Electric overhead travelling crane stands for EOT, which is designed to move, lift or transport materials up to 500 ton or even more under custom design service. The big lifting capacity makes the electric overhead travelling bridge crane as the ideal solution for particular demanding task. As the leader overhead electric travelling crane manufacturer, we are quite confident to produce many kinds of electrically operated overhead travelling crane for sale. The electric overhead traveling crane ganrty crane can be divided into five different sections, such as the bridge girders, end carriages, hoisting trolley also called crab, the long travel machinery, and floor operation. Benefit from the high work efficicency and safety, less or zero maintenance and long worklife, cheap price and high quality, the electric travelling crane is used in many place, like the steel factory, grain or sugar factory, warehosue and many building construction sites.
Because different using function and working place, we also offer you several different design about electric overhead travelling crane for sale. Aimed at the different overhead crane structure, we can design single girder and double girder overhead traveling crane. More than 300 professional electric bridge travel crane engineers also design two different electric travelling overhead crane suspension ways, which including the top running electric overhead traveling crane design to adapt in the factory with enough space and height and also the under running electric overhead travelling crane for the warehsoue with limited place. At the same time, we also can design and produce the special electric travelling overhead bridge crane design for hazarous or dangerous working environments where have the risk for explosing. These crane mainly includers the explosion-proof electrically operated overhead travelling crane and metallurgy electric overhead travelling crane gantry crane.
Smart features of European type electric overhead travelling crane
- Adapted the advanced technology of European, our electrical travelling overhead crane are strict control in every production line. All our electric overhead travelling crane for sale and components are produced on the basis of DIN and FEM. A series of free test service will be offer before our customer buying.
- Our motorized electric magnetic overhead cranes is the result of over one century’s hard working and consistent innovation. Compared with the traditional technology, the electrically operated overhead travelling crane is lower with a decrease of around 25% and less with almost 30%, as well as owns lighter wheel pressure and quite small critical distance.
- There are much advantages can be get though a modular design for our overhead electric travelling crane. Such as the richer product assortment, easier installation and transportation, as well as the stable product quality and shorter supply cycle.
- Equipped with so many safety devices, our electric overhead travelling crane for sale holds the most safety. These advanced safety protection includes the monitor system of overload limiter, the self-examine system, limit switch, and imported wire rope from Germany.
- Adopt with advanced technology and electric overhead travelling crane production equipments, European type overhead crane not only enjoys long worklife, but can reach less or almost zero maintenance, which can maxinum cut down spending and earn more money. At the same time, our European model electric overhead travelling crane for sale also have several class work duty that includes A4, A5, A6,A7 to satisfied all the using of our customers.
Nine safety devices on our electric travelling bridge crane
- Moment limiter. A moment limiter is made up of power detector, arm angle detector. When the lifting capacity of electric overhead travelling crane for sale reach rated value, a moment limiter can prevent a magnetic overhead crane from overturned timely though special signal and red light to warn the operator to stop working.
- Position limiter. This device is designed to avoid the arm of electric overhead travelling crane touch winch. When the arm of an electrical travelling overhead crane reach the biggest angle, position limiter can warn the worker by raising the alarm.
- Outreach indicator. Put up an indicator panel on the arm of electric overhead travelling cranes to show various lifting weights under different scopes.
- Air level. An air level can control support leg to keep the stable of electric overhead travelling cranes by measure chassis’ all-direction levelness of overhead crane.
- Locking support leg rebound device. It can precisely lock the rebound support leg.
- Rotary location device to keep a certain get on place.
- Back-up alarm device. When an electric travelling bridge crane reversing, this equipment can make alarm warn by voice and light.
- Moving parts shield to avoid the risk that the moving parts on electrical bridge travel crane hurt workers.
- Electrical equipment rain covers to protect the electrical kits on electric travelling bridge cranes in case its performance is affected by rain, as well as the forged hook for crane usage.
Several requirements of safety device on overhead crane
1. Two test electrical bridge travel crane requirements on loading limiter
When examine whether the loading limiter is designed according to paint or not, you should notice these two aspects in the following.
First, you should control the error between the count on screen and the real figure at a range of no more than 5%.
Second, once the lifting capacity arrive at the 90% or even 95% of the rated load lifting capacity, related safety device of electric overhead travelling crane will alarm to warn the operators. In the similar way, when the lifting capacity of electric overhead travelling cranes reach the 100% of related load weight, the loading limiter has to cut off the power on the part of hoisting direction, at the same time, the entire warehouse overhead crane equipment should do the downward motion.
Plus: there is no requirement about a jib crane that has to alarm, the working point on this crane is 108% of rated load weight.
2. Six announcements on the test of overhead crane
First, the error comes on the electric overhead travelling crane’s lifting capacity has to in the area of 1% of specified standard.
Second, in the process of test, all operations of electrically operated overhead travelling crane should be done on the basis of “installments and operating instruction”and related safety operation regulations.
Third, the entire test adjust and examine should be done in the state of stop working, at the same time, the operator or electric overhead travelling cranes should cut down the general power on overhead shop crane.
Forth, a long time no less than one month in the test, this 100 ton overhead crane can’t be used, as well as company has to take certain measures to protect this material lifting machine against wind.
Fifth, the operator should consider all the accidents that might happen, and make up of certain effective measures to ensure the safety of all workers.
Sixth, it will be a better way to establish an electrical bridge travel crane test group, all the working in this test unified command to make sure the whole test is organized in an order way.
3. Three tests on the electric overhead travelling crane
First is the strength test on steel structure. Aimed at a new 25 ton overhead crane, the owner has to examine it according to the largest stress zone confirmed by document. And then put forward the analyses result, as well as present sole experiment export, making a detail and precise conclusion.
Second, explosion proof performance test. Under the condition of not any lights, run all parts of this electric travelling indoor overhead cranes on the range of rated load weight, and notice whether there is any spark taken place.
Third, the other test items associated with the electric overhead travelling crane for sale safety and using performance has to fit for the requirements of design and utilization.
