As the core load-bearing and lifting component of electric forklifts, the mast directly determines the operation adaptability and scene matching degree of the equipment, and different mast structures bring distinct practical working effects for material handling work.

First, the core structural difference lays the foundation for performance divergence. The full-free-lift mast is equipped with an independent first-stage oil cylinder that drives the fork to rise for a certain distance before the inner mast starts to extend, so the overall height of the whole mast will not increase during the initial lifting process. For the standard duplex mast, the inner mast will synchronously rise with the fork at the first stage of lifting, leading to the immediate increase of the total mast height once the lifting action starts.

In terms of passage adaptability performance, the full-free-lift mast shows unique advantages in low-clearance working scenarios. It can lift the fork to a height of 1.5 meters without pushing the inner mast out, so the equipment can smoothly pass through low doorways of containers, enclosed carriages or low-clearance attic warehouses, and complete stacking work inside the narrow enclosed space. For the standard duplex mast, if the fork is lifted to the same 1.5 meters height, the overall mast height will exceed the common internal height of standard containers, so it can not enter the above-mentioned low space to complete normal lifting operation.

In terms of load stability and operation efficiency for conventional scenarios, the standard duplex mast has a relatively simpler structure with fewer transmission components, which presents steady load performance within the commonly used 3-meter to 5-meter lifting height range. It delivers smooth lifting and descending speed, and requires less daily maintenance work, which can meet the daily stacking demands of most ordinary flat warehouses. The full-free-lift mast is more suitable for operation teams that need to frequently switch between narrow low passages and high stack areas, as it avoids repeated adjustment of mast inclination angle when passing through low clearances, and simplifies the whole operation process.

When selecting the right mast type, operators can make decisions based on actual working scenarios rather than pursuing extra unnecessary functions, to give full play to the proper working value of electric forklifts.
