北京叉车主要技术性能参数有哪些？

说明叉车的结构特征和工作性能的数据称为叉车的技术参数，叉车的技术参数分性能参数、尺寸参数和重量参数三类。
the data describing the structure characteristics and working performance of the forklift is called the technical parameters of the forklift. the technical parameters of the forklift are divided into three categories: performance parameters, dimension parameters and weight parameters.
叉车主要性能参数有：额定起重量、载荷中心距、最大起升高度、自由起升高度、门架倾角、最大起升速度、最高行驶速度、最大爬坡度、最小转变半径、发动机（电机、蓄电池）性能指标等。
the main performance parameters of forklift are: rated lifting capacity, load center distance, maximum lifting height, free lifting height, gantry angle, maximum lifting speed, maximum driving speed, maximum climbing slope, minimum transition radius, engine (motor, battery) performance index, etc.
主要尺寸参数有：外形尺寸（长、宽、高）、轴距、前后轮距、最小离地间隙等。
main dimension parameters include: overall dimension (length, width, height), wheelbase, front and rear wheelbase, minimum ground clearance, etc.
主要重量参数有：自重、空载前轴负荷、空载后轴负荷、满载前轴负荷、满载后轴负荷等。
the main weight parameters are: self weight, no-load front axle load, no-load rear axle load, full load front axle load, full load rear axle load, etc.
1．额定起重量：规定叉车起升货物的最大质量。
1. rated lifting capacity: specifies the maximum mass of goods lifted by forklift.
2．载荷中心距：额定起重量货物的重心至货叉垂直段前表面的距离。以“mm”表示。我国按照不同的额定起重量，规定了相应的载荷中心距，以此作为基准值。
2. load center distance: the distance from the center of gravity of the rated lifting cargo to the front surface of the fork vertical section. in mm. according to different rated lifting capacity, the corresponding load center distance is specified in china, which is taken as the reference value.
3．额定起重量时的最大起升高度：在额定起重量下，货叉升至最高位置，门架垂直，由地面至货叉上平面的垂直距离。
3. maximum lifting height under rated lifting capacity: under rated lifting capacity, the fork rises to the highest position, the gantry is vertical, and the vertical distance from the ground to the upper plane of the fork.
4．自由起升高度：在无载状态、门架垂直、门架高度不变条件下起升，货叉上平面至地面最大的垂直距离。
4. free lifting height: the maximum vertical distance from the upper plane of the fork to the ground under the condition of no load, vertical gantry and constant gantry height.
5．门架前倾角、门架后倾角：在无载状态下，门架相对于垂直位置向前或向后的最大倾角。
5. gantry rake angle, gantry caster angle: under no-load condition, the maximum rake angle of gantry relative to vertical position forward or backward.
6．满载、无载最大起升速度：在额定起重量或无载状态下，货叉或属具起升的最大速度。
6. maximum lifting speed under full load or no load: the maximum lifting speed of fork or accessories under rated lifting weight or no load condition.
7．满载、无载最高运行速度：在额定起重量或无载状态下，车辆在乎整坚硬路面上行驶的最高速度。
7. full load and no-load maximum running speed: under rated lifting capacity or no-load condition, the vehicle cares about the maximum speed on the whole hard road.
8．最大爬坡度：车辆在无载或额定起重量状态下，按规定速度稳定行驶时，所能爬越的最大坡度。
8. maximum gradient: the maximum gradient that the vehicle can climb under the condition of no-load or rated lifting capacity, when driving stably at the specified speed.
9．最小转变半径：在无载状态下，车辆向前或向后低速行驶，向左或向右转弯，转向轮处于最大转角时，车体外侧到转弯中心最大的距离。
9. minimum turning radius: the maximum distance from the outside of the vehicle body to the turning center when the vehicle is driving forward or backward at low speed, turning left or right and the steering wheel is at the maximum turning angle under no-load condition.
10．叉车长度：对平衡重式叉车，指叉尖至车体末端的水平距离。
10. forklift length: for counterweight forklift, the horizontal distance from the fork tip to the end of the vehicle body.
11．叉车宽度：叉车两外侧的最大水平距离。
11. forklift width: the maximum horizontal distance between the two sides of the forklift.
12．叉车高度：由地面至叉车顶端的垂直距离。
12. forklift height: the vertical distance from the ground to the top of the forklift.
13．轴距：前、后桥中心线间的水平距离。
13. wheelbase: the horizontal distance between the center lines of front and rear axles.
14．轮距：同一桥左右车轮与地面接触面中心的距离。多个车轮的轮距按中心点处测定。
14. track width: the distance bet
