Abstract

Belonging to the construction machinery field, an embodiment of the invention provides start-up control equipment and method for construction machinery and the construction machinery. The control equipment can be a control circuit, the control circuit includes a first relay and a first switch, one end of the first relay is coupled to the upper potential of the construction machinery, and the otherend of the first relay is coupled to a power supply negative pole, a first normally open contact of the first relay is in series connection with the first relay, and a second normally open contact ofthe first relay is in series connection with an equipment start-up circuit of the construction machinery. The first switch is in series connection with the first relay and is in parallel connection with the first normally open contact, and when an alarm device of the construction machinery starts up, the first switch is turned on. Therefore, the construction machinery just can be started up onlyafter the alarm device is started, and the damage possibly caused by the construction machinery during work to surrounding people is reduced.

Description

technical field [0001] The present invention relates to the field of construction machinery, in particular to a start-up control device and method for construction machinery and construction machinery. Background technique [0002] The operating conditions of construction machinery are harsh and complicated, and personnel are required to assist around during equipment construction. Therefore, there are certain safety risks for surrounding personnel during construction of construction machinery. Construction machinery is generally equipped with an audible and visual alarm device to attract the attention of the surrounding personnel. At the same time, the operating procedures also require the operator or driver to activate the alarm device to warn the surrounding personnel before starting the equipment. [0003] The inventor of the present application discovered during the implementation of the above-mentioned prior art that the operator can also directly start the constructio...
