The Multicrete Raise Robot®
The Multicrete Raise Robot® Robotic Raise Applicator is a remotely controlled robotic assembly for the spraying of shotcrete; used in shafts and raises of subterranean excavations. This robotic unit is designed for use in mines and on large civil construction projects.
The standard Multicrete Raise Robot® is designed for use in raises a minimum of 1.5 meters diameter up to a maximum of 10 meters diameter. Hydraulic retractable arms stabilize the The Multicrete Raise Robot® and allow for undulations along the interior surface of the raise.
Operating Principle
The Multicrete Raise Robot® is lowered by means of a heavy-duty incremental winching system. This system allows for variable speeds from 5 cm/minute up to 6 m / minute.
During its descent, the Multicrete Raise Robot® washes (hydro-blasts) the interior surfaces, as wel as videotapes the entire raise.
On its return, the unit commences spraying shotcrete in a uniform single pass. The electric motor on the spray head allows for 360° non-stop rotation.
Application of Shotcrete
The Multicrete Raise Robot® is used in conjunction with the Aliva electric powered shotcrete machine mounted on a Multicrete Integral Predampener.
Predampened material is conveyed through 50-65 mm. diameter heavy duty hose for the remote application of shotcrete via the Multicrete Raise Robot®.
At surface level, technicians monitor the progress of the Multicrete Raise Robot® via video display. This allows for the rate of application to be modified without personnel entering the raise.
Shipment
All the required equipment, spares and accessories can be compacted for shipment into a 20’ sea container. The Multicrete Raise Robot® collapses to just 1.8 meters in height, 2.7 meters in length and 1.8 meters in width for ease of transport.

Multicrete HW10H Hybrid-Wet™ Shotcrete Carrier
Aliva® Shotcrete Machine, AL-302 Spray Arm on Carrier
A shotcrete carrier includes a dry mix hopper, a wet mix shotcrete spraying machine, and a mixing auger for wetting the dry mix as it is conveyed from the dry mix hopper to the shotcrete spraying machine on a common mobile frame.
The shotcrete spraying machine comprises an inlet hopper receiving the wet mix shotcrete from the mixing auger, and a rotor with chambers rotatable from a loading position in communication with the inlet hopper and a discharging position in communication with a pneumatic conveying line. The pneumatic conveying line conveys the wet mix shotcrete to a nozzle commonly supported on the mobile frame.

Pre-dampener and Aliva Dry Mix Shotcrete Machine Combination
This easily transported Multicrete™ Integral Shotcrete Unit consists of an Aliva dry mix shotcrete machine and a Multicrete™ Predampener, mounted together on a common frame. Preparation includes connecting the “Bull Hose” from the air supply to the inlet on the predampener frame. The water line is then connected to the spray nozzle assembly located on the mix auger. Finally, the material delivery hose can be attached to the outlet chamber assembly of the Aliva pot and shotcreting can proceed.
Purpose
The Hopper on the Predampener allows for a continuous feed of pre-blended dry mix shotcrete – even during bulk bag changes. The feed auger located under the hopper then feeds a mix auger where water is added to suppress dust and to allow the nozzleman to easily regulate the water at the nozzle.
Power Options
Electric
- 5 hp helical snuggler gear motor to mix auger.
- 3 hp variable speed motor to cross feed auger.
- Centrally mounted electrical control panels.
Pneumatic
- 2” filter/regulator/lubricator system.
- 12 hp vane motor, helical worm gear reducer to mix auger.
- 7 hp vane motor, helical shaft mount reducer to feed auger.

Dry and Wet Shotcrete
The AL-257 is the universal machine for the application of dry- and wet shotcrete in the thin-stream method. The new and very compact design of the machine impresses through its dimensions, weight and performance. With just 750 kg and dimensions as little as a small dry shotcrete machine, the AL-257 fits on every job site and is easy to install and operate. With its unbelievable output capacity range from 0.7– 9.6 m3/h (with 3 rotor sizes) the machine works on small concrete renovation work as efficient as on big slope protection or in mines. Less maintenance and wear cost makes it the ideal shotcrete machine for all applications.
Fields of application:
- Wet- and dry shotcrete application
- Concrete renovation
- Joint-fillings
- Swimming ponds, swimming pools
- Slope protection, rock consolidation
- Canal-renovation (sewage)
- Mining and tunnel applications
With the newly developed, universal AL-257, dry- and wet shotcrete are equally possible. No changing on the machine from dry to wet shotcrete has to be performed.
For changing from wet to dry shotcrete, the machine has to be cleaned and dried up. The integrated exhaust system and a newly designed hopper allow a high filling degree of the rotor chambers, which leads to low pulsation and less rebound.
The AL-257 is equipped with a fully automatic lubrication system for the rotor-discs. The rotor-speed is adjusted with a frequency converter and therefore, can be adjusted to every specific need on the job.
The machine has an emergency button which stops the turning of the rotor and closes the main valve of the air supply.
With a weight of just 750 kg and compact measurements, the AL- 257 fits on every site, is easy to handle around and adjusts itself to every application. With a huge spectrum of conveying capacity from 0.7–9.6 m3/h, there is no work which could not be conducted economically. Is it for thin layer concrete renovation with the 2.5 l rotor up to slope protection of an excavation with the 12 l rotor, with the AL-257 one has always the right equipment.
The machine is equipped with rotors made of high tec aluminium and is operating with steel- on steelwear- and rotor plates. Experience has shown up to 10 times less wear on the steel plates, depending on material, output capacity, hose diameter and compressed air supply! This again leads to less standstill time and wear-cost and therefore to more economical spraying operation hand.
