advanced hydraulics, extensive boom configurations, and intelligent control systems, it’s built to perform under the most demanding project conditions.
