1 Scope
This standard specifies testing method for whole machines of counterbalanced fork-lift truck in terms of pre-test preparation, test conditions, parameter determination and stability, handling performance, steering performance, traveling performance, dynamic performance, energy consumption, braking performance, vibration and noise.
This standard is applicable to diesel type counterbalanced fork-lift truck with 500kg ~10000kg rated capacity (for diesel type counterbalanced fork-lift truck, "diesel fork-lift truck" for short) and battery counterbalanced fork-lift truck with 500kg ~5000kg rated capacity (for battery counterbalanced fork-lift truck, "battery fork-lift truck" for short); and it is also used as a reference for other types of "fork-lift trucks".
