Everyone knows forklifts, but many people may not know the forklift mast. Today, Wutong.com will introduce to you what is the forklift mast and how to use the forklift mast. Forklift mast manufacturers tell you

What is a forklift mast

Forklift mast (mast) is the main load-bearing structure of forklift load handler. The mechanism that lifts the goods is also called the mast. It is composed of inner main frame, outer main frame, fork frame, fork, sprocket, chain, lifting cylinder and tilting cylinder.

How to use forklift mast

According to the requirements of the lifting height of the forklift goods, the forklift mast can be made into two or more stages, and the common ordinary forklifts mostly use the two level mast. There are three-section full-free door frame, two-section full-free door frame, and two-section standard door frame. Among them, the full-free door frame can work in containers, and we usually call it the container door frame.

The two-level gantry is composed of an inner gantry and an outer gantry. The forks and forks suspended on the fork rack move up and down along the inner gantry by means of fork rack rollers to drive the goods to rise or fall. The inner mast is driven up and down by a lifting cylinder, and is also guided by rollers. There are tilt cylinders on both sides of the rear of the mast, which can make the mast tilt forward or backward (the maximum forward tilt angle of the mast is about 3'-6', and the rear elevation angle is about 10~13~). Picking and stacking goods sharply.

The lower end of the outer mast is hinged to the frame, and the middle part is hinged to the tilt cylinder. Due to the expansion and contraction of the tilt cylinder, the mast can be tilted forwards and backwards (the inclination is generally 6°~12°), so that the forklift and the cargo during the handling process are stable.

The inner door frame has rollers, which are embedded in the outer door frame, and the inner door frame can partially extend out of the outer door frame when it rises. The fork frame has rollers, which are embedded in the inner mast and can move up and down. The bottom of the lifting cylinder is fixed at the lower part of the outer mast, and the piston rod of the cylinder moves up and down along the guide rod on the inner mast. The top of the piston rod is equipped with a sprocket, one end of the lifting chain is fixed on the outer mast, and the other end goes around the sprocket and is connected to the fork frame. When the top of the piston rod lifts with the sprocket, the chain lifts the fork and the fork frame together. At the beginning of lifting, only the fork lifts up, and the inner main frame can only be lifted up after the piston rod reaches the inner main frame. The lifting speed of the inner main frame is 1/2 of the fork.

The maximum height that the fork can lift when the inner mast is not moving is called the free lift height. The general free lifting height is about 300 mm. After the fork frame is raised to the top of the inner main frame, the main frame that the inner main frame and the fork frame are raised at the same time is called the full-free lifting main frame. Forklift chains over 10 tons are mostly directly fixed on the top of the inner mast, and the lifting cylinder lifts the mast from the beginning, so it cannot be lifted freely. A forklift that lifts freely can enter a doorway slightly higher than it. The fully free-lifting forklift is used in low places and will not cause the forks to reach the required height due to the top of the inner mast on the roof, so it is also suitable for operation in cabins and containers. In order to enable the driver to have a better view, two lifting cylinders are used and arranged on both sides of the mast, which is called a wide view mast. This kind of door frame gradually replaces ordinary door frame
