Unloading carriage board is not installed, and the compartment floor surface 1m above the ground, you should install a similar escalator. At the top of the escalator should be set to one or more

armrest.

If the trailer carriage plate relative to the height of the bottom surface is greater than 900mm, should be required to install 4.6 GB 10395.1-2009 in

Within the escalator. Within the escalator should be outside escalators installed in the same car at the plate, and the outer escalator opposite.

Note. The right side of the escalator should be installed as the forward direction of the trailer.

4.4 dump

4.4.1 In the driving position should always be able to operate the dump operating mechanism (lifting or lowering).

If the subsidiary operating mechanism is equipped with the trailer, the control mechanism should continue these manipulative, and should be consistent with GB 10395.1-2009

6.1 requirements.

4.4.2 hydraulic dump system and hydraulic brake systems should not be controlled by the same hydraulic line.

4.4.3 trailer in the structure should be limited to no more than the maximum allowed car dumping position.

Stability Test (backward dump trailer)

B.1 Scope

This appendix applies only after the dump trailer. This annex does not apply to the high side dump trailers and dump trailers.

B.2 Test Equipment

--- Test platform. a side of the axis of rotation of the tiltable platform. Platform surfaces should be smooth, solid, quality, and able to withstand the trailer

No effect on the test results of deformation.

--- Plate. thickness 1mm, length and width of the tire beyond the proper indentation plate.

--- Load measuring devices. measuring drawbar tractor or mechanical coupling system between the bracket vertical load devices.

--- Prevent tilting during the trailer fully test the device.

B.3 Test Procedure

Trailer should be a standard test configuration, loaded up the car plate. The trailer shall be equipped with a minimum width specified by the manufacturer, the corresponding maximum wheel diameter

Tire, tread should be set to the narrowest. Tire inflation pressure shall be specified by the manufacturer.

Installation preventing tilting during the trailer test device, it can not affect the test results.

In the following manner to trailer load. at M compartment floor before applying equal to 1/4 of the maximum permissible load 1/4 (Q/4) in force, as

B.1 and B.2 below. M point is half the height of the compartment, the bearer plane (S) of the center of gravity above.

The trailer is placed on a test platform, uphill each tire placed a steel plate below. Plate should extend beyond the sides of the indentation. On Tractor

Car, tow bar should remain on high position specified by the manufacturer, or on his tractor with a similar connection with mechanical support device is fixed in the flat

Table, or a tractor mounted (tractor has stopped on the platform). The steering wheel should be in the straight-ahead position.

Figure B.2, tilt test platform to slope 5 °.

Slowly and steadily lift (dump) compartment to the highest position.

Vertical load measuring mechanical coupling system.

B.4 Test acceptance

During the test, at least one uphill tire remains in contact with the table.

When using the 50N force the tire can not be extracted from the side of the steel plate under it is a contact surface.

During the test, the mechanical coupling system should be no vertical upward load.
