![]() After this, the mast sections extend telescopically. The mast with three mast sections and a central cylinder provides first of all a free lift when lifting. Mast with three mast sections and a middle cylinder Lift heights: up to 3,700 millimetres (higher only in exceptional situations).Disadvantages: not very suitable for higher lifting heights and limited visibility due to the centre cylinder.This type of mast also has various names: 2-part mast with full free lift, FFL mast (full free lift), HILO mast (high-low) or NIHO mast (niedrig-hoch). First the fork carriage reaches maximum free lift, then the inner mast extends. The combination of a simplex mast and a duplex mast brings the best of both worlds. Lift heights: up to approximately 5,000 millimetres.Advantages: simple construction, good visibility.Other names for the standard lifting mast are: duplex, 2-part mast without free lift or telescopic mast. At the same time, the chains – which are attached to the outer mast – roll over the inner mast and thus lift the fork carriage. The hydraulic system pushes the inner mast section up. The standard mast is equipped with two mast sections, one of which extends as soon as it is lifted. Disadvantages: low lifting heights, maximum 2,000 millimetres. ![]() Advantages: simple, good visibility and free lift as standard.This type is rare on lift trucks, but it is widely used on stackers. A hydraulic cylinder placed in the middle ensures the movement of the fork carriage. The mast with only a mast frame in which the fork carriage moves up and down is the simplest version. Free lift will stop if part of the fork or carriage rises above the mast. The free lift: the space that is created when the forks are raised, without increasing the overall height.The height of the driver’s protective grille also determines the clearance height of the truck. This size is directly linked to the lifting height. The building height is important at low underpasses. The height of the mast: the height of the mast when the mast is not extended.With a forklift truck, calculations are made from the floor to the top of the fork. The lifting height: the maximum height that the forks can reach.The mast plays an indispensable role in the functioning of the forklift however does also obstruct the driver’s view. The ability of the driver to see through the mast. Terms relating to forklift truck mastsįor a better understanding of the forklift lifting mast we explain some terms. ![]() The mast itself consists of 1 or more mast parts and a fork carriage (on which the forks hang), chains and hydraulic cylinders. There are, for example, a pump, valves (valves) and cylinders that take care of the movements. Hydraulic systemįirst of all it is important to explain that a hydraulic system is responsible for the movements of the mast. Below we give you an explanation to choose the right forklift mast for you however you can always contact us for professional advice. It is therefore high time to provide text and explanation about the features and the various designs. And to make it complex, the manufacturers also give their lifting mast a different name. Various types of lifting masts are available on the market. The mast is perhaps the most important part of a lift truck.
