我们为了解决养路作业中的拨道问题,试制了一种小型手动液压拨道机(图1)。在钢筋混凝土轨枕地段用2～3台共同作业,在木枕地段用1台作业即可。机体总重22公斤(因利用现有材料,实际上机体重量还可以减轻)。 We tried to solve the problem of track maintenance work, trial production of a small manual hydraulic drive (Figure 1). In the reinforced concrete sleepers with 2 to 3 joint operations, in the wood pillow section with a homework can be. Body weight 22 kg (due to the use of existing materials, in fact, body weight can be reduced).
