1. Hello, landlord. I'm Yin Xijian from Guangming crane. I've calculated the price for you. Liang is 51700.00, and the gourd is about 18000.00. In this case, the price of the equipment is more than 69700. It can't be calculated according to the installation, because the installation usually includes track, safety sliding line, etc.
I hope it can help you
I hope it can help you
2. The counterfeiters are all smart in the end, but they are mistaken by smart. Watch it
3. Our factory is cheaper. A few days ago, it was because of the quality. A car missed welding 3cm, the whole plant from top to bottom. He was fined. Now the quality is up!! It depends on the tonnage you want. QY8A/ 8FN/ QY12A/12C/12G QY/20A TC200 Tc200 is a new proct. It's only finished today. It's not loaded yet. You can't buy it. QY25. Qy25n / qy25n5 tc250. And qy35. Qy50 tc500, and qy70. The heavier the price, the more expensive. I suggest buying a model of less than 50 tons. Except for 35. Because I didn't weld it.!! Recommend the latest tc200, worthy of attention. Everyone did it perfectly
Anhui. Liugong crane. limited company!!
Anhui. Liugong crane. limited company!!
4. Yes, in this case, it belongs to the safe lifting range.
5. Second hand beams, new explosion-proof motors and electrical appliances can be considered

7. Hey, hey... It's you again! SpongeBob
this is a good solution. You don't need to make such a long-span girder, but according to the objects you drop, you can make a small gantry crane. Instead of walking on the track, you can directly use the universal wheel as the wheel, and you can push and run everywhere (provided that there are no obstacles in your field, and the field should be flat). You can make a 1-ton chain hoist on it and do it all! Specific you can give me Q message, it seems that I added to you

8. The bridge crane is a kind of lifting equipment which is mounted horizontally over the workshop, warehouse and stockyard to lift materials. Because its two ends are located on tall concrete columns or metal supports, and its shape is like a bridge, it is also called "crane" or "traveling crane"
the bridge of the bridge crane runs longitudinally along the track laid on both sides of the viact, and the lifting trolley runs horizontally along the track laid on the bridge, forming a rectangular working range, which can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and the largest number of lifting machinery. Bridge crane can be divided into ordinary bridge crane, simple beam bridge crane and metallurgical bridge crane
ordinary bridge crane is generally composed of lifting trolley, bridge running mechanism and bridge metal structure. The trolley is composed of lifting mechanism, trolley running mechanism and trolley frame
the lifting mechanism includes motor, brake, recer, drum and pulley block. The motor drives the drum to rotate through the recer, so that the wire rope can be wound on the drum or put down from the drum to lift the weight. Trolley frame is a frame which supports and installs lifting mechanism and trolley running mechanism. It is usually a welded structure
the driving modes of crane running mechanism can be divided into two categories: one is centralized driving, that is, driving the driving wheels on both sides with a long driving shaft driven by a motor; The other is separately driven, that is, the driving wheels on both sides are driven by a motor. The "three in one" driving mode of brake, recer and motor is widely used in small and medium-sized bridge cranes. The universal coupling is often used in the driving device of ordinary bridge cranes with large lifting capacity for easy installation and adjustment
generally, the crane running mechanism only uses four driving and driven wheels. If the lifting capacity is large, the wheel pressure is usually reced by adding wheels. When there are more than four wheels, the articulated balanced frame device must be used to make the load of the crane evenly distributed on each wheel
the metal structure of bridge is composed of main beam and end beam, which can be divided into single beam bridge and double beam bridge. The single girder bridge is composed of a single girder and end beams on both sides of the span, while the double girder bridge is composed of two girders and end beams
the main beam is rigidly connected with the end beam, and wheels are installed at both ends of the end beam to support the bridge running on the viact. The main girder is welded with rails for the operation of the trolley. There are many structural types of bridge girder, such as box structure, four truss structure and vierendeel truss structure
box structure can be divided into normal track box double girder, partial track box double girder, partial track box single girder and so on. The main beam is composed of upper and lower flange plates and vertical webs on both sides. The trolley rail is arranged on the center line of the upper flange plate. Its structure is simple and easy to manufacture. It is suitable for mass proction, but its weight is large
the cross sections of double box girder and single box girder are composed of upper and lower flange plates and main and auxiliary webs with different thickness. The trolley rail is arranged above the main webs, and the short stiffening plate in the box can be omitted. The single box girder of partial rail is composed of a wide flange box girder instead of two main girders, which has less dead weight but more complex manufacturing
the four truss structure is composed of four plane trusses to form a closed space structure. The upper horizontal truss surface is generally paved with walking board, which has light weight and high stiffness. However, compared with other structures, it has large size, complex manufacturing, low fatigue strength and less proction
the vierendeel truss structure is similar to the partial rail box girder, which consists of four steel plates to form a closed structure. Except that the main web plate is a solid web I-beam, the other three steel plates are cut into many windows according to the design requirements to form a vierendeel truss without inclined bars. The upper and lower horizontal truss surfaces are paved with walking boards, and the crane running mechanism and electrical equipment are installed inside the bridge, It is widely used in China because of its light weight and high overall stiffness
