Abstract

The invention relates to the technical field of engineering machinery, and discloses a control method for a crane, a processor, a control device and the crane. The crane comprises a boom. The control method comprises the following steps: receiving a lifting instruction of the boom; determining whether the crane meets a preset condition; under the condition of determining that the crane meets the preset condition, acquiring the rotation angle of the boom; a first mapping relation between the rotation angle and the safe lifting angle of the boom is obtained; according to the rotation angle and a first mapping relation, a safe lifting angle corresponding to the rotation angle is determined; and the lifting angle of the arm support is limited below the safe lifting angle. According to the present rotation angle of the boom, the lifting angle of the boom is limited below the corresponding safe lifting angle, so that the backward overturning danger caused by too high lifting of the boom is avoided, the economic loss and casualties caused by backward overturning are avoided, and the operation safety of the boom of the crane is ensured.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a control method, a processor, a control device and a crane for a crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. When engineering equipment such as cranes are operating, if the operator does not operate properly, such as raising the boom too high, it may cause the danger of overturning. When the crane overturns after an accident, it may damage the equipment and cause economic losses; it may also hit the staff and threaten the safety of personnel. [0003] For example, for a certain type of crawler telescopic crane, if the boom is raised above 70 degrees without the track frame being extended, there may be a danger of rear tipping. For another example, for a certain type of off-road tire crane, if the boom is raised above 70 degrees under the...
