Description

Fork truck counter weight device of adjustable load centre-to-centre spacing Technical Field The invention belongs to the technical field of forklift counterweight, and particularly relates to a forklift counterweight device capable of adjusting load center distance. Background The balanced heavy forklift is widely applied in the fields of storage, logistics, factories and the like, the load center of the balanced heavy forklift is between 50% and 55% of the whole vehicle wheelbase in an empty load state, the middle part of the center of gravity of the whole vehicle is deviated, and the original weight at the tail part is used as a core stabilizing component, so that the balanced heavy forklift has the main effects of increasing overturning moment and guaranteeing the operation stability of the whole vehicle. Along with the diversification of operation demands, part of users can reform the tail part of the balanced forklift so as to expand the functional application scene of the balanced forklift. In the prior art, the condition that the original counterweight only bears the function of increasing the overturning moment is replaced by a working mechanism with a special function exists, and when the working mechanism works under the condition, the gravity center of the whole forklift is seriously and backwardly deviated, so that the working performance of the tail working device is greatly limited, the special function of the tail working device cannot be fully exerted, the original balance state of the whole forklift is seriously damaged, the stability of the whole forklift is obviously deteriorated, potential safety hazards such as rollover are easily caused, the operation safety and the efficiency are influenced, and in summary, a forklift counterweight device with the adjustable load center distance is needed.
