The present invention relates to a multifunctional forklift truck including a steering device for working. The multifunctional forklift truck including a steering device for working comprises: an automotive cockpit; a chassis which supports the automotive cockpit and includes a steering wheel; a mast which is installed at a rear portion of the chassis and has a forklift function; and a forklift cockpit which operates the mast. In particular, since the steering device for the working is installed on the chassis to be steered at an angle greater than a steering angle of the steering wheel, steering can be performed at the time of driving by using the steering wheel, and the steering can be performed at the time of working in a state in which the steering wheel for the working lifts the steering wheel from the ground. Accordingly, the steering can be performed even in a narrow space to perform working while steering in a confined work space.
