Description

The 2Л1200 is a heavy-duty belt conveyor with a 1,200 mm belt width, designed and manufactured by LLC Makeevsky Zavod Lazer, a Russian industrial machinery plant with deep roots in the coal-mining sector. Established on the site of a former mine in Makeevka in 1968 and reorganized as Zavod Lazer in 1995, the company concentrates its output on mining and processing equipment for the coal industry.

Its 250-strong workforce operates across more than 24,000 sq.m of production space equipped with over 300 machine tools, enabling a complete in-house production cycle from casting and heat treatment through precision machining to final assembly and quality inspection.

The 2Л1200 is configured with one or two independent drive units, each rated at up to 160 kW, moving material on a 1,200 mm belt at speeds selectable between 1.0 and 5.0 m/s. Corresponding throughput ranges from 9.8 m³/min at the lowest speed to 49.5 m³/min at the highest, meeting the demands of continuous coal transport along gate roads and main haulage entries.

The 1,400 mm drum shell length reduces peak belt tension and extends belt service life. The conveyor operates across inclination angles from −10° to +18°, covering the typical geometry of underground development headings and panel haulage layouts.

Standard configurations span 30 to 500 m in length, with longer custom builds produced to order.

Details & Equipment

Drive System Components

Head Drive Drums

Rubber-lagged drive drums manufactured for 1,200 mm belt conveyors at the Makeevka plant. The 2Л1200's 1,400 mm drum shell width reduces peak belt tension and extends belt service life under continuous underground coal duty.

Cylindrical Gear Reducer

Finished and painted cylindrical gear reducer as used in the 2Л1200 drive station, providing the precise speed reduction needed to deliver belt speeds from 1.0 to 5.0 m/s from the 160 kW drive motor.

Technical Specification Sheets

Performance Data — Multi-Drive Configuration

Manufacturer's specification table for the 2Л1200 in 2–4 drive-unit configuration. Covers belt width 1,200 mm, capacity up to 49.5 m³/min, 2 × 160 kW max drive power, and inclination range −16° to +18°.

Performance Data — Single/Dual Drive Configuration

Standalone specification sheet for the 2Л1200 with one or two drive units. Belt width 1,200 mm, drum shell 1,400 mm, delivery lengths 30–500 m standard, operating inclination −10° to +18°.

Features

📏

1,200 mm Belt Width

The 1,200 mm nominal belt width delivers throughput from 9.8 m³/min at 1.0 m/s up to 49.5 m³/min at 5.0 m/s, suited for continuous high-volume underground coal transport.

⚡

Dual 160 kW Drive Units

Two independent drive units supply up to 2 × 160 kW total, providing redundancy and smooth torque distribution along the full conveyor length.

🔧

Wide Speed Range

Belt speed is selectable across eight steps — 1.0, 1.6, 2.0, 2.5, 3.15, 4.0, 4.5 and 5.0 m/s — allowing output to be matched to current face production rates with ±10% tolerance.

📐

−10° to +18° Operating Angle

The standard inclination range covers the majority of underground gate road and main haulage entry geometries without special structural modifications.

⚙️

1,400 mm Drum Shell

The wide drum shell distributes belt contact load over a larger surface, reducing tension-induced wear and extending belt service life in continuous underground duty.

🏭

Full In-House Manufacturing

Drums, gearboxes, frames, rollers and drive couplings are all produced at the Makeevka plant under a complete cycle — from incoming material control through machining to finished product inspection.

Buyer Benefits

Throughput up to 49.5 m³/min on a single conveyor reduces the number of transfer points required in main mine haulage systems
Two independent drive stations allow the conveyor to operate at reduced capacity if one drive requires maintenance, avoiding a full production stop
Eight selectable belt speeds let operators match conveyor output directly to face advance rate, reducing unnecessary wear at light loads
Inclination tolerance of −10° to +18° means the same model covers development headings, gate roads and drift conveying without re-engineering
Custom delivery lengths beyond the standard 30–500 m range are manufactured to order, eliminating unnecessary intermediate transfer stations
All major wear and drive components are produced in-house, simplifying spare-parts supply and reducing lead times for replacements
Direct factory supply from Zavod Lazer removes intermediary markups and supports long-term maintenance contracts backed by the manufacturer

Applications

Longwall gate road coal transport in underground coal mines Main haulage drift conveying systems linking panels to the shaft bottom Panel entry transport moving run-of-mine coal from face to central haulage roadways Multi-stage relay conveyor systems on long underground haulage routes Underground incline and decline haulage on moderate-gradient headings Feeder conveyors supplying underground coal preparation or sizing plants Surface stockpile loading and transfer at coal preparation facilities Tunnel construction material and spoil transport during shaft sinking or development
