Understanding the classification, advantages, and disadvantages of car cranes is the first step to fully understanding the car crane. First of all, let's take a look at the major categories of car cranes. 1, according to the boom system classification: a. Truss lift arm (fixed truss arm and variable truss arm) b. Hydraulic telescopic arm 2, according to the transmission system classification a, mechanical transmission type b, hydraulic transmission type c. Power transmission type d, power - hydraulic transmission 3, according to the weight classification a. Small weight up to 15t is small b. Medium weight from 16-25t c. Large-scale lifting capacity above 26t Let’s take a look at the major components of the car crane. 1. The car cranes in the small tonnage of the walk-off part (known as the chassis) generally use the standard truck chassis, while the large and medium-sized tonnage truck cranes use the special-purpose automobile chassis. 2, slewing bearing part. It is a device that is mounted on the undercarriage and is used to support the upper slewing portion. It supports various loads of the turning part of the getting on car through the support wheel or roller to the undercarriage of the undercarriage, so as to keep the turning part of the upper car rotating correctly and flexibly around the axis of rotation and ensure that there is enough turning part of the upper car. Stability. 3, on the turning part of the car (also known as rotary machine). The rotary machine platform is equipped with lifting devices, luffing mechanisms, rotary machine operating room and other devices. The automobile crane has good mobility and flexibility, can be rapidly transferred from one work place to another, and the preparation time required for the transfer and input work is very short, and the utilization rate of the crane can be more fully improved. Truck cranes are widely used in the loading and unloading of building sites, open freight yards, warehouses, railway stations, docks, workshops, and other places. They are also used in hydropower projects to pour the bottom concrete of hydraulic structures. They are also particularly suitable for work sites. Decentralized, sporadic handling and installation of goods. The disadvantage of the automobile crane is that during the operation, better road conditions must be required, and when the hoisting operation is performed, the legs are almost to be put down, thereby limiting the range of activities of the crane during the hoisting operation. The Warning Triangles is a passive reflective item which is made of plastic reflective material. It can be folded and easy to carry! It's the necessary item for each vehicle! Each vehicle must carry the Warning Triangles, so as to encounter sudden failures. When we stop the vehicle and repair, we need to put the Safety Warning Triangle 50 meters before and after the car, which can remind other vehicles to pay attention.
