Engineering ladder for mounting electromechanical equipment in building construction

The utility model belongs to the technical field of building construction, in particular to an engineering ladder for mounting electromechanical equipment in building construction, which comprises a first ladder and a second ladder, the front of the second ladder is slidably connected with the back of the first ladder, and clamping holes are equidistantly formed in two side walls of the second ladder. Limiting mechanisms used for clamping the clamping holes are installed on the two side walls of the first escalator. The first escalator and the second escalator are connected in a sliding mode, the clamping holes are formed in the second escalator at equal intervals, the limiting mechanism used for clamping the clamping holes is arranged on the first escalator, and therefore the overall length can be adjusted conveniently and rapidly, when transportation is needed, the second escalator can be retracted downwards, and transportation is convenient. Therefore, the overall length can be shortened, transportation is
