Aliva 257 Shotcrete Spraying Machine
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
- 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.
