Abstract
The utility model provides a kind of dolly that can hook range variable, comprise main carriage frame, secondary trolley frame, on described main carriage frame, be connected with secondary trolley frame with attaching parts by bearing pin, main carriage frame, secondary trolley frame lower end are hung with respectively suspension hook, main carriage frame top is provided with main hoisting mechanism, main hoisting mechanism surrounding has wheel group to support, and wheel group drags auxiliary hoisting mechanism; The distance that this patent structure is simple, easy to use, be free to regulate two trolley lifting hook groups, can be suitable for different working conditions, opereating specification is large, cost-saving.
Description
Technical field
The utility model relates to crane facility field, is specifically related to a kind of dolly that can hook range variable.
Background technology
At present, conventional hoisting crane major-minor hoists suspension hook group hook apart from fixing, in the time that major-minor lifting mechanism lifts operation simultaneously, due to hanging object difference, the suspension centre needing is apart from difference, for head it off scene usually adopt double trolley or three dollies version, increase hoisting crane manufacturing cost.
Therefore, the utility model is to develop on the basis that mainly solves more than currently available technology existence deficiency.
Summary of the invention
The object of utility model is to solve above technical matters, proposes especially a kind of fitting operation convenient, solves and needs adjustable hook apart from operating mode, reaches the dolly that cost-saving object can hook range variable.
Based on above-mentioned purpose, the technical matters that the utility model solves realizes by the following technical solutions:
A kind of dolly that can hook range variable, comprise main carriage frame, secondary trolley frame, on described main carriage frame, be connected with secondary trolley frame with attaching parts by bearing pin, main carriage frame, secondary trolley frame lower end are hung with respectively suspension hook, main carriage frame top is provided with main hoisting mechanism, main hoisting mechanism surrounding has wheel group to support, and wheel group drags auxiliary hoisting mechanism.
Further, on described main carriage frame, reserve and be no less than 3 bearing pin mounting holes.
Further, on described secondary trolley frame, be reserved with 1 bearing pin mounting hole.
The beneficial effects of the utility model are, the distance that this patent structure is simple, easy to use, be free to regulate two trolley lifting hook groups can be suitable for different working conditions, opereating specification is large, cost-saving.
