Schöller Special Machines

Special conversion with elevating cabin, including straightening and extension of the main boom, extra tail weight (+ 1,500 kg) as well as various extras for demolition and dismantling applications.

Full conversion of a wheeled excavator for underground application in a mineral mining operation. The conversion comprises a reinforced upper structure and undercarriage, an increase of the hydraulic oil volume at the auxiliary control circuit for operation of high-performance attachment tools, optimization of the hydraulic and electrical installation for underground applications, etc.

Conversion to a crawler undercarriage with hydraulically telescopic chassis (adjustable in width), for application in sewer and pipeline construction.

Special conversion with extra tail weight (+ 1,500 kg), which can be set down and detached hydraulically in order to reduce the transport weight of the machine.

Conversion of a crawler excavator with special boom for underwater excavation work. Extended basic boom and new special dipper arm with flow-optimised profile and sealed bearings for underwater use.

Conversion of the boom equipment to an adjustable extension of the main boom with hydraulic locking (3 settings). The system serves to increase the boom reach height when the main boom position is at its full extension.

The higher tailboard with integrated hydraulic tailgate increases the loading capacity of the dumper and reduces falling material when driving on steep ramps.

Conversion for heavy-duty applications in tunnel construction - heavy-duty loading shovel - additional heavy-duty ram protection at the rear part of the carriage - ram protection grid, hinged (engine hood can still be opened) - semi-automatic fire extinguishing system for the engine compartment - sturdy cab front protection grid (hinged for windshield cleaning) - extra flashlights at the rear of the machine - Optional: emergency stop at the rear of the machine (right + left) and in the cabin - Optional: Blaxtair collision and person recognition system for the rear and side areas - Optional: 360° camera monitoring system, including data recording

A compact excavator with diesel and emission-free electronic drive (SSM Twin-Drive) is available both as a conventional compact excavator for standard applications and in the tunnel version. This Twin-Drive excavator can be operated fully diesel-hydraulically as usual. The additional integrated electric drive allows emission-free operation on site - a normal construction site connection with 400 volts and 32 amps is completely sufficient. This allows continuous use of the machine in electric mode, without restrictions due to limited battery capacity or charging times.

Special conversion with hydraulically adjustable elevating cabin that features an elevating function for optimum view of the boom when carrying out demolition and dismantling work.

Compact crawler excavator with electric drive, remote control, and camera monitoring. Special conversion for applications in shaft sinking and tunneling at a mine. - emission-free electric drive for better ventilation on-site - cable reel at the cabin roof for power supply of the excavator - remote control to operate the excavator from a platform or at a safe distance from the extraction area - camera-monitoring system for safe operation of the machine in areas with blind spots - machine can be dismantled for transport in shafts (D = 1.9 m) - selection of various attachments, quickly changeable - machine can be converted back to conventional diesel drive

Conversion with hydraulically adjustable tilting cabin for improved and more convenient view of the boom, particularly when carrying out demolition and dismantling work.

The current product range comprises five crawler tunnel excavators with an operating weight of seven thru 47 tons as well as one wheeled tunnel excavator with an operating weight of 20 tons. All tunnel excavator models are based on trusted and reliable Volvo basic machines and are equipped with diesel drive as standard; optionally, they are also available with an emission-free electric drive. The compact excavators have a short tail-swing and operate with high efficiency; therefore, they are ideally suited for small to large tunnel cross-sections. Due to the modular built of the boom equipment, they can be adapted to different tunnel heights, giving them maximum flexibility. The high hydraulic output of the Volvo machines allows operation of efficient attachment tools, like hydraulic hammers, rock cutters, demolition shears, to name only a few, These can be changed quickly with quick-change devices.
