3,electric oven power into line to install before 150 (A) amp,connect the power supply air switch wire section area should be the sectional not less than 16 square millimeter of rubber wire set more than copper-core,shell to reliable grounding.The power supply voltage may not have large fluctuations.
4,waste gas emissions to the discharge of gases connected to the outside,in the pipeline to link with metal pipe to avoid accidents.
5,all ready to have the correct sequence,check on trial,close the switch,first press "always stop (a)" switch,and press down the power button on the control board,the corresponding indicator,and then starting,then respectively operation panel of buttons and switch on relevant for the corresponding operation,when need emergency stop or long-term out of service,please press the abrupt stop button can be emergency stop.
6 before operation,the setting:each instrument switch after electrify to set up.Turn the knob electronic temperature controllers set,the working temperature,time to adjust to the instrument of the green light to cake,for example,a temperature of about 180 ℃,electronic timer for the time setting for 30 minutes.
7 and closed door,press the start switch and the clockwise turn drum wind switch,electric heater,and start heating furnace heated air supply.First installed after the start,attention should be paid to see after the blower rotation direction and out the size of the air,roast the car to a clockwise turn,the air is larger,and should be the air volume small,if long time reverse rotation,chassis furnace experience severe fever,heating furnace is slow,long time will be destroyed,the machine will please pay close attention to the user.A reversal,or against the wind will only when the three phase power line of arbitrary two exchange connection over only.
When hot air taxiing,electronic temperature control instrument furnace temperature display started,when the temperature rise to temperature control instrument on the set value,heater automatically stop heating,(combustion machine stop work) when furnace temperature below the setting,heater and will be automatically enabled barriers to oven heated,so the temperature constant circulation,in value.Specific baking temperature by the baked food to decide.
8,when the temperature reached the set value,then open the door,the door with automatic interlocking function,in the open door,drum wind and heating stop immediately,and at the same time frame,only to stop rotating also shut door to normal starting heating.The already cheng fang good pan cart type grill,a hook type in pushing charging the oven shall be baked car pushed off,push the lower top hook positioning clip,(turn disc without hook,directly will push on the merry-go-round,roast car can) sure grill already in place,with correct closed door,turn rotary switches can be baked food.
9,in the roasting process,open "lighting" switch,can be seen clearly the baking process.(note:don't need to look at,please turn off the light,so that can prolong the service life of the floodlight.)
10 and the uniformity of air conditioning is a do work,the correctness of the adjustment will directly affect the color of baked goods and quality,should pass DuoCi adjust to achieve the ideal effect.The adjustment of the specific methods:the size of the outlet according to the colour and lustre of the food on the adjustment.The high temperature,such as the upper grill food color deep,at this time the outlet shall be on the adjustment plate to close,use among with reduced the outlet air away up,up,down,six of the boards,according to the baked food the colour and lustre of fine adjustment can get on the ideal effect.
11,the oven with a wet function,when installation should be on the top of the furnace in water inlet in again.When the baked food need to add wet when baking,click on the control panel humidifying button,this time the inlet valve automatically open to spray water by hot air furnace,formed from the outlet,evaporation moisture,make the furnace blew out maintain humidity.Humidity by users according to the size of the wet switch with the length of time ordered.

没问题,熟能生巧贝.

是的.朋友.
在作业的不同来决定自己的使用强度.
如果强度比较大还是租赁比较合算的.

1,1吨的约,2吨左右；
2,2吨的,3.5吨左右；
3,3吨的,4.3吨左右.
4,5吨的,7吨左右；
5,6吨的,8,3吨左右；
6,7吨的.9.5吨左右.

两样都有电动的是近口的要20多万,机动的国产10万左右

叉车 宽1.25 长2.8米不算叉子 高2.1米

We place cartons vertically on pallets.Although those cartions are wrapped with plastic bags,they still lean to one side once forklift touches the pallet.Pallets are stacked one above the other in container,therefore goods would be injured by the heavy weight pressed on.
最后一句我改为：货物会因压在其上面的沉重重量而损坏 ,意思是一样的

30 30 30 30 字少了回答不上

我给你通俗的解释一下吧,更深层的理论要多学习多实践,一会也不可能说清楚的.
1.如果用电压表测得充完电（断开电源）的蓄电池,电压只有1.2或1.3,你举的例子是总电压3V,那么可以初步确认,应该有部分单体短路的现象（比如极板间隔纸污染而被击穿造成了短路）,如果是0.2V,那基本确认是断路了.
只有部分短路的情况下,用充电机充电,它的电压才可能显示正常.这个你可以理解为有一个木桶有一个洞,如果你不加水,那么它很快漏掉了,你一直在大量加水,它的水面还是满的.
具体的理论解释很麻烦,如果你有兴趣慢慢学习一下吧.
2.充电的时候其实说白了,就是电能转化为化学能.好比你吃饭的时候,食物转化成了你身体里的备用能量,然后你运动的时候再释放出来.
3.放电和充电时相反的,化学能转化为了电能.好比你运动的时候,很快就感觉饿了,因为你通过吃饭来贮藏的能量用完了.

可以改装,改装后只是行走速度变慢,后退只有一档.
但这两种变速箱外型及安装尺寸不同,特别是输入输出轴的位置和连接口不同.因此对叉车改动很大,改装难度大,建议不改装,保持原变速箱.

