The present invention is to combine the trolley (trolley) to the T-type crane which model is selected according to the surrounding environment of the construction site for the construction of new buildings, such as apartments (T-type tower crane) or L-type cranes (luffing type tower crane) so that you can use,
One T-type crane and the roughing type crane Combine trolley according to an embodiment of the invention, the mast and the counter jib pivotably mounted at the top of the mast, and a jib which one end is fixed to the counter jib, the top of the mast mounted and the jib and the counter jib, and one end is fixed to the upper tower and the upper tower for supporting and is fixed the other end to the front side of the jib is fixed to the jib seoseupensyeonwa, the counter jib for supporting the jib the jib weight according to the weight lift center and a counter weight balancing for the mobile, the counter jib mounted on the by lifting the hook by a hoist wire for being wound on the winch is attached to the hoist winch to the vertical lifting the weight, on the counter jib wound on winch wound on the luffing winch, the winch mounted on the jib for pivoting the jib by the multiple wires pingyong the upper and lower direction bit which In the trolley wire by the Raleigh for a tower crane which, including the trolley winch which moves horizontally, installation of any one of a T-type crane and luffing crane types according to the workplace environment along the jib,
To fit seamlessly on T-type cranes or the roughing type crane is mounted on the jib, a frame, a roughing-type crane which is mounted to slide on the jib offset from Eve the same center line upon to prevent the mutual interference of the wire for use hoists It is disposed, respectively, the jib tip to bujjok sieve comprises a trolley assembly and eve when being fixed so as to step up to the lower position, yirwojin a frame with fixing means for locking or unlocking the jib end portion from the frame,
A T-type crane trolley is unlocked to be moved horizontally along the jib when used, the trolley is locked to the jib end portion when used as an L-type crane.
