Product Description

Introduction

Crawler-belt mucking loader ZWY-80 is mainly used for cave mining operations with narrow spaces, such as metal mines, water diversion roadways, etc. Its function is to collect gravel and slag materials for various projects, it transports and loads them into other vehicles. The machine relies on the crawler to push and shovel rocks, and the rocks are picked up by the bucket into its own belt conveyor. The conveyor unloads the rocks from the tail into dump trucks, mine cars or other loading equipment. At the same time, the backhoe digging arm can also be used to pick up rocks within the distance , and the bucket can also be used to clean the working face.

It is suitable for roadways with a cross-section of 2.5×2.5 meters or more. The whole machine is crawler-tracked and belt-conveyed. It is suitable for mining and operations working faces with slopes within 15 degrees. One machine can replace multiple manual workers.

Technical Parameter

1.Walking System: The use of Shantui crawler tracks guarantees quality, and the slope is about 10-15 degrees, which reduces the hidden danger that the tire might be unstable when there is water on the working face with slopes of 10-15 degrees and also the weakness of the tire itself that is not conducive enough to climbing in case of the easily damaged flaws on slopes.

2.Hydraulic Pump: The military pump is selected, which is strong in wear resistance and pollution resistance, high in efficiency and long in service life.

3.Hydraulic Motor: Yining hydraulic motor is selected, and the track can walk freely at about 10-15 degrees with good safety and stability.

4.Conveyor System: The belt is a one with no protruding heads. It has been verified that there is no problem with fine materials and slag on slopes of about 8-15 degrees. It is very practical and solves the problem of walking safety with slopes of certain degrees.

Easy and Flexible Hydraulic Pilot Operating System

This model adopts a hydraulic pilot operation valve design. Compared with the joystick operation method, this operating system is easier, more flexible, and reduces fatigue of the arms. The operator can also save a lot of physical strength.

Applicable type for Slopes and Mines

1. Suitable for 8-15 degrees.

2. Applicable to the tunneling roadways in mines for gold, coal, lead-zinc, copper, aluminum and other metals.

3. Suitable for working spaces about 2.5*2.4 meters.

Manufacturing Process

1. Annealing treatment: After the structural parts are processed, they are tempered at a high temperature of 650c to eliminate their internal stress, so as to improve the torsion resistance and to ensure the stability of the structural parts.

Zhongliang has modern manufacturing equipment, such as the machine for milling, boring,, as well as the CNC lathe, and the ones for radial drilling, shearing, bending, flame cutting and other high-tech advanced large-scale manufacturing equipment.

The gantry frame uses 30 thick steel plates from WISCO for the supporting points; 12 thick steel plates are used on both sides of the gantry frame to ensure the stability of the structural parts.

2. Shot blasting treatment of structural parts: After all the structural parts of Zhongliang Machinery are welded, the surface of the workpiece is strengthened by the treatment of shot blasting machine, the fatigue resistance of the product is improved, the stress concentration is eliminated, and the adhesion of the paint to the structural parts is increased.

Foldable Conveyor Rack

Small mines have small working surfaces and many curves. The disadvantage of large equipment is that the movement for transferring remains unchanged, and some large equipment cannot enter the operation site at all. This car adopts a rear folding design, which can be folded down by 1 meter when there is a curve, which shortens the length of the whole machine.

Hydraulic Drum

At present, the conveying system of the mucking loaders in the market is dominated by electric drums, and the voltage instability in underground mines might lead to the burning of electric drums. Zhongliang uses a hydraulic drum as the power, which has so far been verified, and it reduces the influence of voltage instability in mines on the mucking loader.
