The invention discloses a multifunctional flat-arm tower crane capable of being used for fire fighting. The multifunctional flat-arm tower crane comprises a tower crane body, a cargo boom and a balance arm, the cargo boom comprises a first arm section, a second arm section and a third arm section which are sequentially hinged, a winch is arranged on the balance arm, the winch is connected to the third arm section by winding a first steel wire rope around a fixed pulley at the top of a tower cap, and a fire fighting device and a clamping device are arranged on the third arm section. Fire fighting is conducted through the fire fighting device arranged on the third arm section, the height of the third arm section is increased through the pulling force of the winch, and therefore the fire fighting device can conduct fire fighting on a building with the height higher than the limit height of the cargo boom.
本发明公开一种可用于消防的多功能平臂塔机,包括塔机本体、起重臂和平衡臂,所述起重臂包括依次铰接的第一臂节、第二臂节和第三臂节,平衡臂上设有卷扬机,所述卷扬机通过第一钢丝绳绕过塔帽的顶部的固定滑轮连接于第三臂节上,所述第三臂节上设有消防装置和夹紧装置。本发明通过设置于第三臂节上的消防装置进行消防,通过卷扬机的拉力来提高第三臂节的高度,使得消防装置可以对高于起重臂极限高度的建筑进行消防。
