20 ton overhead crane, a kind of heavy duty crane, is mainly used for lifting and transporting work in steel, metallurgy and building material industry. Ellsen Group, one of best lifting crane suppliers, provides various types of cranes with safety protection devices, especially for heavy duty cranes. Safety protection devices include limiting stopper, crane buffer, anti-collision device, anti-deflection device, overload limiter.
Price of 20t overhead cranes
Many customers want to know the price of 20 ton overhead cranes.But the answer is not obvious. Because the bridge crane price is not stable, especially the steel price is still raising, the crane price changes quickly.
20t crane price is related to spam, lifting height and traveling distance. These are main factors for engineers to calculate the cost. And before estimating the cost, the crane drawing is first. This is a complex process.
Ellsen Group is a professional bridge crane manufacturer and supplier in China. Ellsen cranes have many advantages, such as advanced technology, compact structure, easy operation, simple maintenance, low investment and wide application. Ellsen lifting cranes are hot sale at home and abroad.

Safety protection of limiting stopper on bridge cranes
Limiting stopper is a kind of protection device to limit the travelling area of mechanism. It includes two categories, one is the limiting stopper of rising extreme position and downing extreme position to protect lifting mechanism, and the other is limiting stopper of travelling extreme position to limit the traveling mechanism.
Why crane system need buffers?
Three kinds of buffers are used widely, spring buffer, rubber buffer and hydraulic buffer. Spring buffer is reliable and convenient to maintain. Rubber buffer has simple structure. Hydraulic buffer can absorb large hitting energy and has no rebound effect.
When limiting stopper of travelling extreme position or brake is in trouble, due to the inertia, the crane system moving in the end or the trolley on the main girder, will hit against the stopper set in the position. But crane buffer can absorb the travelling energy of crane system or trolley and reduce impulsion. Buffers should be set between the bridge cranes travelling on the same track, or between the double trolleys on the same girder.
The use of overload limiter on lifting crane
Overload can make harm to the crane system itself and endanger the operator, so the overload limited must be installed on hoisting cranes to ensure the crane safety. Overload limiter includes two types: automatic-stop type and ring-bell type
The function of anti-collision device on cranes
It mainly includes laser type, ultrasonic type, infrared type, electromagnetic type, all use the principle that light or radio wave travels, reflects and the distance can be measured. When two overhead cranes travels to pointed position, the crane mechanism rings alarm bell and gives the stop command at the same time.
How does anti-deflection device protect cranes?
It includes wire-rope type, cam type, chain wheel type and skew indicator and other automatic adjustable devices. When the bridge frame deflects to some degree, it can give signal to the operator and adjust itself automatically. When the crane frame deflects seriously, it can cut the power automatically, stop the travelling mechanism and protect the safety.

Safety tips about 20 ton traveling overhead crane
20 tonne bridge crane is kind of heavy duty crane. For a large and heavy lifting device, the safe operation is very important. For the operator, correct operation can protect the operator away from damage and accident. For the crane itself, safe operation can reduce broken risk and ensure long service term. The followings are about crane safe operation tips.

Why do more customers choose customized overhead cranes? The reasons are as following.
First, customized bridge crane is special. Different working conditions needs different lifting cranes. For explosive environment, explosion-proof overhead crane is suitable, for high temperature, construction bridge crane is good, for casting work, casting bridge crane can accomplish loading and unloading work well. For transporting iron bulks, electromagnetic overhead crane is wonderful.
Second, customized crane can adapt to lifting work better. In this way, crane can increase working efficiency and save much energy and time.
