Technical Specifications:
The document provides detailed specifications for the SL/SLA series of concrete mixers. Key parameters include geometric volume, filling ratio, water line capacity, rotation speed, drum diameter, and water pump output. The mixers are designed with varying capacities ranging from 4 to 15 cubic meters.

Drum and Blades:
The drum is constructed from high-resistant steel (30MnB5) with a thickness of 4 mm, designed to meet international specifications and DIN 459 standards. An optional upgrade to 450 HB steel is available for enhanced wear resistance.

Standard Equipment:
Includes two rollers with off-road support, washing nozzles, a manometer, additional chutes, a hydraulically driven discharging chute, and a water pump driven by a reducer. The mixers also feature an oil cooler, plastic back protection, and a polymer mono-axle mudguard.

Control Systems:
The mixers are equipped with a control system for both "BASIC" and "CSD Advanced" versions. The system allows operation from both inside and outside the cab, providing information on drum speed, hydraulic pressure, and diagnostics.

Optional Features:
Options include a hydraulic water pump, aluminum pressurized water tank, centralized roller greasing system, and an automatic opening system for the loading hopper. Multi-color customized painting is available on demand.

Design and Maintenance:
The SL/SLA series is designed for modern, compact performance with a focus on safety and ease of maintenance. The mixers are sandblasted and painted for rust prevention, with zinc protection on ladders and chutes.
