四向电动叉车结构复杂,制造成本较高。四向电动叉车集前移式叉车、侧叉、平衡重式叉车的功能于一体。在构造上它和前移式叉车基本相同,门架位于前后车轮之间,在又车前方有呈臂状伸出的两条插腿,插腿前端装有支撑轮,货又可随门架在叉车纵向前后移动。叉货卸货时,货叉伸出,叉卸货物后货叉退回到接近车体的中间位置,因此叉车行驶的稳定性大大提高。与前移式叉车不同之处在于,四向电动叉车叉腿前端的两个承重轮可以通过转向机构回转90°当后轮转过90°时,整个叉车可以从前后行驶的状态就地变为左右行驶,相当于侧叉,因此适合更窄通道的长形物料搬运。最小通道宽度通常可以在2米以内。
The structure of four-way electric forklift is complex and its
manufacturing cost is high. The four-way electric forklift integrates
the functions of the forward moving forklift, the side fork and the
counterweight forklift. In terms of structure, it is basically the same
as the forward-moving forklift truck. The gantry is located between the
front and rear wheels, and there are two outriggers extending in arm
shape in front of the second truck. The front end of the outrigger is
equipped with a supporting wheel, and the goods can move forward and
backward along with the gantry in the longitudinal direction of the
forklift truck. When the forks are unloaded, the forks extend out. After
the forks are unloaded, the forks return to the middle position close
to the vehicle body, so the stability of forklift driving is greatly
improved. The difference between the four-way electric forklift and the
forward-moving forklift is that the two load-bearing wheels at the front
of the fork leg of the four-way electric forklift can rotate 90 °
through the steering mechanism. When the rear wheel rotates 90 °, the
whole forklift can change from the state of front and rear driving to
the state of left and right driving locally, which is equivalent to the
side fork, so it is suitable for the long material handling in a
narrower passage. The minimum channel width can usually be within 2
meters.
