As the connecting line between the subway and the airport, the Airport Express Railway has undertaken a large number of international tourist transportation tasks at the Capital International Airport. It is called the Guomen Line and operates at a speed of about 100 kilometers per hour. The Beijing-Shenyang high-speed railway Wangjing tunnel under the operation, requiring the construction accuracy to maintain a positive and negative 1 mm, the equivalent of an embroidery needle thickness.
Xu Weiqing, deputy manager of the project, introduced that the 11-meter-diameter large-diameter slurry shield is operated with such accuracy. All staff of the China Railway Tunnel Group participated in the shield construction based on the characteristics of the slurry shield construction and through the experience and theoretical calculations of past project construction. The parameters such as the mud pressure, the total thrust of the shield tunneling, the proportion of the synchronous grouting mortar, and the proportion of mud and water under the airport rapid track tunneling were detailedly designed and submitted. The data was set according to the specific parameters of the settlement rate and the surface bulge rate. From a low to high response scheme, a high-precision settlement control with a maximum settlement of 0.83 mm was accurately completed.
1.5 Ton Electric Reach Stacker
Zowell 1.5 ton reach stacker 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. They are usually battery driven and used for transportation of large goods. The electric reach stacker/truck combines the advantages of counterbalance electric forklift and stacking truck, which has the characteristics of environmental protection, energy saving, low noise, high lifting and working in limited space.
Detail features
1. Front moving function
The gantry can move forward 580cm which can reduce the turning radius of the
truck as well as ensure its running stability.
2. 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.
3. This reach truck adopts an original multifunctional handle from Frei, Germany. The operation is comfortable and the functional buttons can realize precise control.
4. Side loading and unloading of storage battery
The side door of the truck and battery cover can be opened, then the battery can
be removed from the side door. So the changing and maintenance of the storage
battery is convenient. There are optional batteries such as FAMM, GS, HOPPECKE,
Trojan.
5. Multipath valve stem control
Different valve stem has different functions such as fork lifting/descending,
fork tilting forward/backward, gantry moving forward/backward. The distribution
of valve stem is compact. The operator can carry out operation with only one
finger, realizing precise control.
6. The ZF driving unit is imported from Germany. It adopts vertical installation. It also delivers superior performance, stability, and reliability.
7. Emergency power-off switch: the power can be rapidly cut off in emergencies to ensure safety.
8. Multifunctional meter can display failure code, electric quantity and some other information. The operators can know the running condition of the truck via the meter.