the ordinary bridge crane is mainly driven by electricity, which is generally operated in the driver's cab, and also remotely controlled. The lifting capacity can reach 500 tons and the span can reach 60 meters
simple girder bridge crane is also called girder crane. Its structure is similar to ordinary bridge crane, and its lifting capacity, span and working speed are small. The main girder of bridge is a simple section beam composed of I-beam or other section steel and plate steel. The trolley is equipped with chain hoist or electric hoist as a lifting trolley, which generally runs on the lower flange of I-beam. The bridge can run along the track on the viact or the track suspended under the viact. This kind of crane is called suspension beam crane< The basic structure of the bridge crane is similar to that of the ordinary bridge crane, but there are special working mechanisms or devices on the trolley. The working characteristics of this kind of crane are frequent use, bad conditions and high working level. The working principle of bridge crane: (1) characteristics and classification of bridge crane
1. Characteristics of bridge crane:
the crane whose pick-up device is suspended on the trolley or travelling hoist that can run along the bridge is called "bridge crane"
the bridge crane whose two ends of the bridge are directly supported on the elevated track by the running device is called "bridge crane"
bridge crane is generally composed of bridge with crane running mechanism, trolley with lifting mechanism and trolley running mechanism, electrical equipment and cab. It looks like a single span flat slab bridge with two ends supported on two parallel overhead tracks. The lifting mechanism is used to lift the goods vertically, and the lifting trolley is used to carry the load for lateral movement; The bridge and crane running mechanism are used to move the trolley and goods longitudinally, so as to form a three-dimensional space within the span and the specified height for handling and loading and unloading goods
bridge crane is the most widely used and has the largest amount of rail running crane, and its rated lifting capacity ranges from several tons to several hundred tons. The most basic form is the general hook bridge crane, other forms of bridge cranes are basically derived from the general hook bridge< (1) general bridge crane
general bridge crane refers to the general purpose bridge crane working in general environment (see standard GB / t14405-93). The following types of cranes are general purpose overhead cranes
① general hook bridge crane
the general hook bridge crane is composed of metal structure, crane running mechanism, trolley running mechanism, lifting mechanism, electrical and control system and cab. The pick-up device is hook. If the rated lifting capacity is less than 10t, there is usually one lifting mechanism; For those above 16t, there are two main and auxiliary hoisting mechanisms. This kind of crane can load, unload and transport materials and equipment in a variety of working environments
② grab bridge crane
the device of grab bridge crane is grab, and wire rope is used to connect grab lifting, lifting mechanism and opening and closing mechanism respectively. It is mainly used for loading, unloading and lifting of bulk cargo, waste steel and wood. In addition to the hoisting and closing mechanism, the structural components of the crane are the same as those of the general hook bridge crane
③ electromagnetic bridge crane
the basic structure of electromagnetic bridge crane is the same as that of hook bridge crane, but the difference is that a DC lifting electromagnet (also known as electromagnetic sucker) is hung on the hook to lift magnetic ferrous metal and its procts. Usually, the AC power supply is changed into DC power supply through the electric generator set on the bridge walking platform or the thyristor DC box installed in the cab, and then the DC power supply is sent to the lifting electromagnet with flexible cable through the special cable reel on the trolley frame< There are three types of al-purpose bridge cranes: grab hook bridge crane, electromagnetic hook bridge crane and grab electromagnetic bridge crane. It is characterized by two sets of independent lifting mechanisms on one trolley, one for grab and one for hook (or one for electromagnetic sucker, one for hook, one for grab and one for electromagnetic sucker)< Three purpose bridge crane is a kind of multi-purpose crane. Its basic structure is the same as the electromagnetic bridge crane. According to the needs, it can use the hook to lift heavy objects, or hang a motor grab on the hook to load and unload materials, or unload the grab and then hang an electromagnetic disk to lift ferrous metals, so it is called three purpose bridge crane
grab * AC power supply works, electromagnetic disk * DC power supply works. Therefore, this type of crane must be equipped with electric generator set or SCR DC power box just like the electromagnetic bridge crane. This kind of crane is suitable for the material place where the pick-up device is often changed< (6) double trolley bridge crane
this kind of crane is basically the same as the hook bridge crane, except that two trolley with the same lifting capacity are installed on the bridge. This machine is used to lift and load long objects. The bridge crane uses the traditional winding motor rotor series resistance speed regulation mode to control the start stop and running speed of each mechanism on the crane. The hoisting mechanism of the bridge crane controls the forward and reverse rotation of the three-phase asynchronous motor, and drives the drum with wire rope through the coupling and recer to raise or lower the hook. The two moving mechanisms of the bridge crane drive the wheels to rotate through the coupling and recer by controlling the forward and reverse rotation of the three-phase asynchronous motor.
the bridge of the bridge crane runs longitudinally along the track laid on both sides of the viact, and the lifting trolley runs horizontally along the track laid on the bridge, forming a rectangular working range, which can make full use of the space under the bridge to lift materials without being hindered by ground equipment.
