STRADDLE CARRIER FOR USE IN CONTAINER TERMINALS AND FOR GENERAL TRANSPORT PURPOSES AND METHOD FOR THE CONTROL THEREOF
The invention relates to a straddle carrier (1) for use in container terminals and for general transport purposes, comprising a steering wheel (3), a brake pedal (4) and an accelerator pedal (5), the operator of the straddle carrier (1) being able to control said carrier by actuating said components, also comprising a steering drive (6), a brake drive (7) and a fuel dosing drive (8) by means of which the steering wheel actuation, brake pedal actuation or accelerator pedal acceleration is converted into the steering processes, braking processes and/or fuel dosing processes. In order to prevent the straddle carrier (1) from overturning in both extreme and dangerous situations, said straddle carrier (1) is equipped with a calculation unit (2) which is connected on one side to the steering wheel (3), the brake pedal (4) and the accelerator pedal (5), and on the other side to the steering drive (6), the brake drive (7) and the fuel dosing drive (8), in which the actual position of the centre of gravity (SPL), an actual curve radius (KR) and an actual speed (V) of the straddle carrier (1) can be continuously detected, and an actual range of the authorised operational state of the straddle carrier (1) can be continuously determined based on the detected actual value. Said calculation unit controls whether an operational state of the straddle carrier (1) actuated by the driver of the said straddle carrier (1) by correspondingly actuating the steering wheel (3), the brake pedal (4) and/or the accelerator pedal (5) is within the actual determined range of the authorised operational state of the straddle carrier, and if said test demonstrates that said straddle carrier (1) is in a momentary non-authorised operational state, then control signals can be changed between the operator of the steering wheel (3), the brake pedal (4) and/or the accelerator pedal (5) such that the operational state of the straddle carrier (1) driven by the operator can be attained as fast as possible without abandoning the momentary determined range of the authorised operational state of the straddle carrier (1).
The invention relates to a straddle carrier (1) for use in container terminals and for other transport purposes, comprising a frame (2), load receiving means (6) which are suspended between the frame (2) and which can be locked to a container (8), drive carriers (5) which are arranged in the lower region of the frame (2) and a plurality of wheels (15) which are arranged in a row, and screw jacks (9) for winding up and down the hoisting cable (10) and to which one end is connected to the screw jacks (9) which are guided by means of load receiving means and hoist cable bearing points (11, 12, 13) on the frame side. The aim of the invention is to reduce the load of the hoisting cables (10) of the straddle carrier (1) due to instantaneous loads during the operation thereof. As a result, a spring device is arranged on at least one hoist cable bearing point (11, 12, 13) of each hoist cable (10) of the straddle carrier (1) which enables instantaneous loads transferred to the hoist cable (10) to be dampened.
