Abstract
The invention relates to a four-wheeled hand truck capable of travelling longitudinally and transversely. The four-wheeled hand truck comprises a frame, a handle connected with the frame, a pair of front rollers and a pair of rear rollers, and the front rollers and the rear rollers are arranged below the frame. Each front roller and each rear roller are mounted on a front roller bracket and a rear roller bracket which are provided with vertical rotating shafts, and then are rotatably arranged on the frame; and rotatable angles are not less than 90 degrees. Besides, rotary linkage operating mechanisms are arranged. When the four-wheeled hand truck needs to be changed from straight travelling into transverse travelling, the rotary linkage operating mechanisms only need to be operated in place to enable the front and rear rollers to turn 90 degrees simultaneously, the frame needs not to be rotated, and accordingly straight travelling is changed into transverse travelling.
Description
Technical field
