Features

The newly designed and developed ZH50 multifunctional upper chassis, the chassis is widened, the hoist is built-in, the hydraulic main valve is arranged laterally, the structure is compact and stable, and the maintenance is more convenient; the cab is moved forward and the top protective cover is added, and the working surface is close; It is arranged horizontally for easy disassembly.
Imported Cummins QSM 11 EFI turbocharged engine is easy to maintain. According to different actual working conditions, the hydraulic system, negative feedback control main pump and engine power output are reasonably matched, making the engine high efficiency, adaptability and long life. , Good fuel economy.

The self-made ZU120 telescopic chassis developed and designed with compact structure and convenient telescopic disassembly: the slewing bearing made by Rothe Erde of Germany is selected for long service life.
Equipped with a built-in German imported reducer and brake, Rexroth motor, single-row rope, double winch with large diameter drum, so that the work efficiency and service life of the winch have been greatly improved.

Adopt advanced programmable PLC controller, inclinometer and correction system to ensure the quality of the groove. Large memory and high-resolution touch screen is used for real-time monitoring and display, recording and storing the excavation process and printing out.
The new mast lifting mechanism makes it more convenient to raise and lower the mast; the joints of the masts have a reinforced structural design to resist impact.

The multifunctional bucket body with adjustable weight is equipped with grab bodies and bucket heads of different weights according to different stratum and construction requirements. At the same time, bucket body slewing device and impact grab can be selected to improve the construction efficiency of different strata; 200 tons of large thrust Cylinder, trenching deeper and traversable The formation is more complex, which further improves the efficiency of trough formation.

ZU120 telescopic chassis

The ZU120 telescopic chassis designed and manufactured by the company is easy to expand and disassemble; the H beam flange cylinder is enlarged: the structural strength is significantly improved.
Range: 3450~4600mm; Track width: 800mm
Rothe erde slewing bearing

The slewing bearing supplier of the world-renowned brand is selected: the three-row roller slewing bearing from Rothe Erde, Germany, with long service life.
ZH50 upper chassis

The chassis jointly developed with Hyundai (Jiangsu) has a large space, comfortable, novel overall structure design and convenient maintenance:
The chassis is widened and the hoist is built-in;
The position of the cab is moved forward, which makes it easier for the operator to see the working surface, and it is safer to add a top protective cover;
The new structure large-capacity hydraulic oil tank has good heat dissipation, anti-pollution, external filter element, easy to replace;
The 700-liter large-capacity fuel tank can work continuously for more than 14 hours. The filter element is externally installed and easy to replace;
The main pump adopts international famous brand products with a flow rate of 2*380L/Min;
The MCV main valve is arranged longitudinally to facilitate installation and inspection of hydraulic hoses;
The counterweight is arranged horizontally for easy disassembly.
Hydraulic control system

Internationally renowned brands of products:
Rexroth, Bucher, Kawasaki, Hengli, Sun, SKF, Parker...
Single row rope, large diameter drum hoist

The large diameter and long drum make the hoist have a large rope capacity, and the wire ropes are arranged in a single layer, which greatly improves the service life of the wire rope, greatly reduces the construction cost and reduces the labor intensity.
German Zollern reducer and brake, the maximum lifting force is 35t.
Rexroth variable motor, three-speed lowering speed: 50/55/60m/min, the fastest: 76m/min.
Cab and control handle

The driving seat is adjustable for long-term sitting comfort;
