How do you choose single girder or double girder for gantry crane?
Azeus Crane Co., Ltd: In general, the lifting weight under 50 t and the span within the 35 m, it is appropriate to choose the single girder crane without other special requirements. If the requirements of wide leg width , high working speed, or lifting heavy, long and great things frequently, it's better to choose double girder gantry crane.
What is price of container gantry crane?
In general, quotation for gantry crane by manufacturer originates from factors as following1. Lifting capacity of the gantry crane.Lifting capacity of the gantry crane can decide directly the overall structure, accessories, type of main beam and etc. Lifting capacity is the most important element for the price of the gantry crane. For example, if the gantry crane is in small lifting capacity, it will adopt truss girder or honeycomb girder. And heavy duty gantry crane is always in box girder. The accessories, such as winch, steel wire rope can also be influenced by lifting capacity of the gantry crane.2. Lifting height of the gantry crane.It has been acknowledged that the higher lifting height, the larger span and the more steel.3. Span of the gantry crane.It has obvious influence for the price of gantry crane. If the span of the gantry crane is in large, there will be more strength for the main girder of the gantry crane, so that the deflection of the main girder can be controlled well.4. Working group of the gantry crane.Working condition can decide working group of the gantry crane. For example, gantry cranes for lifting bridge girders in precast yard is always not used frequently, they can be classified into A3 working group. If gantry crane is working in freight yard or workshop, they will be in high using frequency, even explosion protection is needed if necessary. Therefore, the working group of these gantry crane will be classified into A4 and more higher. Different groups have obvious price difference.5. Price of raw material.Gantry crane is welded and assembled by steel, so the price of steel also has an effect on the price of the gantry crane.Established in 1992, Our company ------- Zhengzhou Huazhong Consturction Machinery Co., Ltd.

Why does honeycomb girder gantry crane have a potential market?
Zhengzhou Huazhong Construction Machinery Co., Ltd. (ZZHZ). Thanks for asking the question about honeycomb girder on Answers, because it is one of our patents. Honeycomb girder developed for gantry crane and bridge girder launcher by our company -----Zhengzhou Huazhong Constrution Machinery Co., Ltd ( short for ZZHZ ), which is a new type of main girder and has been widely used in crane fields. The reason why increasing people are looking for honeycomb girder type cranes because they are unique and reliable.Brief introduction on honeycomb girder gantry crane and bridge girder launcher are as following.1. Why we called it honeycomb girder?The main girder is honeycomb girder.For honeycomb girder, it means many hexagonal holes which looks like honeycombs in the main girder, with which the air current could pass through the hole when the launcher works high above the ground. Then it greatly reduces wind impact on the gantry crane, so it is quite safe.2. What are Advantages of honeycomb girder?a. compared with truss girder, safer!Steel plate welded with steel plate (honeycomb girder) is safer than point to point welding (truss girder). If there is an occasional bad welding, the honeycomb girder will not be affected too much, while if it happens on truss girder crane, the whole girder may lose stability and cause an accident.b. Compared with box girder, safer!When box girder crane works high above the ground, the heavy wind will have a great impact on it and make it unsafe. While the honeycomb girder launching gantry has reasonable design(honeycomb hole) to reduce wind impact. Besides, it has a light self weight and cost lower.3. Featuresa. quite safeb. high wind-resistance, high stiffness and low deflectionc. light self weightd. flexible legse. unique and reliable pin connection, easy installation and disassemblyf. high quality imported electrical elements are used4. LimitationAt present, if material to be lifted is less than 250t, a honeycomb girder can be used.Generally speaking, with its own characteristics, the new style honeycomb type gantry crane and bridge girder launcher from ZZHZ will be the flavor of the market.Please find more information about honeycomb girder on website of Zhengzhou Huazhong Construction Machinery Co.,Ltd.
What is a overhead bridge crane?
Gantry cranes are a type of crane built atop a gantry, which is a structure used to straddle an object or workspace. They are also called portal cranes, the "portal" being the empty space straddled by the gantry. Dgcrane is professional material handling equipment manufacturer and servicer with largest production in global. Provide you with overhead crane, gantry crane, electric hoist, etc. of safe, reliable and efficient crane solutions and services.Welcome to inquiry dgcrane. The terms gantry crane and overhead crane are often used interchangeably, as both types of crane straddle their workload. The usual distinction drawn between the two is that with gantry cranes, the entire structure is usually wheeled. By contrast, the supporting structure of an overhead crane is fixed in location, often in the form of the walls or ceiling of a building, to which is attached a movable hoist running overhead along a rail or beam. Further confusing the issue is that gantry cranes may also incorporate a movable beam-mounted hoist in addition to the entire structure being wheeled, and some overhead cranes are suspended from a freestanding gantry.
What is permissible limit for vibrations in gantry girder of crane and are there any proven methods to reduce the vibrations?
Please ask only one question at a time. See the related questions.
What is single girder and double girder EOT cranes?
Based on CMAA (Crane Manufacturers Association Of America) specifications, both single & double girder are equally rigid, strong & durable. This is because single girder cranes use much stronger cross girders than double girder cranes, and single girder cranes have lateral bracing, unlike double girder cranes.

What is the notice during the operation of MG Double Girder Gantry Crane?
Azeus Crane Co., Ltd: 1.The normal environment temperature of the crane is between -25℃ to +40℃, the average temperature of the whole day can not exceed the 35℃. 2. The altitude of Installation site is within 2000m. The motor capacity should be checked if the altitude is more than 1000m.
Why inefficient braking create in Double Girder Electric overhead travelling crane?
Due to double girder the load of hoist is carried by two beams, so inefficient braking takes placd
