The rail of the weighing-machine is long 3.6 meters。

Two-way automatic bogie dynamic weighing method for measuring, even hanging dynamic metering or not even hang humping dynamic measurement。

Train measurement speed range:3kmh TO 18kmh，(Not measured by weighing apparatus maximum speed：25kmh

Error margin and accuracy：

Match the nation examination rules JJG234-2012 Automatic rail-weighbridges of correspond the item.

a、（Accuracy of automatic rail weighbridge is divided into four

     levels: 0.2, 0.5, level 1 and level 2。My company's

    automatic rail weighbridge usually adopt level 1）

 b、(Permissible error table)：

c、(Accuracy)

Equipment increase or decrease the 20 kg weight, value should be not less than 10 kg of change。

The total power consume：ABOVE 500W

(The work condition)：

(Measurement of the vehicle must conform to the requirements of the railway，weight is more than 18 t and less than 100 t（special circumstances can reach 150 t），track width is 1435 mm axles truck)

(The machine part installs in the pit ,The equipments pit both ends should have the certain long straight and even orbit.)

（Sensor normal work temperature）：0C---60C。

The environment of the Calculate building is at the request of match the usage of the Computer.）

（Power voltage）：220V±10%，50±2HZ。

(The equipments keeps off the strong electromagnetism interference, keeping off the erodent gas.)

(The control room has to connecting a ground goodly, electric resistance small in 4Ω.)

(The product constitute and structure characteristics)

(This product is from the machine part, weigh Sensor and weigh the displaying instrument, printer composing. Each part of main function and characteristicses are as follows.)

4-1 Machine part)

(The machine part is use to load the vehicle，the machine part from main beam，weigh sensor to link up the system，a system of horizontal limit，lengthways Limit，the protection cover plank etc. constitute( see the diagram)。)

(The main beam uses profiled bar welding ，it cuts to face trunk，having the enough strength。Build the steel rail on the main beam，provide to load the vehicle to go through。)

(The machine part passes to Sensor link up to equip from Sensor prop up，adjust the conjunction device makes weigh sensor to keep the verticality，the assurance is whole to weigh the realization of the accuracy。)

 The stability of the system composed of vertical and horizontal two limit system，one end of the protection device is fixed on the main girder，at the other end is fixed on the frame。Through the adjustable nut，also can adjust the track width and the size of the rail gap.

 The iron cover plank of the machine equipments has the protection function.

 Weigh Sensor Part

 Weighing sensor is a key part of the weighing system，this device adopts digital sensors，has the features of high precision and good technical performance，for the weighing accuracy of the whole system has played a important role in guarantee.

 The machine install, adjust，breakdown maintenance.

 The machine  Install

 The work condition of the machine gearing and prepare the work.

 The pit of the machine equipments，both ends foundation，the control room completion of work，and through check each part meets the homologous technique provision。Having nothing to do with equipments the sundries already clearance.

 The basal both ends has already had the condition of build the rail.

 The power supply of the spot has already connect.

 Theproduct that examination delivers the spot packs the piece and packs well-found and intact， have no damage.

 The crane equipments( load 30t) and worker has already ready to 

 The electric welding machine，solderer ready to 

Install the machine and link up the system.

According to the request adjustment steel rail elevation、gauge、rail clearance of the technique document and the diagram paper.

 The adjustment sensor to link up the system，make sensor perpendicularity in the horizontal plane，sensor with armor plate adjustment height，make each sensor even be subjected to the strength.

 Adjust the vertical and horizontal limit system according to the technical requirement

 The adjustment pulls the pole to link up the position，tight nut

 Install to control the instrument

 Sensor line connects to go in junction box，the total cable wear into the steel pipe to lead into the control room to combine with the instrument of correspond the plug welding。）

b.Install the instrument，the computer software，the instrument connects the ground。）

c、（Check each part after install without any error then connect the power，prepare to adjust。）

(The equipments adjusts to try

(Adjust the work condition for try and prepare the work

(The machine part and sensor to link up the system to have already install to complete

(The weight manifestation controls the instrument to have already install to complete

(The orbit circuit has already spread good，and connect all )

（Prepare five carriages，four vehicles load carriage，an empty carriage ）

Repeatability and direction error of debugging）

（Locomotive traction five carriages，again and again through the device，Record every time weighing data, compared to the same direction data repeatability, different direction data error value, and then adjust, make the adjustment direction of the same data error to a minimum, different direction of the data error adjustment to a minimum。)

(The maintenance maintain)

(The machine maintenance)

(The periodical check steel rail elevation、gauge、track sew medium whether be placed in the normal appearance，there is excrescent circumstance，please adjust in time。)

(Periodical the check limits and each conjunctions part，keep screw from loosen to move。)

(Automatic rail weighbridge of buildingprojects)

(The foundation construction at the request of press relevant technique and the equipments install to request to carry on，the equipments pit presses manufactory the size and the technique conditions for provides to construct)

(The Automatic rail weighbridge covers the size as follows diagram):
