The ZDL203 underground loader is a trackless shovel loading and short distance transportation equipment designed and manufactured specifically for underground mines

Product Details

Mainly used in conjunction with mining trucks in underground excavation and mining operations. Shovel loading of ore and various materials can greatly improve operational efficiency and is an important equipment for achieving trackless mining. The ZDL203 underground loader is powered by a diesel engine, with hydraulic mechanical transmission, four-wheel drive, lateral driving, central articulated hydraulic steering, large steering angle, flexible turning, and small radius. It is suitable for medium section tunnel operations and has the following technical characteristics: ●The power system adopts a Deutz air-cooled engine; ●The power transmission system adopts a gearbox and torque converter, domestically produced spring brake hydraulic release drive axle, and mining cut resistant pneumatic tires; ● The driving brake adopts a wet multi disc spring brake hydraulic release brake; Filling valve and brake valve; The parking brake adopts a spring brake on the drive axle for braking; ●The frame is a centrally hinged structure, with the rear axle swinging left and right around the center of the frame to improve the overall adhesion performance of the vehicle; ● Hydraulic power steering system with a single steering cylinder for the steering system; Safety Alert ●The operator of this machine must wear a safety helmet and carry a self rescue device and a mining lamp with them when entering the well; ●This machine must be regularly maintained and inspected, and any hidden dangers should be promptly addressed; ●It is strictly prohibited to conduct maintenance while the machine is in operation; ●When the machine is undergoing maintenance, the power must be cut off and the words “under maintenance, no starting” must be hung; ●When conducting maintenance under the raised boom, the boom must have firm and reliable support; ●When entering the machine for welding and cutting, safety measures must be taken after confirming that there are no flammable or explosive materials present Only with full measures can operations be carried out; ●When the engine is running and the exhaust pipe has not cooled down after shutdown, it is strictly prohibited to have physical contact with the muffler ●The surface of the exhaust pipe to avoid serious injuries such as burns; ●When repairing the hydraulic system of this machine, the pressure must be completely relieved before starting the operation. Usage conditions: 1) This machine is suitable for use in tunnels with a cross-sectional size of 2.5 meters (height) × In tunnels of 2.5 meters (width) and above The homework requires a firm top plate, a minimum turning radius of ≥ 4.3 m on the outside, and a road slope of ≤ 14 °, Good ventilation and drainage in the workplace; 2) The ambient temperature of the tunnel is -5 ℃ to 40 ℃, and the maximum relative humidity is not more than 85% (temperature at 25 ℃) Time); 3) The altitude of the usage location shall not exceed 1000 meters, and in the Gao Yuan Huan area with an altitude exceeding 1000 meters Power reduction is required for use in the environment; 4) The sulfur content of the fuel used in this machine shall not exceed 0.2%; 5) This machine is strictly prohibited from being used in places with flammable and explosive gases such as gas and coal dust;
