Natural Copper (Copper)

[Chemical composition] Cu native natural copper often contains a small amount of Au (up to 2% to 3%), Ag (up to 3% to 4%), Fe (up to 2% to 3%) and other mixed substances. The chemical composition of secondary natural copper is relatively pure.

[crystal structure] equiaxed crystal system; , with a copper structure (Fig. Z-1); a ₀ = 0.361 nm; Z = 4.

Figure Z-1 Copper crystal structure

[Form] It is usually an irregular dendritic, flaky or dense block assembly. When a single crystal appears, a cube {100}, an octahedron {111}, a rhombohedron {110}, or a tetrahedron {410} can be seen. But natural copper crystals are rare. It can be double crystal according to (111).

[Physical properties] copper-red color, often due to surface oxidation occurs Qiang color brown; streak copper-red color; metallic luster, opacity. No cleavage; the fracture is jagged. Hardness 2.5 to 3. The relative density is 8.95 (pure copper). It is malleable. The temperature of 1083 ° C. A good conductor for heat and electricity.

[Genesis and occurrence] Natural copper is common in the original hydrothermal deposit, the lower part of the oxidized zone of copper-bearing sulphide deposits and the sandstone copper deposit. It is the product of reducing conditions under various geological processes.

Natural copper is unstable in the surface and oxidizing environment, and is easily oxidized into oxides and carbonates, such as ore, malachite, azurite and other minerals.

[Identification features] Copper red, the surface oxide film is brownish black, strong ductility, and relatively high density.

[Main use] It can be used as copper ore mining when the amount of accumulation is large.

2 ton sitting on electric reach truck

Zowell FRB20 model sitting on Electric Reach Truck is standard with side shift function. It is an industrial material handling equipment, which refers to the forward moving wheel type vehicle which carries out loading and unloading, stacking and short distance transportation of the good by pallets.

There are also many options like camera and monitor, EPS function, AGV modification, height preselection function etc. The sitting on electric reach truck is a high performance truck with perfect performance and excellent safety.

What's more, it is equipped with intelligent system, American Curtis controller system, double AC system ensure its flexible operation in the big warehouse.

Detail features

1. Wider area for the leg
The legroom of the operating position is ample, allowing the operator to move flexibly. They will feel comfortable without worrying about being cramped.

2. Sitting type operation
The seat is adjustable. The soft seat can relieve fatigue and provide a safe and comfortable driving experience for operators.

3. Design of low center of gravity
The design of low center of gravity can ensure stability of the truck so that it is anti-overturning even in complex working conditions.

4. height-limited lifting

5. Turning speed limiting device
The precise high speed limiting turning control technology can prevent side overturning, thus protecting the goods from dropping.

6. Good lifting ability
The max lifting height is 9000mm which can meet the requirements of goods stacking in certain height.

7. Front moving function
The fork can move forward for 590cm,which can reduce turning radius of the truck as well as ensure running stability.

8. Small turning radius

This reach truck has a small turning radius which is only 1700mm. It can move flexibly even in very tight warehouse and workshop areas.

9. Tilt forward and backward

The fork can tilt forward and backward for easy loading and unloading of goods and material, thus improving the transporting stability of the reach truck.

10. Forged fork
The width of the fork can be adjusted within the range of 200-760mm. It is suitable for working conditions with both single side pallets and double side pallets.
