Last month this crane collapsed about 2,000 miles away from Moscow in Russia. This rail mounted tower crane got caught up in some serious winds causing it to gain speed moving down the tracks and collapsing into a nine floor appartment block. Luckily nobody was injured however eight cars were smashed up in the process! This is a lesson to everyone in the lifting industry. Always take the necessary safety precautions (this includes checking the weather!) and risk assessment is vital.
Only in Russia would they continue to operate the other cranes after this had happend! (lol) It is suspected that the crane was not installed correctly- disastrous!

Jib Cranes can become slightly confusing when it comes to making your first purchase as factory management it is your responsibility to ensure everything goes to plan, so reading this article will help you get to grips with Swing Jibs and ensure you pick the right one!
Firstly there is the type of Jib Crane, will you be floor mounting or wall mounting?

Types of Jib Cranes
Free Standing- When specifying a free standing jib crane the jib arm is supported by a floor mounted support, this is secured by chemical anchors that are fitted to the ground and base plate. These can be over-braced or Under-braced, if headroom issues are bound to occur (meaning you do not have enough room above the jib arm to fit the crane) under-braced ensures that the total height of the crane is no taller than the required hook path (height of lift).
Wall Mounted- The name is self explanatory, easily mounted to a wall using fixing stirrups or chemical resin anchors, giving more room on the floor of the production line. Additional height of lift can be achieved at a better cost without the need for tall columns for mounting.
Jib Cranes can have up to 360 degrees of manual or electric slew in order to efficiently and effectively reach material and lift up to 10 Tonnes. For more information and competitive quotations on Donati Swing Jib Cranes please visit Crane Handling.
No company likes to have low productivity rates but sometimes this cannot be helped, for example if you have one overhead crane operating and more than one machine to load at a time such as a group of CNC machines. Each operator has to wait his turn to use the overhead crane to load his machine. This can be easily combatted with the addition of jib cranes. Each machine can have its own dedicated jib crane for a lot less than the cost of one overhead crane. This enables all CNC machines to be loaded at the same time increasing productivity straight away. Another advantage is value for money, more products being manufactured in less time means your employees become worth more to you making your company more successful.
Jib cranes are a lightweight alternative to heavy duty electric overhead travelling cranes. Easily installed and easy to maintain, if one jib breaks down it only leaves one machine and worker out of production, the rest are free to continue. If your one overhead cranes breaks down it can leave your whole team out of production costing you time and money. You then become dependant on a crane service company to perform the repair, this may take time and unforeseen issues such as ordering and waiting for spare parts to arrive can occur thus costing you more time and money. Jib cranes counter act this (unless they all fail at once but this is pretty much unheard of).

Considerations to take into account when looking to purchase a jib crane are the following:
- Capacity- maximum weight to lift, your crane and hoist will be rated to this.
- Height of Lift- the distance between the load to be lifted and the underside of the jib arm.
- Headroom- is there lighting/trussing above causing obstruction to an over-braced jib crane? If so the use of an under-braces solution should be suggested.
- Floor/Wall conditions- if you are floor or wall mounting the jib you need to ensure the floor/wall is structurally sound by acquiring the services of a structural engineer.
- Electricity Supply- if you require an electric slew or hoist you will require a local three phase power supply.
There are many factors to consider when looking for the suitable jib crane, all of which can be supplied and installed by jib crane experts Crane Handling.
