(54)	A machine for pile-driving, a method for transport and erection of a machine for piledriving, and a method for establishement of foundations beside rails

(57) A machine for pile-driving comprises a driving chassis with wheels (5,6) for moving on railway or road, and an upper part (4) pivotally mounted about a swivel axis on the driving chassis. A mast (215) with slide guide for a ram mechanism (16) is connected to the upper part. The mast may be erected to substantially vertical position for the purpose of pile-driving and may be lowered into substantially horizontal position for the purpose of transport.
According to the invention the mast is connected to the upper part of the machine by a telescopically extensible and contractible boom having a base part (228) being connected to the upper part of the machine by means of a hinge with axis at right angles to the swivel axis of the upper part, and a telescopically extensible part (229) connected to the base part, said part (229) being connected to the mast by a slide guide so that it is movable along the longitudinal axis of the mast retaining the angle between the axis of the mast and the extension axis of the boom. A very simple erection and dismantling of the mast is hereby achieved as well as the possibility of swivelling said mast through 180° when the machine is standing on one half of a double track, without the mast thereby getting in the way of traffic on the neighbour track.
The invention also relates to a method for transport and erection of such a machine and a method for placing of foundations next to a railway track.
