Many friends who know and Tieba are asking whether the electric gourd can be driving on the U -shaped or ring -shaped orbit. The majority of netizens also gave a lot of answers. However, when the customer is sure of the correct answer, it still takes a certain amount of energy and brainpower. In fact, as long as the electric gourd is equipped with a walking car, it can be used on the circular track. Generally, the electric gourd of the general manufacturer can achieve this function. However, you need to be equipped with rail beams and sliding lines. Pre -burying parts and reserved holes should be left on the structural beam. Of course, in order to save time and effort, Hebei Rizhi launched a ring -shaped rail electric gourd. Without multiple attachments, it can be drove directly on the circular orbital orbit. However, this electric gourd is a customized non -standard electric gourd that needs to be customized and the price will be relatively high. Customers can also choose according to their actual situation.
