Crank arm side ladder and fire fighting truck
The invention discloses a crank arm side ladder and a fire fighting truck. The crank arm side ladder comprises a side ladder assembly, and the side ladder assembly comprises lower chords, upper chords, connecting rods and a driving system; the lower chords and the upper chords are arranged at intervals in the vertical direction and are parallel to each other; the connecting rods provide connectionbetween the lower chords and the upper chords, and the connecting rods are configured to be capable of rotating relative to the lower chords and the upper chords so as to enable the upper chords to be close to or far away from the lower chords; and the driving system is configured to be capable of driving the connecting rods to rotate relative to the lower chords and the upper chords. The unfolding and folding operation difficulty of the crank arm side ladder is small, manual operation is not needed, both time and labor are saved, and meanwhile the safety of operators is improved.
本发明公开了一种曲臂侧梯以及消防车，所述曲臂侧梯包括侧梯组件，所述侧梯组件包括下弦杆、上弦杆、连接杆以及驱动系统；所述下弦杆和所述上弦杆沿竖直方向间隔布置并相互平行；所述连接杆在所述下弦杆和所述上弦杆之间提供连接，所述连接杆配置为能够相对于所述下弦杆和所述上弦杆转动以使所述上弦杆靠近或远离所述下弦杆；所述驱动系统配置为能够驱动所述连接杆相对于所述下弦杆和所述上弦杆转动。本发明的曲臂侧梯的展开及回收操作的难度较小，且无需手动操作，省时省力，同时提高了操作人员的安全性。
