In parts of our district we have many long driveways with poor engine access. Our preconnects of 1-3/4 are only 200' and some 250' 2-1/2 lengths. All of our engines have a static load of 800' of 2-1/2 off of the backstep with a wye. We can pull the length of 2-1/2 needed to get us to the front of the structure and we have access to break our 1-3/4 at 150', so get the 2-1/2 to the front and attach the 1-3/4 for attack. Works well, but it takes planning and practice to get it to where it is a viable option and not a cluster.

Both of our pre-connects are 200 ft long though some companies have added another length making them 250ft. The loads that come off of the back of our engines are well suited for extended lead-outs. One bed has 700ft of 2.5" hose with a 250/50 fog pipe...the first 200ft are made into 3 horseshoes of equal length which make the lead out much easier for one or two men to put into service. The other bed has 700 ft of 2.5" hose with a 1 1/4" smoothbore pipe...again the first 200ft is made into 3 horseshoes. The smoothbore pipe is connected to a gated wye which is connected to 100ft of 1 3/4" hose with a 150/ 50 fog pipe. This is a great bed that I personally use 95% of the time. This lead out provides some options...you can lead the 1 3/4" hose into the structure, add a second 1 3/4" line to the wye as a second attack line or break off the wye and use the 2.5" offensively or defensively for big knockdown. It's not pre-connected but with long lead-outs you don't really need a pre-connect because there is additional time for the engineer to manage the line.

也为我们设置非常相似。我们有100'的13/4英寸克利夫兰（Cleveland），由封闭的怀特（Wye）载有300'的300'死负荷。不幸的是，我们就像规范一样，并将所有事物都与200'相关。我们的软管床是这样的：工程师侧的2--200'1 3/4“前连接； 2---200'2 1/2”官员侧的前连接；1000'的5英寸和我们的3“与克利夫兰捆绑包。我一直都没有回答的一个问题是“ 200'标准长度从何而来，为什么它是全国各地的预连接线路的标准长度？”

Our company runs two engines both similar one engine has the added feature of a booster reel for mop up etc., other than that we have two inch and three quarters one being 150' the second being 200'. We have short distances so they don't need to be long. One is set up as the minute man load one is triple packed. The bumper line has 100' preconnected with an additional 50 in the well. As said short reaches from street to front doors however we also have a two hundred foot two and a half flat packed on both. The rear has 1200 - 1500 of five inch ldh with a split bed with two additional bed areas. One has a dead lay of 600' of 3" which then has a high rise pack sitting on top. The high rise pack has at least 50-150 three inch leader line with an additional 150-200' of 1.75" hose which can also be used as a courtyard or alleyway pack. We have trained for both and long lays and the personnel are all adequately trained and proficient in both aspects although we have found a need to modify and adjust as well as continued training.

我在华盛顿特区以外的一个大都会部门工作，我们的新钻机的线条从200'-350'软管床设置为200'1.75''300'1.75“ 1.75”，250'2“，350'2”。1.75英寸的线条配备了TFT全流平滑孔，带有15/16的尖端。这两条线条配备了相同的喷嘴，但有1 1/8英寸的尖端。我们有两个100'2“高层架，15/16”和1 1/8英寸的尖端，以扩展线路或连接到250'3英寸的领导线。我们已经练习了将2英寸线和一个高层架结合到我们的4Man Engine Company的2英寸的700'的一个。最大的是，尖端尺寸必须为15/16，以使其保持在250psi Mark之下。它很棒。它很棒知道我们在不到3分钟的时间内将700'延伸。

两三年前，我们回到了使用静态（死负荷）软管床。我们使用7 7 5 4软管床。七百英尺5英寸LDH;七百英尺3英寸，200英尺2 1/2（光滑骨）连接到五百英尺3英寸；和1个3/4（光滑荷兰）的两百个连接到400英尺3英寸。我们仍然有200'前连接lines also, but we want to use the static load after we pull past the structure and leave room for the truck company.

My 1st-in area is mainly urban with the front doors very close to the curb, but if we run into that unique situationwhere we need more we have 200' of 2 1/2" preconnected off the back with a gated wye attached, so we would pull that and then bring our packed highrise 2" hose for attack off the wye. In one section of the city it is more suburbs and lots of big houses with long front drives/yards. The 3 Engines in that section of the city have longer preconnects, but also on that same 2 1/2" preconnect with the wye, they have a pack of 1 3/4" with a nozzle attached to the wye and ready to go, similar to a detroit load.

在我目前的部门中，我们的所有结构前连接均为1 3/4和2 1/2，我已经开始培训我的船员，如果我们有一些无法到达门口的东西，或者如果我们必须去结构的后部，我们将2 1/2的电源线拉到我们离门约15英尺的地方，并设置了1 3/4高层包装，以从Wye进入结构。
