    • To provide a counter weight capable of forming an attaching part to a vehicle frame with high precision, capable of improving attaching precision to this vehicle frame, and further, capable of decreasing a manufacture cost thereof. The counter weight includes a base made of cast iron having an attaching part, whereby the counter weight is attached to a vehicle frame; and a weight part made of a slab material having a block body made of a slab material; wherein the weight part made of the slab material is attached on the above-described base made of cast iron. The outer surface of the above-described weight part made of the slab material is coated with the cover. In addition, the connection plate is attached to the above-described base made of cast iron, the lower end edge of the above-described cover is joined to the base made of cast iron through the above-described connection plate, and the upper end edge of the above-described cover is joined to the upper part of the above-described weight part made of the slab material. Since the base made of cast iron is attached to the vehicle frame, it is possible to form the attaching part to the vehicle frame at a low cost, simply, and with high precession.
    • 为了提供能够高精度地形成车架的安装部的配重,能够提高该车架的安装精度,并且还能够降低制造成本。 配重包括由铸铁制成的基座,该基座具有安装部,由此将配重安装在车架上; 以及由具有由坯料制成的块体的板坯材料制成的重量部件; 其特征在于,由所述板坯材料构成的所述重量部分安装在上述由铸铁制成的基座上。 由板坯材料制成的上述重量部分的外表面涂覆有盖。 另外,连接板安装在上述由铸铁制成的基座上,上述盖的下端缘通过上述连接板与铸铁底座接合,上端 上述盖的边缘连接到由板坯材料制成的上述重量部分的上部。 由于将铸铁制成的基座安装在车架上,所以能够以低成本,简单且高进动地将安装部件形成在车架上。
