Basic structure and functions of forklift
1. Engine
It is the power source of internal combustion vehicles. It converts the thermal energy generated by the fuel into mechanical energy and outputs power through the engine’s flywheel.
2. Chassis
The chassis is used to support the body, receive the power output from the engine, and ensure that the vehicle can drive normally. It includes transmission device, driving device, steering device and braking device, etc.
3. Car body
The body and frame of the forklift are integrated and welded by section steel. The cast iron block placed at the rear of the forklift and suitable for the vehicle model is a counterweight. Its weight is determined according to the rated lifting capacity of the forklift and plays a balancing role when the truck is loaded. To maintain the stability of the vehicle
4. Lifting mechanism The lifting mechanism mainly consists of a mast and a cargo fork. The mast is hinged to the front axle support body and consists of a set of parallel steel frames and sliding brackets that fix the cargo. The goods are two steel forks bent at 90°, mounted on sliding brackets, and are tools for carrying materials. The specifications of the truck are designed based on the maximum load of the truck. The cargo can be tilted forward and backward by means of a hydraulic cylinder.
5. The hydraulic system mainly includes:
(1) Lifting hydraulic cylinder, the top of its plunger is fastened to the lifting mast to control the lifting or lowering of the fork.
(2) Tilt hydraulic cylinder, the top of its plunger is hinged with the mast to control the forward or backward tilt of the mast.
(3) Hydraulic pump, which can be a vane pump or a gear pump. The hydraulic pump outputs high-pressure oil (6.37~15.7MPa) to drive the lifting hydraulic cylinder and tilt hydraulic cylinder.
(4) Hydraulic distribution valve, consisting of a valve body, a lifting hydraulic cylinder valve core, a tilt hydraulic cylinder valve core and a safety valve. Its function is to control the action of the lifting or tilting hydraulic cylinder spool through the control handle according to the lifting and tilting requirements of the fork, and to input high-pressure oil into the lifting or tilting hydraulic cylinder. The function of the safety valve is to allow the oil to flow back from the oil return pipe to the tank when the oil pressure in the system exceeds a certain value.
(5) The throttle valve is installed in the pipeline of the lifting hydraulic cylinder. Its function is to increase the flow resistance of the oil. When the lifting hydraulic cylinder releases pressure, it ensures that the cargo descends slowly.
6. Electrical equipment
Electrical equipment consists of power supply, engine starting system and ignition system, as well as forklift lighting, signals and other electrical equipment.
What are the main forklift accessories? The forklift is mainly composed of five major systems: electric power unit, chassis, working device and electrical equipment, and these five systems are composed of thousands of forklift accessories. The English name is forklit pars, and the power of the forklift is Device, internal combustion counterbalanced forklift, which is mainly powered by an internal combustion engine. Internal combustion engines mainly include gasoline engines, diesel engines, liquid petroleum gas (natural gas) engines, and dual-fuel engines. It is composed of internal combustion engine (engine), transmission drive device, operating control device, working device and electrical equipment.

4. Working equipment
Also known as the lifting structure, it is mainly composed of mechanical parts and hydraulic systems. Working devices can be divided into three types: gantry type, parallel link type and boom telescopic type, among which the gantry type is the most widely used. Specific accessories can be classified into cargo forks, holding clamps, paper roll clamps, skewers, rotating frames, steel claws, buckets, cargo sleeves, components and clamping parts that are placed on the cargo forks to increase the load-bearing length. , attachments for holding cargo, bucket clamps, skewers, pick rods, hooks, and booms. Booms and hooks used for lifting operations, cargo forks that tip over the cargo and tip over together with the shelves, and swings. Cargo forks, used for loading and unloading cylindrical goods, can swing left and right around the upper hinge point of the fork, hinged tipping forks, slewing forks, load stabilizers, container spreaders, attachments for lifting and transporting containers, Tipping bucket, bucket, attachments for loading and unloading bulk materials, push-pull, ejector, No. 2 ejector, attachments that can push goods out of the cargo, three-way forks, which can be used in front of the forklift and on the left and right sides Attachments for loading and unloading cargo, rotary clamps, attachments for holding cargo that can rotate around the horizontal axis, side-shift cargo hooks, attachments that can move the cargo beam laterally, forward-shift cargo hooks, adjustable-spacing cargo forks, The spacing can be adjusted by hydraulic cylinders, and it consists of various attachments such as forks, log clamps, and side shifts.