这个模型其实是计算底板正方形边长1.1M时,求小箱子的边长的最大整数值.
1.设小箱子边长为a*b,假设a>b,
设可摆放每边的长度可摆放边a的是n1,边长b的是n2(单对每边来说)
则取f(n1,n2)=min(1.1-n1*a-n2*b)>0,当f(n1,n2)越接近0时摆放地越紧密.
用1号箱来说,a=0.3 b=0.24,当取n1=2,n2=2时f(n1,n2)=1.1-1.08=0.02
同理2号箱为 n1=1 n2=2
3号箱为 n1=1 n2=4 或n1=3,n2=1

2.可将f(n1,n2)-=min(1.1-n1*a-(n2-1)*b)>0 每边多排列两个半个才不会掉.
即看做1.1+b的正方形

Labor and/or folklift may cause costs,of which the specific service is decided by practical condition of the goods.Contact me if there is any problem.

打个比方说,三吨的标准叉车（没有安装属具,就没有是改侧移一类的改装）,在叉子根起算,五十厘米以内,能承载三吨,五十厘米往外越远起重能力越低,明白没?每个车都不太一样,但都差不多,基本在叉车的操作台上（和仪表盘在一个平台上,应该在右面）,有个承载能力的图表,看那个就行,重心在叉子多远升起多高可以承载多少重量

支持力
未运功.没做功
因为支持力与重力抵消了,这个方向上货物并没有动,所以是未运动,又因为力在这个方向上没有位移,同样是没做功

上图油缸固定在转向主销轴承座的钢板上,受力最好,钢板与转向受力点连在一起,桥体不会变形.
下图油缸固定在转向桥平衡承轴的钢板上,受力不好,钢板通过转向桥方梁与转向受力点连在一起,桥体容易变形.

解题思路：本题要抓住做功的两个必要因素：（1）作用在物体上的力；（2）物体在力的方向上通过的距离；二者缺一不可．

A、叉车举起货物，叉车给货物一个向上的力，货物向上移动了距离，叉车对货物做功，不符合题意．
B、用力推木箱没推动，人给木箱一个水平方向的力，却没有在水平方向移动距离，人对木箱没有做功，符合题意．
C、直升机吊起铁塔，直升机给铁塔一个向上的力，向上移动了距离，直升机对铁塔做功，不符合题意．
D、提着水桶在水平面匀速前进，人给水桶一个向上的力，水桶向上没有移动距离，人对水桶没有做功，符合题意．
故选BD．

点评：
本题考点： 力是否做功的判断．

考点点评： 有力有距离，力对物体不一定做功，物体必须在力的作用下沿力的方向通过了距离，力对物体才做功．

检查,说白了就是保证书,我可以给你一个简单的框架,你自己往里填充.明白我的意思吗?
先是承认自己的错误,然后详细的讲清楚事情发生的经过,然后是保证以后怎么样,需要做到的几点要求.

Some frequently-used parts to be inspected are stored in Area A, for example……. Forklift(s) need(s) to frequently transport the parts to be inspected from Area A to Inspection Area. Because the large variety types of parts in Area A and the distance away from Inspection Area, It wastes a lot of time on finding and transporting the parts.

矢量求和：Vx=0.4m/s
Vy=0.3m/s
V=(Vx²+Vy²)½ =0.5m/s

叉车不能转运钢瓶,因为叉车不是危险品运输车.不知道你的叉车执照是买的还是考的?在叉车七不叉里有这条的.叉车严禁转运钢水,钢瓶,钢包.自己可以去查下.

货叉根角不得大于93°

你看看离合器好不好

C指叉车,P指平衡重式,C指柴油,D为自动挡,30指3吨,HB指该车属于H系列及主配490B发动机,CPCD10N-R 这个型号应该还不全,全的话后面应该还有字母X,W,等用来标示发动机品牌的.

Due to （Because of) the use of longerm high frequency,X1 and X2 often break down,
which need to take a lot of time to repair,and coupled with the aging of the equipment lead to the decline of forklift performance,it impact on the operator's working efficiency seriously

举升1米5左右的,2000-6000都有,当然质量也不一样.
举升2米多、3米的,比1米5的贵几百到一千不等.

We have selected a new our forklift rental company through an auction,whom we have renewed two forklifts rentals of with.The new contract enable us to lower the rental cost and maintenance fee,provide newer and more reliable forklifts,which ultimately increases the efficiency at work.

闲着闲着,给你算一下,柴油叉车的行驶速度最快（油门最大）约28km/h,耗油量约4.5L,4.5L/28KM=0.160714.L*6.97元/L=1.12元/KM

应该是叉车

电动叉753

Because a lot of wood beam were generated during unloading process,the forklift would transport these wood beam to the refuse storage area frequently which leading to the reduction of the work efficiency of the forklift.

是最后一个,由于物体没有发生位移,所以此力没有做功.

Due to the over-narrow space of the location in Bulk A,working space is limited when forklift accessing goods,resulting in damage and low efficiency.

“似水清风”：
叉车能把货物平运、举高、堆垛、转移、装卸……,功能较多,使用灵活.马对原木来说,只能用作拖、拉的平面运输,功能较简单.你说对吗,祝好,再见.

有电瓶指示灯；机油报警灯；液压油报警灯,燃油报警灯,前进后退指示,方向灯指示,近光远光指示灯,还有一个电脑版报警.看符号应该大致可以猜出的.

一般是6分钟计时0.1小时.所以17.6就是17个小时加上6*0.6分钟（17小时36分钟）.
