Construction Machinery Knowledge - Forklift

A lifting vehicle that uses a fork or other work device to load and unload cargo on its own. It is a material handling machine. Widely used in various departments of the national economy such as stations, ports, airports, factories, and warehouses, it is an efficient equipment for mechanized handling, stacking, and short-distance transportation. Self-propelled forklift appeared in 1917. During the Second World War, the forklift developed. China began manufacturing forklifts from the early 1950s. Forklifts are classified according to the structure: balance forklift trucks, forklift trucks, side forklifts, forklift trucks, straddle cars and special forklifts. One of the most widely used counterweight forklift trucks, often referred to as a forklift. Most of the objects handled by forklift trucks are items. After changing the fork into various devices (forklift attachments), it can carry a variety of goods. Forklift mainly consists of the following devices: 1 power device. Such as internal combustion engines and battery-motors. 2 transmission. Divided into mechanical, hydraulic and hydraulic transmissions. 3 steering device. Such as steering gear, steering wheel, steering rod and so on. 4 working device. Also known as the gantry, it consists of an inner mast, an outer mast, a fork rack, a fork, a sprocket, a chain, a lift cylinder, and a tilt cylinder. 5 hydraulic system and braking device. The main parameter that indicates the performance of the forklift is the rated lifting weight at the standard lifting height and standard load center distance. The center distance of the load is the distance between the center of gravity of the cargo and the front wall of the vertical section of the fork.

The forklift is a self-propelled loading and unloading and transporting machine with a gantry and a fork as working devices. Can be used for loading and unloading, stacking into pieces of goods. After replacing the working device, it can also be used for loading and unloading of special items and bulk materials.

The forklift consists of three parts: the power unit, the wheel chassis and the working device. The working device includes a mast, a chain, a fork, a fork and a hydraulic cylinder. The gantry is a telescopic structure that is hinged on the axle or frame and can be tilted back and forth by tilting hydraulic cylinders to facilitate loading and unloading of cargo and cargo driving. The lifting hydraulic cylinder drives the forks along with the fork to rise and fall along the inner mast through the chain drive. The outer mast of the inner door fork extends and retracts the rails up and down so that the forklift can lift the goods to a lower mast height. High height.

According to the power device, there are two kinds of battery forklifts and internal combustion forklifts. According to the forklift's structural characteristics, it can be divided into two types: straight fork balance weight type, leg type, forward type, side fork type and various special purpose forklifts. Among them, the straight-fork counterweight forklift is most commonly used. Straight fork counterbalanced forklift. The fork is mounted on the front of the body and extends out of the centerline of the front wheel. In order to balance the overturning moment caused by the weight of the cargo, a counterweight is installed at the rear of the vehicle body, and the forklift is moved forward and backward to carry out the forklift unloading cargo during the operation. Plug type forklift. Two arm-like legs project forward. Small-diameter wheels are installed at the front end of the legs. When the work is carried out, the forks are inserted into the bottom of the cargo together with the legs, and then the forks are lifted. Since the cargo is located in the bearing surface of the wheel, the stability of the entire vehicle is good. Reach truck. It is a variant of a forklift with forklift. The fork can move longitudinally back and forth in the forklift. When the cargo is loaded or unloaded, the fork is extended. When the cargo is loaded and unloaded, it is returned to the middle of the vehicle body. The stability of the vehicle is good. Side forklift. The gantry and fork are located on the side of the forklift. They are located in the middle of the body and can move horizontally together. They are suitable for transporting long pieces of goods. When the forklift is traveling, the goods are placed on the body platform and the stability of the vehicle is good.

The main technical parameters of a forklift are the rated load and the maximum lifting height. Forklifts are not only highly efficient, but also easy to replace. In recent years, they have developed rapidly. There are more than 30 kinds of work equipment that can be replaced. For example, the side-loading side clamp device can transport oil barrels and bundles; the replacement string bar device can transport steel coils and cement pipes; the replacement lifting arm and hook can lift various heavy objects; and the replacement bucket can be used for loading and unloading. Material and so on. Forklifts are flexible, adaptable, and highly efficient. Forklifts can be used for mechanization of loading and unloading operations, reducing cargo damage, and improving the utilization rate of warehouse volume and operating safety. Therefore, it is widely used by various departments.
