Description

The invention relates to cranes and can be used in the construction of mobile cranes with a beam articulated boom.

The purpose of the invention is to simplify installation and disassembly.

Fig 1 shows the crane in the working position, Fig 2 and 3 show the crane when it is transferred to the transport position in Fig 4 - the crane is in the transport position

On the undercarriage 1 of the crane is installed a rotary platform 2 with blocks 3 and a winch 4 lifting cargo. On the rotary platform 2 there is a counterweight 5, a bracket with a hinge 6 a telescopic tower consisting of a fixed section 7 and a sliding section 8

A block 9 is installed in the upper part of section 7. A hydraulic cylinder 10 serves to tilt the telescopic tower. The articulated beam type boom consists of a base 11 and a tip 12 which are connected by a hinge 1 in i. arrows Arrow ball (irn „f

section 8 inside section 7. At the same time, the boom tip 12 takes up a vertical position by the force of gravity by moving the rope 17 (Fig. 2). The base 11 of the boom remains in a horizontal position and is held by the ropes 18-20. By turning on the cargo winch 4, the slack of the rope 24 is selected and the boom head 12 is pulled under the base of the boom 11 (Fig. 3). Next, the tower and the boom in one package is lowered with the help of a hydraulic cylinder 10 into the transport position,

Mount the valve in reverse order.

Claims (1)

Claims of the invention A tower crown comprising a turntable mounted on the chassis, on which a telescopic tower with articulated two-section boom is mounted with the possibility of forced rotation, a freight carriage, a rope, which is connected to the free end of the winch at one end and the other end connected the boom head, and the raskalnoe system, which includes a hinge mounted on the tower and at the junction points of the base of the boom with its head and stand tower and stock bypassed ropes, characterized in that, for the purpose of simplifying installation and dismantling, the ropes of the pitching system are fixed by one ends on the lower part of the tower's sliding section, one of them is stored in bypass blocks that are mounted on the upper parts of the lower section of the tower and on the turntable, and mounted on racks associated with the tower, and on the base of the boom, and the other - in the bypass blocks, which are mounted on the turntable and on racks associated with the turret and mounted on the rack associated with the boom head and on the latter. nineteen 17 Riga.1 P 21 /9 Fig j eleven 16 P 8 9 / 7 P / J 21
