A material handling vehicle (1) comprising, a device (8) for lifting and carrying a load, at least a pair of vertical wheels (6), an underside (13), an upper side (12), an energy source (14), a travel motor (16), wherein the material handling vehicle (1) is arranged such that it is able to travel in under a load, lift and transport the load (50), further the material handling vehicle (1) comprises at least one first electromagnet (21) on the underside (13) of the vehicle (1), such that when the electromagnet (21) is supplied with electric power it will be able to attach the material handling vehicle (1) to a magnetic surface (40), wherein the electromagnet (21) is movably attached in the material handling vehicle (1) such that the electromagnet (21) is able to move in vertical direction in relation to the underside (13) of the vehicle (1), wherein the electromagnet (21) is able to follow the magnetic surface (40) as the surface (40) moves in vertical direction in relation to the underside (13) of the material handling vehicle (13), wherein the electromagnet (21) is able to move to between a first and a second end position (I, II), wherein the first end position (I) is a retracted position and the second position (II) is an extend position in relation to the underside (13) of the vehicle (1), at which second position (II) the distance of the lower most surface (37) of the electromagnet (21) to the underside (13) of the vehicle (1) has a predetermined value (X), wherein the material handling vehicle (1) further comprises a sensor (15) at the underside (13) of the vehicle, which sensor (15) is able to control the supply of electric power to the electromagnet (21) based on a detected distance from the sensor (15) to the surface (40) positioned next to the underside (13), wherein the sensor (15) is arranged to have a detection range (R) that is smaller than then predetermined value (X) of the distance of the lower most surface (37) of the electromagnet (21) to the underside (13) of the vehicle (1).
