| 简介 |
The present invention relates to an underlift wrecker, comprising a cabin providing an internal space in which a worker can get in, and a towing unit installed in a rear side of the cabin and transporting a towed vehicle. The towing unit includes a cabin-installed type frame inserted into the cabin to connect the cabin and the towing unit to increase an overall rigidity of the wrecker, thus preventing a situation in which the frame is bent or cut due to a load of the towed vehicle. The underlift wrecker includes a buffer unit preventing a rear wheel from sinking due to a load applied to the rear wheel by the towed vehicle when the towed vehicle is transported. The buffer unit includes a rear wheel buffer member having one side connected to the cabin-installed type frame, and an other side connected to the rear wheel to absorb an impact applied to the rear wheel or vibration, enhancing stability. The underlift wrecker includes a low pressure accumulator canceling out a load by buffering a fluid within the rear wheel buffer member when a load applied to the rear wheel is lower than a set pressure, and a middle pressure accumulator canceling out a load by buffering a fluid within the rear wheel buffer member when the load applied to the rear wheel is higher than the set pressure, whereby the rear wheel buffer member is able to be operated according to situations.COPYRIGHT KIPO 2016 |
