る。2. Description of the Related Art Conventionally, as shown in FIG. 6, a steel cable connecting socket D is fixed to a terminal of a steel cable C for suspending a hook block F in a pulley storage section A at the tip of a telescopic boom B, as shown in FIG. The upper ends of a pair of arms E protruding upward from both upper sides of D are detachably pinned P to a bracket attached to the outer plate of the pulley storage section A, so that a hook block or a hook hanging rope according to the load is provided. Since the number can be increased or decreased, the height difference between the pulley support shaft G at the end of the boom and the steel cable connecting portion to the socket D becomes large as shown by H, and the lift of the suspended load decreases accordingly. Will be.

ツクブロツクが滑車収納部に対しねじれる恐れがある。In order to avoid this, the arm E of the steel cable connecting socket D is detachably pinned to an appropriate position on the side surface of the pulley housing A, and the guide of the steel cable connected to the socket is connected to the pulley housing A.
When the hook is mounted at the hook block hanging position on the side surface of the pulley, the distance between the steel cable guide and the end pulley in the adjacent pulley storage section A increases, and the torsion of the hook block with respect to the pulley storage section increases. Became the actual Kaihei 3-82
As in the hook block storage device described in the prior art of Japanese Patent No. 389, it is difficult to retract and store the hook block at the lower end of the pulley storage portion A of the horizontal boom by winding up the steel cable C with the winding drum device. In addition, the hook block F is attached to the lower surface of the hook block storage pendulum member K which is eccentrically attached to the pulley storage portion A and eccentrically from the pulley support shaft G.
When the hook block is retracted along the lower surface of the boom by winding the steel cable C after the top surface of the pendulum is brought into abutment engagement, the length of the pendulum member K is shortened as shown in FIG. It becomes impossible to increase the lifting height of the suspended load as much as possible and to reduce the disorder of the storage position of the hook block. Further, when lifting a long steel material or load, the hook block may be twisted with respect to the pulley storage portion as the load is lifted.

ことである。The problem to be solved is that a steel cable end is easily attached to and detached from the pulley storage portion at the end of the boom so that the distance between the steel cable connecting socket and the pulley adjacent thereto is reduced. It is difficult to make the hook block small enough to prevent the hook block from being twisted with respect to the pulley storage portion, and to shorten the entire length of the steel cable connecting socket to increase the lifting lift.

吊荷揚程を更に増加し得る効果を奏する。Further, if the straight steel cable portion which starts transmitting the load to the steel cable connecting socket intersects with the center line of both side trunnions fixed near the upper end of the socket,
Reduce the protrusion length of the pulley storage section from the bottom of the boom,
This has the effect of further increasing the lift of the suspended load.
