安徽生产吊机厂家履带吊型号及价格

1、履带式起重机是用履带行走的，所以其行驶的道路坚实可靠。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。 　　
2、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，机上操作与机下指挥一致。

济宁履带式起重机别名履带吊汽车吊由行走机构、回转机构、机身及起重臂等部分组成 16吨履带吊配豪华驾驶室 配16吨滑车 8吨副钩 基本臂7米 臂长23.5。
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，设有两套滑轮组(起重及变幅滑轮组)，钢丝绳通过起重臂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。
履带式起重机的缺点是稳定性较差，不应超负荷吊装，行驶速度慢且履带易损坏路面，因而，转移时多用平板拖车装运。
履带式起重机由吊钩、起重臂、转台、底盘、配重、动力装置、传动机构、工作机构、控制装置等组成。
(1) 吊钩：履带式起重机的取物装置。
(2) 起重臂：桁架式结构，用于支撑起升钢丝绳、滑轮组的钢结构。
(3) 转台：通过回转支撑安装在底盘上，在起重作业时可以回转。
(4) 底盘：包括行走机构和行走装置，可在负重条件下行走。
(5) 配重：安装在起重机回转平台尾部，确保起重机工作平稳。
(6) 动力装置：即动力源，为起重机提供驱动力。
(7) 传动机构：将动力传递给各个工作机构。
(8) 工作机构：包括卷扬机构、变幅机构、回转机构等。
(9)控制装置：用来控制和操纵履带式起重机，实现行走、吊装作业。
安全操作
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.

Crawler crane is the disadvantage of poor stability, should not overload lifting, slow speed and track easy to damage the road surface, therefore, when the transfer of flatbed trailer loading.

The crawler crane is composed of a hook, a lifting boom, a turntable, a chassis, a counterweight, a power plant, a transmission mechanism, a working mechanism and a control device.

(1) lifting hook: the retrieving device of crawler crane.

(2) lifting boom: truss structure, used to support the steel structure of lifting wire rope and pulley block.

(3) turntable: it is installed on the chassis through the rotary support, and can be rotated during lifting operation.

(4) chassis: including a walking mechanism and a walking device, it can walk under load conditions.

(5) counterweight: it is installed at the end of the slewing platform of the crane to ensure the crane works smoothly.

(6) power device: namely power source, providing driving force for the crane.

(7) transmission mechanism: transfer power to each working mechanism.

(8) working mechanism: including hoisting mechanism, amplitude changing mechanism, rotary mechanism, etc.

(9) control device: it is used to control and manipulate the crawler crane to achieve walking and hoisting operations.

Safe operation
