Counterbalanced fork-lift trucks -
Testing method for whole machines
1 Scope
This Standard specifies the test method for whole machines of the
counterbalanced fork-lift trucks’ preparations before test, test conditions,
parameter determination and stability, loading and unloading performance,
steering performance, operating performance, dynamic performance, energy
consumption, braking performance, vibration, noise, etc.
This Standard is applicable to the internal combustion counterbalanced fork-lift
trucks with the rated lifting capacity of 500kg ~ 10,000kg (referred to as “internal
combustion fork-lift trucks” in particular to the internal combustion
counterbalanced fork-lift trucks) and the battery-powered counterbalanced fork-
lift trucks with the rated lifting capacity of 500kg ~ 5,000kg (referred to as
“battery-powered fork-lift trucks” in particular to the battery-powered
counterbalanced fork-lift trucks), which are hereinafter referred to as “fork-lift
trucks”. Other types of fork-lift trucks can use this Standard for reference.
2 Normative references
The provisions in the following documents become the provisions of this
Standard through reference in this Standard. For dated references, the
subsequent amendments (excluding corrections) or revisions do not apply to
this Standard. However, parties who reach an agreement based on this
Standard are encouraged to study if the latest editions of these documents are
applicable. For undated references, the latest editions apply to this Standard.

and the condition of mast tilting backward to the greatest extent.
c) Standard load status. The fork-lift trucks shall be equipped with test loads.
The masts shall be vertical. The upper surfaces of the forks shall be 300mm
away from the ground.
d) Standard load operating status. OPERATE under standard load status and
the condition of mast tilting backward to the greatest extent.
4 Preparations before test
4.1 Purpose of the preparations
Before the test, the fork-lift trucks shall have normal technical status, so as to
ensure the correctness of the test results. In the meanwhile, ELIMINATE
various hidden dangers to ensure the security and the smooth conduct of the
test, and to avoid accidents.
4.2 Work items
4.2.1 Test forklift acceptance
4.2.1.1 REGISTER the product certificate, manufacturing plant’s name,
product model, product serial number or manufacturing date, and the original
dimensions of the parts that need to be dismantled and inspected.
4.2.1.2 CHECK the integrity of the fork-lift trucks’ assemblies, components,
accessories, accessory devices and attached tools, tightening degree of the
fasteners in key positions, lubrication and sealing conditions of the assemblies’
lubricating oil and points, sealing conditions of the hydraulic systems and oil
pipe connectors, insulation resistance between batteries and bodies of the
battery-powered fork-lift trucks, and firmness of the battery cells in the
containers, battery containers in the frames and battery system wiring.
4.2.1.3 CHECK the assembly condition of the fork-lift trucks. For the fork-lift
trucks in standard no-load operating status, CHECK whether the steering
system, transmission system, braking system, operating system, electrical
system and battery container sets are normal and reliable. For the fork-lift trucks
in standard no-load status, CHECK whether the mast lifting system and
hydraulic system are normal and reliable. There shall be no oil leakage.
4.2.1.4 CHECK whether the nameplates and load curve plates of the fork-lift
trucks are correct, and whether their security identifications are integral.
4.2.2 Forklift running-in
5.5 Before the performance test, fully PREHEAT the fork-lift trucks.
5.6 During the test, CONFORM to the following conditions.
a) The ambient temperature shall be with...
