Abstract
Abstract A truck designed to handle loads. The truck comprises a truck body which is movable by means of driving wheels. The truck body may be raised and lowered relative to the driving wheels, both in order to compensate for differences in levels between the loading bridge and the loading platform on a lorry and in order to compensate for any inclination of the lorry loading platform. The truck is provided with one or several lifting forks to handle loading pallets. The forks are comparatively long and are provided at their front ends with steerable support wheels which are also arranged to be operated for raising and lowering movements.
