(2) At the initial stage, the counterweight anchoring rods must drop down under its
own weight, and it must be aligned with the mounting hole of counterweight base
plate. Do not pull the anchoring rods diagonally, otherwise accidents will occur. If
the counterweight plates at left and right sides of crane is not level during lifting,
put counterweight down on the ground, check if the counterweight plates are
stacked neatly, and then adjust lifting position of counterweight by moving crane
forwards and backwards.
(3) The counterweight lifting cylinder must be operated slowly and smoothly during
lifting of counterweight. When the counterweight is lifted to required position, check
if the counterweight lifting cylinder is aligned with the hole on the counterweight
base plate, thus avoiding damaging the cylinder.
(4) In any cases, the assembly and dismantling of counterweight must be performed by
at least two persons.
(5) The counterweight self-assembly & dismantling mechanism is only used for the
assembly and dismantling of counterweight. It can not be used to lift other objects.
Otherwise, the accident may occur.
(6) The dismantling of counterweight is carried out in reverse order of assembly.
