Atlas Copco Häggloader offers variety of fast, efficient excavation solutions


Atlas Copco Haggloaders—available in rubber tired, railborne or crawler models—provide efficient excavation of waste or ore in narrow tunnels and drifts.

Häggloader 10HR-B
Electro-hydraulic Häggloader continuous loaders fit almost any application by using either a backhoe or two individual arms, known as digging arms, to gather fractured material from the face into the conveyor system. The integrated conveyors transfer material continuously into a mine truck or shuttlecar. They are powered at the face by either a diesel engine or an external electrical power source.
Backhoe or digging arms
For underground applications in drifts up to 20 feet wide, the dual digging arm system is more beneficial, whereas a backhoe digging system is more useful for digging trenches. Both types are available for all Häggloaders. Customers also have the option to add an SB 152 or SB 302 hydraulic breaker when using the backhoe digging system; interchanging the two is a simple process.
Two rubber-tired Häggloader models available
Two different models of rubber-tired Häggloaders are available for quick mobility at the face. The 10HR is designed for use in drifts and tunnels with cross sections from 150 square feet and up. The 7HR is suited for cross sections measuring 75 square feet and more.
The 10HR, equipped with a 142 hp Deutz diesel engine and 100 hp electric motor, transfers material at an average rate of 4 to 5 cubic yards per minute. It can dig to widths of 11, 13 or 20 feet depending on its configuration.
The 7HR Häggloader, with a 77 hp Deutz diesel, can dig to widths of 9, 11 or 18 feet, loads material up to 3 cubic yards a minute and travels up to 6.2 mph.
Track Häggloader
The crawler-based Häggloader 9HR is engineered for use in drifts and tunnels where conditions call for the rut-less, high traction advantage of a tracked unit. The 9HR is designed for cross sections of 86 square feet and up, and can handle loads of 9 cubic yards or more per minute. It travels at up to 6.2 mph.
Rail system Häggloader
With the Häggloader 8HR and its uniquely matched HRST shuttle car system, waste and ore can efficiently be removed in long, narrow tunnels.  In most scenarios, it’s possible to remove fractured rock from an entire advance in just one trip with the Häggloader high-speed rail system, which all but eliminates the need for side niches and alcoves.
The 8HR can be ordered in three narrow rail gages: 2 feet, 2.5 feet and 3 feet. The electric motor comes in two sizes, 60 hp and 270 hp. Digging width in either version is up to 20 feet, depending on configuration of backhoe or digging arms, and it can move up to 9 cubic yards a minute.
Shuttle cars
All three shuttle car styles are available in narrow rail sizes in 2-foot, 2.5-foot and 3-foot gages. Fractured material is taken from the Häggloader by the first car and is then transferred from car to car along their integral conveyor systems, each car operating its conveyor with two 15 hp motors. (The HRST115 uses two 20 hp motors).
The HRST90 cars hold 11.75 cubic yards each, while the slightly larger HRST115 cars hold up to 15 cubic yards each. Both the HRST90 and HRST115 can handle cargoes weighing up to 24 tons.
The HRST40 will hold up to 18.3 cubic yards of material, or up to 26.5 tons.
