Forklifts are of a wide variety, but whatever type of forklift, they are essentially made up of four main components: power-driven partiality, chassis, working locality and electrical equipment. Different types of forklifts are formed as a result of differences in the structure and location of the four main sites。
Forklifts are a most common form of forklifts. This type of forklift is used as an example to argue over the local composition。
(i) dynamic localization
Forklift power units function as a power source for handling cargo and tyre chassis operations for the forklift, generally
The rear of the forklift and the balancing of weights。
The power unit of the electric forklift, which is a battery storage and direct-flow string motor, has the closest driving properties to the requirements of the constant power soft properties and is better towed than the internal combustion engine. In addition, it operates without noise, without exhaust gas, with simplicity of overhaul and operation, with lower operating costs and longer life spans. The disadvantages are:
Charging equipment is required, with a high level of investment at the core, with a longer recharge time (general: 7-8h, rapid charge: 2-3h), short continuous working hours after a charge, and high demand for road surfaces due to the fear of impact vibrations on the batteries. Owing to battery capacity limitations, electric motor power is low and speed and ramp power is low. Thus, battery-driven forklifts driven by an electric battery are used mainly in warehouses and workshops where the corridor is narrower, the removal distance is not long, the surface is good, the weight is smaller and the speed of the vehicle is not too fast. Forklifts can only be used in flammable stores or where air is required to be clean。
The internal combustion engine in the refrigerated warehouse had difficulty starting. Battery forklifts should also be used。
The mechanical characteristics of the internal combustion engine do not meet the requirements for the constant power softness of the original motor of the forklift, and its output power increases with the speed of rotation. Therefore, the internal combustion engine must be equipped with an increased output rectangular mechanical transformer, a liquid rectangler or a hydraulic thruster. The main advantages of an internal combustion forklift and a battery forklift are:
There is no need for charging equipment, long duration of operations, high power, strong ramping power, low road requirements and minimal investment. Assuming that the right mode of movement is used, the ambition can be induced. The disadvantages are:
It operates with noise and vibrations, exhaust gas, high number of overhauls, higher operating costs and a shorter life span for the whole vehicle. Thus, forklifts are superior. When the average starting mass is above medium tonnage, preference should be given to the internal forklift。
Forklifts with internal combustion are the most common forklifts, with all forklifts weighing more than 3 t in their entirety. This is due to the low consumption of diesel fuel. But diesel engines are heavy, noise and vibration. Forklifts with smaller weights, which are small in size and light in weight but are fuel-intensive, are expensive, have more harmful components in the exhaust gas and are prone to fire. There are also forklifts abroad with liquefied petroleum gas engines, which have low fuel prices and lower emissions. In recent years, domestic and international forklifts have increasingly used liquid petroleum gas machines as power units, mostly dual-fuel forklifts, which can fuel gasoline or diesel or liquefied petroleum gas. Germany has an annual growth rate of 160 per cent forklifts using liquid petroleum gas, and the united states and japan are increasing. There is a growing opposition to vehicle tail gas pollution. Thus, in industrial vehicles driven by internal combustion engines, including forklifts, the use of liquid petroleum gas machines has become more widespread. This is due to the use of liquid petroleum gas engines, which not only avoid air pollution, reduce public hazards, but also reduce engine wear. Extension of engine life. It could also reduce fuel costs。
(ii) cylinder
The chassis withstands the power of the power unit, gives forklift power and guarantees its normal movement. It consists of a kinetic system, a drive system, a shift system, a brake system。
The transmission system is a device to withstand power and transmit it to the driving system。
Mechanical transmission systems consist of frictions, gear transformers, all-way transmissions and primary transmissions and differentials installed within the driving bridge; liquid mechanical transfer systems replace frictions with liquid rectangles, with the rest being the same as the former。
The driving system is a device to ensure that the forklift is rolling and supports the whole forklift. It consists of a stand, a bridge, a wheel and a hanger; the front bridge of the forklift is a bridge driven to increase the front axle of the bridge when it is loaded for removal, to improve the quality attached to the wheel and to increase the strength of the ground to ensure that the engine is fully driven. The bridge was then turned。
The gearing device is in front of the driver and the gearing rods, such as the speed rod, are placed on the right side of the driver's seat。
The shift is a system used to make the forklift move in the intended direction of the driver, and the forklift shift is different in terms of the energy required for the shift, divided into mechanical and power shifts. The former shift from the driver's body to the energy source, which is made up of a shifter, a mover and a manipulator:
The latter is a shift device that uses both the driver's body and engine power for energy switching. In normal conditions, the forklifts turn to the energy required, with only a small portion being supplied by the driver and a large part by the engine through the switch to a booster. However, when the shift to a force-added device fails, the driver should generally be able to perform the shift independently. Forklifts are operated with a shift in mobility and, in order to reduce the driver's manoeuvring burden, the internal forklifts are subject to a power shift device. The commonly used power rotations consist of a total power converter, a semi-integrated power transformer and three steering thrusters. The brake system is a system for slowing or parking forklifts. It consists of brakes and brakes. The brakes are three types of manual brakes, power brakes and server brakes classified by the brake energy. The former is based on the driver's body
Dynamic energy; the power brake system is entirely dependent on the power transformation of the engine, and the power of the pressure or hydraulic form is the brake energy; the latter is a combination of the first two。
The composition of the chassis of the forklift and other parts of its composition, function and working principles are similar to those of the car, so that the content of that part, which is the same as that of the car, will be presented because it is limited to space and is not elaborated upon, but different from that of the vehicle。
In the forklift, the rear of the forklift is weighed to balance the quality of the goods in the front of the forklift, the power unit of the forklift [internal combustion engine] or batteries, which are typically packed in the back of a forklift to function as a local balance。
(iii) part of the job
The forklift works in part to carry the full load directly, to complete the process of forklifting, lift, stacking, etc. Of the goods, and consists of a work unit for direct progress handling and a hydraulic transfer system for manipulation of work unit movements. It takes a variety of forms, both in design and in different working conditions。
The forklift is a forklift component that directly carries the goods and is mounted on the forklift by hooking, and the distance between the two forklifts can be adjusted to the needs of the operation and locked by the positioning device。
The fork frame is a construction made of steel plates welded and has a roller group, a slot track in the upper and lower direction on the inside side of the door frame, which is also connected to the inner door frame, and can only move up and down along the orbit of the outer shelf。
The inner doors are being welded by two slots of poles and beams
