Special Vehicle include Truck Mounted Crane , Aerail work platform , Wrecker truck , Fire fighting truck .
Truck mounted crane is also named Truck Crane , which is a kind of transportation vehicle which is combined with the truck crane and the chassis. It is composed of a jib, turntable, frame, legs etc.. By luffing, rotary, telescopic, hoist mechanism of action to achieve truck crane mechanical action, through a combination of different actions to achieve the lifting operation.
Aerail work platform is also named Aerial Work Truck , Overhead Working Truck, Platform Lifting Truck, which is widely used in electric power, advertising, municipal, garden, communications, airports,building (repair) ships, street lamps, transportation, photography and other aerial work areas. Welcome to our company to purchase the high-altitude operation truck.
Wrecker Truck is also named Wrecker Towing Truck, Tow Rescue Truck .
1. Wrecker use their characteristics can be divided into class carriage, lifting traction class.
Fire Truck is also named fire fighting truck, water tank fire truck, fire-extinguishing water tanker etc.
Modern fire engines usually equipped with ladders, water gun, portable fire extinguishers, self-contained, door clothing, rescue tools, first aid kits and other equipment, the part will be equipped with water tank, a water pump, foam fire extinguishing device and other large fire equipment. In most parts of the fire truck appearance is red, but there are also parts of the fire truck appearance is yellow, part of the special fire truck is also true, at the top of the fire truck usually has alarm sirens, lights and flashing lights. On the roof of a siren and flashing lights.

The blue sky high-grade CNC system is used to replace the imported control system to realize seven-axis servo control (X, Y, Z, A1, A2, B, S) and five-axis linkage control (X, Y, Z, A, B).
Using CNC system integrated programming technology (SIPROM) to develop logic software for automatic tool change (ATC), automatic exchange workbench (APC) and other machine tool auxiliary operations, to achieve random exchange of 60 knives, and three-station work surface 1000mm × 1000mm Any call to the tray.
The technical update of the process characteristics of BMC-10B(5) is carried out to realize the synchronous control of the table turning axis (A axis): the symmetrical gear transmission structure is adopted, and the double servo system (ie A1 axis and A2 axis) is accurately synchronized by CNC. control.
Because the three linear axis servo motors of X, Y and Z are directly connected with the lead screw, the stroke length is 1500mm for X stroke, 1500mm for Y stroke and 1250mm for Z stroke. The actual machining requires high rapid traverse speed and large cutting load. The original KOLLMORGEN BDS3 amplifier and GOLDLINE AC servo motor are used to replace the original Yaskawa DC servo system. At the same time, due to the large spindle power (22kW), the three-stage shift (4 ~ 4000r / min), the spindle speed control system is retained.
Temperature compensation: temperature difference compensation between the main shaft and the column ensures the need for high-precision machining.
The full stroke correction of the three linear axes of X, Y and Z is realized, and the laser interferometer is used for detection. The X, Y and Z axis positioning accuracy and the repeat positioning accuracy are in the micrometer level, and the machine tool precision is improved.
The newly-reformed BMC-10B(5) five-coordinate machining center is a second-hand equipment, one for $400,000, and the renovation fee is about 15% of the purchase price. The key components of the aircraft engine are worth several hundred thousand yuan. Therefore, the value ratio of the machine tool for transformation and transformation is small, and the ratio of production value of the machine tool is smaller.
After the successful transformation of BMC-10B(5) five-coordinate machining center, it has been used for nearly 2 years, which has enabled us to revitalize corporate assets and achieved good economic benefits. On the one hand, it has tapped the potential of the original machine tool, solved some technical problems, improved the technical grade and competitiveness of the equipment; on the other hand, it has made us have a deep understanding of modern CNC technology, so that the transformation has achieved good economic benefits. And social benefits. Source: Yang Zhenhui, Excellent Processing Center of Shenyang Liming Engine Manufacturing Company
2. Wrecker truck is generally widely used in road, factories, construction sites and other large-scale location of production.
3. It's the ideal choice for road management department and the illegal vehicles department and emergency rescue.
4.This wrecker truck can be equipped with a crane to load or unload and install, especially for the wild lifting at railway stations, wharfs, warehouses, construction sites and other narrowly working places.
Fire truck, also known as fire engines, refer to special vehicles used to perform fire fighting tasks. The fire department in most countries of the world will also use it for other emergency rescue purposes.
Fire engines can transport firefighters arrived at the scene of the disaster, and to provide a variety of tools for the implementation of disaster relief tasks.
Fire truck is equipped with a variety of fire equipment, fire fighting equipment of all types of fire vehicles in general, the main tool of the fire brigade and the fire fight, is the most basic of mobile fire equipment common types of fire engines including tank fire engines, foam fire truck, fire pumper, aerial platform fire truck, ladder fire trucks and other.
Brief introduction of numerical control technology transformation method of five-axis linkage machining center
BMC—10B(5) Five-axis machining center is a foreign product in the mid-1980s. It is a machine tool introduced by our company from COMMONWEALTH Aviation Co., Ltd. in Australia in the 1990s. Due to long-term full-load operation, the original imported CNC system components are aging and damaged, and the machine tool can not operate, which affects the production of foreign subcontracting processing and defense of a new machine. In cooperation with the National Engineering Research Center of High-end CNC, we implemented the following CNC technology transformation for BMC-10B(5).
