The appliance for pile driving-in has two installed with possibility of displacement along rails beam-trolleys equipped with drives of that displacement with fixation of the positions of those in the places of the piles drive-in, and rigidly connected to each other with transverse main and supplementary beams placed with a gap between those, vertical stand with mechanism for pile drive-in, movable support of the stand installed on the transverse beams with possibility of displacement along those and equipped with drive of that displacement, and counter-weights. At that the movable support of the stand is arranged as two placed under the transverse beams long beams; on the front ends of those, in front of the main beam, a vertical stand is fixed, the beam-trolleys are arranged with prominent forward sections, and the counter-weights comprise of three groups, one of those is placed on the beam-trolleys between the main and the supplementary beams, and two others - in front of the stand, with a gap between those at the prominent sections of the beam-trolleys. Each of the long beams is equipped with ?-like cramp fixed at its opposite stand, this is formed by the upper horizontal shelf and two vertical walls with formation of a passage through which the supplementary transverse beam goes between this one and the upper surface of the long beam.
