低成本、率、以工作质量保证产品质量

Forklifts are more and more widely used in various industries. Let's take you to know the composition of forklift.

叉车

Forklift

1、发动机

1. Engine

它是内燃叉车的动力源。通过发动机的飞轮向外输出动力。

It is the power source of internal combustion forklift. Power is output through the flywheel of the engine.

2、底盘

2. Chassis

底盘用来支承车身、接受发动机输出的动力，并保证叉车能够正常行驶。它包括传动装置、行驶装置、转向装置和制动装置等。

The chassis is used to support the body, receive the power output by the engine, and ensure the normal operation of the forklift. It includes transmission device, driving device, steering device, braking device, etc.

3、车体

3. Car body

叉车的车体与车架合为一体，由型钢组焊而成。置于叉车后部、与车型相适应的铸铁块为配重，其重量根据叉车额定起重量的大小而决定，在叉车载重时起平衡作用。以保持叉车的稳定性。

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 the counterweight, and its weight is determined according to the rated lifting capacity of the forklift, which plays a balance role when the forklift is loaded. To maintain the stability of the forklift.

4、起升机构

4. Lifting mechanism

起升机构主要由门架和货叉组成。门架铰接在前桥支架车体上，由一套并列的钢框架和固定货叉的滑动支架所组成。

The lifting mechanism is mainly composed of gantry and fork. The gantry is hinged on the front axle support body and is composed of a set of parallel steel frames and sliding supports for fixing the fork.

货叉是两个弯曲90°的钢叉，装在滑动支架上，是承载物料的工具。货叉的规格是根据叉车的Z大载荷而设计的。货叉可藉液压缸前倾后仰。

The fork is two steel forks bent 90 ° and installed on the sliding support. It is a tool for carrying materials. The specification of fork is designed according to the Z heavy load of forklift. The fork can be tilted forward and backward by hydraulic cylinder.

5、液压系统主要有：

5. The hydraulic system mainly includes:

（1）升降液压缸，其柱塞顶端与升降门架固紧在一起，控制货叉的起升或降落。

(1) The top of the plunger of the lifting hydraulic cylinder is fixed with the lifting door frame to control the lifting or lowering of the fork.

（2）倾斜液压缸，其柱塞顶端与门架铰接，控制门架的前倾或后仰。

(2) The top of the plunger of the tilt hydraulic cylinder is hinged with the gantry to control the forward tilt or backward tilt of the gantry.

（3）液压泵，可以是叶片泵或齿轮泵。液压泵输出高压油（6.37~15.7MPa），驱动升降液压缸和倾斜液压缸。

(3) Hydraulic pump, which can be vane pump or gear pump. The hydraulic pump outputs high-pressure oil (6.37 ~ 15.7mpa) to drive the lifting hydraulic cylinder and tilt hydraulic cylinder.

（4）液压分配阀，由阀体、升降液压缸阀芯，倾斜液压缸阀芯组成。其作用是按货叉升降和倾斜的工作需要，通过操纵手柄控制升降或倾斜液压缸阀芯动作，将高压油输入升降或倾斜液压缸。阀的作用是当系统中油压超过一定值时，使油液从回油管流回油箱。

(4) The hydraulic distribution valve is composed of a valve body, a lifting hydraulic cylinder valve core and an inclined hydraulic cylinder valve core. Its function is to control the action of the valve core of the lifting or tilting hydraulic cylinder through the joystick to input the high-pressure oil into the lifting or tilting hydraulic cylinder according to the needs of the lifting and tilting of the fork. The function of the valve is to make the oil flow from the oil return pipe back to the oil tank when the oil pressure in the system exceeds a certain value.

（5）节流阀，装于升降液压缸的管路中，其作用是油液的流动阻力，当升降液压缸泄压时，保证货叉缓慢下降。

(5) The throttle valve is installed in the pipeline of the lifting hydraulic cylinder. Its function is the flow resistance of the oil. When the lifting hydraulic cylinder releases pressure, it ensures that the fork drops slowly.

6、电气设备

6. Electrical equipment

电气设备由电源，发动机起动系统和点火系统以及叉车照明，信号等用电设备所组成。

The electrical equipment consists of power supply, engine starting system, ignition system, forklift lighting, signal and other electrical equipment.
