本考案はタワークレーンのタワー支持ロープ取

As shown in FIG. 1, the tower crane 1 has a tower boom 3 pivotally attached to a crane body 2, and a wire rope 5, an intermediate pulley 6, and a pendant rope 7, which are unwound from a hoisting drum 4 provided at the rear of the crane body 2. A backstop 8 is installed to support the tower boom 3 from the rear via a turnbuckle 10 to prevent the tower boom 3 from falling backward, and a turnbuckle 10 is attached to a tower support rope mount 9 attached to the front of the crane body 2. The tower support rope 11 is tensioned to prevent the tower boom 3 from falling behind the crane body 2.
ところで、タワーブーム３は垂直に近い角度で
長さも相当にあるため、前記バツクストツプ８の

バツクストツプ８をタワーブーム３の上方で支持

より、これを防止するために前記の如くタワー支
持ロープを設けているのである。 By the way, since the tower boom 3 has a nearly vertical angle and a considerable length, it is difficult to support the tower boom 3 from falling backward using only the backstop 8.
Although it is conceivable to support the backstop 8 above the tower boom 3, the backstop 8 becomes long and uneconomical. Furthermore, if only the backstop 8 is supported, when the suspended load is lowered (when there is no load), the tower above the support point of the backstop 8 will be pushed backwards, which is extremely dangerous. Therefore, in order to prevent this, tower support ropes have been conventionally provided as described above.

第３図に示す取付台９をクレーン本体２の前部ブ
ラケツト１２に２本のピン１４，１４で固設する
構造となつている。 As shown in FIG. 2, the conventional tower support rope mount 9 is pivoted to the front bracket 12 of the crane body with a pin 13, and the turnbuckle 10 is reduced until the mount 9 comes into contact with the front part of the crane body 2. The structure is such that the tower support rope 11 is tensioned, and the mounting base 9 shown in FIG. 3 is fixed to the front bracket 12 of the crane body 2 with two pins 14, 14.
しかしながら第２図に示す構造では取付台９は

の欠点がある。 However, in the structure shown in Fig. 2, the mount 9 must be removed from the crane body 2 during transportation, and the tip of the mount 9 is in contact with the ground during assembly, so the adjustment allowance for the turnbuckle 10 is large and tension adjustment is troublesome. Moreover, in the structure shown in FIG. 3, since the mounting base 9 is fixed to the crane body 2 with a pin 14, there are drawbacks such as difficulty in adjusting the tension of the turnbuckle 10.

In order to achieve the above object, the present invention has one end fixed to the top of the tower and the other end of the tower support rope fixed to the tower support rope mount provided protruding forward at the front of the crane body of a mobile tower crane. In a tower support rope attachment device for a tower crane that connects and supports the tower boom so that it does not fall behind the crane body, the tower support rope attachment base is attached to a bracket at the front of the crane body with a pin so as to be movable up and down. At the same time, a stopper is attached to the mounting base that comes into contact with the bracket in order to support the mounting base on the bracket in a substantially horizontal state when the tower support rope is loosened, and a stopper is attached to the mounting base to support the mounting base on the bracket when the tower support rope is tensed. It is characterized in that a stopper that comes into contact with the bracket with some play against time is attached to the mounting base.
