Jin top 14 or common electricity hydraulic jack 15 and control device composition.
Wherein, mobile steelframe, dolly and motor, counterweight composition horizontal loading position adjustment system.Fixed steelframe with
And gap and jack fixing hole constitute vertical loading position adjustment system between H profile steel contained by removable steelframe.
Base girder, base secondary beam and base cladding plate constitute the base of loader.Base cladding plate is provided with trolley track, small
Car can be moved back and forth along the track.Trolley track is made up of two one steel rails, is position line between rail.Fixed steelframe is fixed on bottom
On seat cladding plate, the first bracing members provide support for fixed steelframe, prevent it from toppling over.Mobile steelframe is located on dolly, and is reliably connected
Connect.Motor and counterweight displacement dolly afterbody, motor provide power for dolly, and counterweight prevents removable steelframe from toppling.It is hollow
Electric hydraulic jack and common electricity hydraulic jack can be fixed on fixed steelframe and removable steelframe.
With reference to Fig. 3, in a case study on implementation, fixed steelframe 1 and removable steelframe 3 are by two HW250X250-
HW300X300 shaped steel is constituted, shaped steel spacing 60mm, and two row's jack fixing holes, spacing 200mm, and every holes are left in inner side
Between throat thickness be 10-12mm thickness ribbed stiffener.Above-mentioned fixed steelframe 1 is welded with base cladding plate 7.First bracing members and the second steel branch
