Forklift gantry

Abstract

The invention relates to a forklift gantry which comprises four classes of gantries and a goods fork frame, wherein two rear lifting oil cylinders are uniformly distributed on a connecting plate of the first class gantry, and the piston rod ends of the rear lifting oil cylinders are connected with the second class gantry; a second class chain wheel, a second class chain, the second class gantry and the first class gantry form a moving chain wheel group; the third class chain wheel, the third class chain, the second class gantry and the highest class gantry form a moving chain wheel group; and the third class gantry and the highest class gantry are pulled by the chains to move relative to the first class gantry under the interaction of the rear lifting oil cylinders and the chains. Front lifting oil cylinders are uniformly distributed on the highest class gantry; the piston rod ends of the front lifting oil cylinders are provided with two chain wheels; and one ends of the two chains matched with the chain wheels are connected with the highest class gantry, and the other ends are connected with the rear part of the goods fork frame. The chain wheels, the chains, the highest class gantry and the goods fork frame form a moving chain wheel group; and the goods fork frame can move relative to the highest class gantry. The four groups of gantries are compactly distributed and are basically distributed in parallel, thereby ensuring minimal front suspension and favorable visual field.

Description

technical field [0001] The invention belongs to the technical field of forklifts, and in particular relates to a forklift mast. Background technique [0002] The forklift mast is the executive component for stacking goods during the forklift operation. At present, the domestic forklift mast only has two-section masts and three-section masts. In some specific working conditions, the user requires the mast to be able to lift at a high level and pass at a low level. The so-called high lift means that the goods can be sent to a higher place after the mast is lifted, and the low pass means that the height of the entire mast is low after the mast is retracted, so that the forklift can pass through the low warehouse door or enter the low warehouse. Space operation, the existing ordinary gantry can hardly meet the requirements of users. The existing two-section gantry can lift up to 6 meters, the three-section gantry can lift up to 7 meters, and the two-section 6-meter gantry can l...

Problems solved by technology

The so-called high lift means that the goods can be sent to a higher place after the mast is lifted, and the low pass means that the height of the entire mast is low after the mast is retracted, so that the forklift can pass through the low warehouse door or enter the low warehouse. Space operation, the existing ordinary gantry can hardly meet the requirements of users. The existing two-section gantry can lift up to 6 meters, the three-section gantry can lift up to 7 meters, and the two-section 6-meter gantry can lift all The height of the mast after retracting is 3600mm, and the height of all the masts of the three-section 7-meter mast is 3031mm after retracting. Objects must be retrieved through a warehouse door less than 3000mm or into a low space such as a cabin at this height, and the current forklift mast cannot meet this working condition
