履带式起重机是用履带行走的，所以其行驶的道路必须坚实可靠。履带式起重机在行走时，其两侧的履带不能一边高一边低，同时也不能停留在斜坡上作业。
履带式起重机在吊装作业时，应注意不能超载吊，不能斜吊。并且履带式起重机在吊起重物时，一般是不能够行走的，如果需要可短距离的行走。并且吊起的重物距离地面越高，操作员越要谨慎操作起重机，使其缓慢行走。并且工作人员也要拉好构件上的溜绳，防止吊物在空中来回摆动出现意外。
3、履带式起重机的起重能力比其他类型的起重机都要大很多。在起重作业中也经常遇到两台履带式起重机同时吊运一个重物，这就是所谓的双机抬吊。由于起吊重物的重量大，所以一定要慎重选择不同吨位的履带式起重机，合理分配主吊和溜尾吊。在起重机施工作业中，指挥员一定要指挥明确，保证机上操作与机下指挥一致。
1, crawler crane is a crawler walking, so its road must be solid and reliable. Crawler crane walking, its two sides of the crawler can not be high and low at the same time can not stay on the slope of the operation.
2, crawler crane in the lifting operation, should pay attention to not overload lifting, not inclined lifting. And crawler crane in lifting heavy objects, it is generally not able to walk, if need to be able to walk a short distance. And the higher the lifting weight is from the ground, the more careful the operator is to operate the crane and make it move slowly. And the staff also want to pull the slip rope on the component, to prevent the lifting object swinging back and forth in the air accident.
3, crawler crane lifting capacity than other types of cranes are much larger. In the lifting operation also often encountered two crawler cranes lifting a heavy load at the same time, this is the so-called two-machine lifting. Due to the heavy lifting weight, so we must carefully choose different tonnage of crawler crane, reasonable distribution of the main crane and the tail crane. In crane construction work, the commander must be clear command, ensure that the aircraft operation and the aircraft under the command of the same.
The crawler crane consists of a walking mechanism, a slewing mechanism, a fuselage and a lifting boom.
The walking mechanism is two chain tracks; Slewing mechanism is mounted on the chassis turntable and restore the fuselage can be 360 °. The lower end of the boom is hinged on the fuselage and rotates randomly. There are two sets of pulley block (hoisting and amplitude changing pulley block) on the top of the boom. The steel wire rope is connected to the winch inside the fuselage through the top pulley block of the boom.
The crawler crane operates flexibly. It is easy to use and has a large lifting capacity. It can also walk on a flat and solid road with loads. After changing the working device, it can become a backhoe or a pile driver. However, the crawler crane is slow and destructive to the road surface.
Selection mainly depends on the lifting weight, working radius and lifting height, often called "lifting three elements", between the three elements, there is mutual restriction. The expression of its technical performance, usually used lifting performance curve or lifting performance corresponding figure table.
Crawler crane is characterized by flexible operation, itself can turn 360 degrees, can load driving on flat and solid ground. Due to the role of the crawler, can work on the soft, muddy ground, and can drive in the rugged field. Crawler cranes are widely used in the construction of prefabricated structures, especially in the installation of single-storey industrial plant structures
履带式起重机由行走机构、回转机构、机身及起重臂等部分组成。
行走机构为两条链式履带；回转机构为装在底盘上的转盘，使机身可回转360°。起重臂下端铰接于机身上，随机身回转，顶端设有两套滑轮组(起重及变幅滑轮组)，钢丝绳通过起重臂顶端滑轮组连接到机身内的卷扬机上，起重臂可分节制作并接长。
履带式起重机操作灵活。使用方便，有较大的起重能力，在平坦坚实的道路上还可负载行走，更换工作装置后可成为挖土机或打桩机，是一种多功能机械。但履带式起重机行走速度慢，对路面破坏性大，在进行长距离转移时，应用平板拖车或铁路平板车运输。
选用时主要取决于起重量、工作半径和起吊高度，常称“起重三要素”，起重三要素之间，存在着相互制约的关系。其技术性能的表达方式，通常采用起重性能曲线图或起重性能对应数字表。
履带式起重机的特点是操纵灵活，本身能回转360度 ，在平坦坚实的地面上能负荷行驶。由于履带的作用，可在松软、泥泞的地面上作业，且可以在崎岖不平的场地行驶。在装配式结构施工中，特别是单层工业厂房结构安装中，履带式起重机得到广泛的使用。
