7T Hitachi ZX70-5A Crawler USED Excavators Accessories Special Device Japan Isuzu Engine Hydraulic System
Hitachi zx70-5a is a hot product of small excavator under Hitachi brand. In the municipal construction, water conservancy construction, road construction site often appear its shadow.
 
1, Power system
Hitachi zx70-5a is equipped with the original imported engine of Yangma 4tnv98, which can reach the maximum torque of 236nm at 1350rpm. This engine is equipped with a common EGR system, which effectively reduces the emission of air pollutants, and the exhaust emission meets the national third standard. In addition, the engine also uses "electronic governor" and "clutch fan", which effectively improves the fuel efficiency. The hydraulic system adopts independent rotary 3-pump hydraulic system, which has superior basic performance and high controllability.
 
2, Comfort and safety of cab
Hitachi zx70-5a adopts CRES cab which is highly praised for its comfort. The main part adopts high rigid steel pipe, which improves the overall strength of the cab. And the D-shaped cross-section frame is adopted to improve the strength of resisting external impact and further improve the safety of the cab. Under the premise of ensuring such high safety, the cab of Hitachi zx70-5a still has a wide field of vision. The back of the boom will not block the line of sight of the front window, which can clearly confirm the operation status. The interior has ample space for leg movement, the seat is made of durable leather, the seat and back can be adjusted, and the roof skylight can be opened.
 
3, Convenience of maintenance
The convenience of maintenance of a excavator is an important factor in the purchase. Hitachi zx70-5a has carried out a series of optimization design for the convenience of maintenance. The main fuel filter, fuel pre filter, oil filter, water separator and electric fuel pump are concentrated in the pump room. A grease barrel bracket is installed on the right side of the cab to facilitate daily maintenance.
There are many kinds of front-end auxiliary working devices of excavators. According to statistics, there are about 20 kinds of them to deal with various complex working conditions. However, many customers know little about them. Now let's explain some common equipment for your reference.
 
1, Crushing hammer
Crushing hammer is also known as hydraulic crusher. Crushing hammer is also known as gun head in the south. It is mainly used for mining ore and demolition of concrete.
 
2, Hydraulic shear
Hydraulic scissors, also known as hydraulic forceps, are mainly used in the demolition of buildings, and their efficiency is much higher than that of crushing hammer.
 
3, Vibrating rammer
Vibration rammer, also known as hydraulic rammer or rammer, is mainly used for water conservancy slope protection, high-speed and railway slope construction, and some small excavators are used for building foundation compaction.
 
4, Excavator accessories -- quick connector
Quick connect machine, also known as quick joint or quick change-over joint, is specially used to switch the crushing hammer (or other equipment) and the digging bucket. Generally, skilled operators can switch equipment in no more than 30 seconds. In the past, it took 40 to 60 minutes and more than two people to operate.
 
5, Scarifier
Scarifier, also known as Ripper, is mainly used for weathered stone construction. It is easy to use when working in layers. It is hard to dig the bucket, and it is a little easy to waste when breaking the hammer. At this time, the use of scarifier will greatly improve the construction efficiency. First, use the scarifier to separate the soil layer or weathered stone layer, and then use the quick connector to switch the bucket for loading.
 
6, Wood Grabber
Wood grabber, also known as wood clamping machine, is divided into hydraulic grabber and mechanical grabber. Hydraulic grabber is also divided into hydraulic rotary grabber and fixed grabber. After redesigning and modifying the claws, the wood grabber can be used to grab stones and scrap steel. It is mainly used to grab wood and bamboo. Loading and unloading vehicles are very fast and convenient.
 
7, Hydraulic rock drill
Hydraulic rock drill, also known as drilling machine, is mainly used in mine blast hole construction.
