因为折叠臂随车吊选用多个液压油缸构成相似关节的吊臂衔接组织，使其在完结动作更快，工作的功率也更高。
而直臂随车吊选用的是一套钢丝绳的收放的起升组织，卷筒正转收绳，吊钩上升，回转放绳吊钩降低，其工作功率性对较低。
二、直臂随车吊工作半径更广
在相同的臂长下，直臂随车吊随车吊还能经过放长钢丝钩的方法，扩展工作纵深，而折叠臂随车吊对请求较深的工作不易完结。
三、折叠臂更合适狭隘工作环境
小空间，大物件，折臂随车吊照样能轻松操作
这是由其构造所决议的，折叠臂随车吊更合适在工厂库房等比照狭小的工作环境，而直臂因为其构造所需的发挥空间更大。
四、直臂更易操控笔直起降
直臂简选用钢丝绳的收放的起升组织，能够严格操控吊物的起降，而折叠臂随车吊选用液压油缸，很难操控起吊物的笔直起降。
五、 折叠臂能加装各种辅具
折叠臂随车吊选用液压油缸的设备，构成相似关节臂机械手的设备，能加装空工作平台、工作斗、夹具、吊篮、板叉、高各种抓具、螺旋钻、装轮胎机械手和拔桩器等辅具。因为直臂前端是软性的钢丝绳，很少有见有直臂加装辅具。
六、直臂随车吊操作相对简略
直臂随车吊选用卷筒收放钢丝的起升组织，操作相对简略，而折叠臂随车吊多个液压油缸，完结相似机械手的动作，比照难操作。
七、 折叠臂占用的整车空间更小
折叠臂随车吊占用空间上一望而知，折叠臂随车吊在运货的时分能将整个吊臂缩短在一起，占用空间相对更小，而直臂随车吊，吊臂只能水平放置，车辆在行进的时分占有的空间较大。
八、直臂更易于整车底盘装置
直臂在构造上比照松懈，有利于整车载荷的涣散，并且重心也离装置方位较远，特别是在吊重物的时分，更利于涣散底盘轴荷。
而选用折叠臂的随车吊，无论是中置仍是后置，因为其构造上比照会集，重心简略会集在底盘的某一轴上，通常某一桥上产生较大负荷，不利于整车的装置。
九、折叠臂报价相对直臂较高
折叠臂随车吊构造相对较杂乱，精度上也H

Product technical parameters of model HCS300A - 4 maximum lifting torque (300 kN. M) maximum lifting weight (kg) 12000 telescopic crane boom section number 4 maximum work rate (m) 16.4 maximum lifting height (m), 17.5 (from the mounting surface) of the crane luffing Angle (°) for the turning Angle of 0 ~ 75 (360 °) rotary rotary speed is 2.5 r/min rated pressure (MPa) 25 rated flow (L/min) to 63 crane weight (kg) 4500 equipped with chassis total mass 1. The folding arm works with the truck crane with higher power
Because the folding arm crane adopts multiple hydraulic cylinders to form the connecting organization of the lifting arm with similar joints, it can move faster in the end and work with higher power.
And the straight arm crane is selected is a set of steel wire rope retraction and placement of lifting organization, reel positive rotation retraction rope, lifting hook up, rotary lowering rope hook, its work rate is lower.
Second, the working radius of the straight arm crane is wider
Under the same arm length, the straight arm truck crane can also extend the working depth through the method of putting long steel wire hook, while the folding arm truck crane is not easy to finish the work that requires more depth.
Three, folding arm more suitable for narrow working environment
Small space, large objects, folding arm with truck crane can be easily operated
This is determined by its structure. The folding arm is more suitable for working in the factory warehouse and so on compared with the narrow working environment, while the straight arm needs more space to play because of its structure.
4. Straight arms are easier to handle
The straight arm is made of the hoisting organization of steel wire rope, which can strictly control the lifting and landing of the lifting objects, while the folding arm is made of hydraulic cylinder, which makes it difficult to control the straight lifting and landing of the lifting objects.
Five, folding arm can add a variety of auxiliary equipment
The folding arm truck crane adopts the equipment of hydraulic cylinder to form the equipment of similar joint arm and manipulator, which can be equipped with the auxiliary equipment such as empty working platform, working bucket, clamp, hanging basket, plate and fork, various grasping tools, auger, tire mounting manipulator and pile extractor. Because the front end of the straight arm is a soft wire rope, rarely see a straight arm with auxiliary equipment.
Six, straight arm crane operation is relatively brief
The straight arm crane adopts the hoisting organization of winding and putting steel wire, and the operation is relatively simple, while the folding arm crane with several hydraulic cylinders, the end of the action of similar manipulator, compared with difficult operation.
Seven, folding arms take up less space
It is obvious that folding arm with car crane takes up space, folding arm with car crane in freight time can shorten the whole boom together, take up less space, and straight arm with car crane, the boom can only be placed horizontally, the car in the travel of time occupies a larger space.
Eight, the straight arm is easier to complete vehicle chassis device
The straight arm in the structure compared with lax, is conducive to the complete vehicle load lax, and the center of gravity is also far from the device orientation, especially in lifting heavy weight, more conducive to lax chassis shaft load.
And choose the folding arm of the truck crane, whether it is still the rear, because of its structure by comparison, the center of gravity is a brief focus on the chassis of a shaft, usually a bridge to produce a larger load, not good for the whole vehicle device.
Folding arm quotation is relatively higher than the straight arm
Folding arm crane structure is relatively messy, the accuracy of the request is higher, the overall production cost quotation is relatively high, the straight arm structure is relatively brief, the production accuracy request is also relatively low, the overall cost is relatively low.
请求更高，制作本钱报价上整体也相对较高，直臂构造相对简略，制作精度请求也相对较低，整体本钱相对较低。
