World of Concrete

The Brokk 100 demolition machine was launched at the World of Concrete in Las Vegas.35% great breaking power for latest Brokk

The Brokk 100 demolition machine was launched at the World of Concrete in Las Vegas. The new unit is more compact but provides a 35% greater breaking power. It is a replacement for the Brokk 90.

The Brokk 100 is designed for use in a variety of industries including cement and metal processing, construction and demolition, mining and tunnelling, and nuclear, as well as other applications.

A brand new digital remote-control box allows the operator to stay clear of any hazards on the jobsite, and monitor some of the key functions of the machine on an LCD display. In their statement, Brokk say that the new machine is the first in the industry to deliver the flexibility of true 360° working performance, without compromising stability, productivity or reliability.

The compact design enables operation in the tightest, most confined spaces. The low-profile configuration, less than 1.22 m (4 ft) high, allows access into smaller openings. Centre of gravity has been lowered for greater stability. Improved driving capabilities further enable the machine to offer smooth transportation and operation on the most challenging jobsites.

Though the overall design is smaller, power and reach were not sacrificed. A new load-sensing hydraulic system with improved hydraulic capacity helps generate 35% greater breaking power when paired with the included SB152 breaker. Maximum horizontal reach is 3.69 m (12 ft,) while vertical reach is 4.3 m (14 ft).

It is powered by a 14.91 kW (20 hp) electric motor, allowing safe, emissions-free operation. Two power levels are offered: 16 and 32 amp. When electric power supply is limited, the machine offers the option to “gear down” and work using only 16 amps. Excluding attachments, the Brokk 100 operating weight 990 kg (2,183 lbs). Recommended maximum weight of attachments such as breakers, crushers, drills and shears is 190 kg (331 lbs).

Atlas Copco’s FlexiROC T15 R drill rig, which is used for a wide variety of small-scale drilling jobs such as preparing building sites and trenching, has now considerably expanded its field of application.Atlas Copco drill rig with unique rollover feed system

One of the smallest radio controlled drill rigs in the Atlas Copco range has now become one of the most versatile with the addition of an innovative rollover feed system.

Atlas Copco’s FlexiROC T15 R drill rig, which is used for a wide variety of small-scale drilling jobs such as preparing building sites and trenching, has now considerably expanded its field of application.

The reason is a completely new boom concept which enables the rig to switch from downwards drilling to upwards drilling in one easy operation. This facility is extremely easy to use. All the operator has to do is put the rig into tramming mode, remove a locking pin, push the feed round 180 degrees, replace the pin and start drilling once again.

This procedure, called re-pinning, takes just a few minutes and enables the rig to be used in eight different configurations, including toe-hole drilling at various angles, upwards or downwards. The switch is also safe to carry out as the feed beam is in a resting position while the re-pinning is being done.

“The FlexiROC T15 R is now even more valuable to have in the fleet,” says Erik Ahlström, Product Responsible Service Engineer at Atlas Copco Surface Drilling Equipment. “With a great vertical coverage area of 18 square meters it can go from drilling vertical holes to horizontal toe-holes and then to upward drilling, for example, rock reinforcement all from the same set-up.”

The rig is also extremely economical to run thanks to its high-torque Cummins B3.3 (Naturally Aspirated) diesel engine. During tests in Sweden with 47 % active drill time drilling 45 mm holes in hard granite, the recorded fuel consumption was less than 5.7 litres per hour.
