Safety precautions when working with a crane in UAE
Today, skilled labor is one of the most valuable resources in the world. That is why increased attention is paid to the development of safety instructions for working with complex heavy equipment.
If you need to hire a crane in the UAE you can contact Transportation Company by dialing +971-55-141-2400
We list the most common safety requirements when working with lifting equipment:
The crane must be installed on a stationary foundation, while the parameters of this foundation must meet the standards of the design documentation of this equipment.
Persons working on a crane must undergo appropriate training and have certified clearance for lifting work. This requirement also applies to persons performing maintenance and repair of cranes.
It is necessary to observe the temperature and wind conditions established for this model. As a rule, this temperature is from ‒20 to + 40 ° С and the wind speed is less than 6 points.
If you change the object or a long idle time of the crane (over a month), you should configure all the devices responsible for safety, and test with load and idle.
In the case of using the crane at night, the territory on which the work is carried out must be equipped with lighting devices, in addition to those headlights that are on the crane itself.
It is forbidden to store explosive and combustible materials in the operator’s cabin, including lubricating oils, oiled rags, and to heat the cabin with electric furnaces in the cold season.
Reliable grounding of the crane electrical system with a closing device resistance of not more than 4 ohms is required. In addition, it is forbidden to use the crane and even just be near it in stormy weather.
A limited number of persons with the appropriate qualifications and training are allowed to work on a crane; all others are strictly prohibited from entering the operator’s cabin.
There are also additional rules and recommendations governing certain aspects of working on a crane. For example, in the framework of the implementation of high-altitude work, it is necessary to do the following:
The work is carried out jointly by a group of four people: a specialist who carries out general management, a worker to control the energy source, a worker responsible for tightening the bolts, and a specialist in the hydraulic system. No one else is allowed into the work area of the crane.
It is preferable to carry out high-altitude work in the daytime. However, if it is necessary to work at night, it is necessary to provide the maximum possible illumination of the worksite.
The value of wind force during high-altitude work should not exceed four points. Otherwise, stop work, unload the crane, and carefully check the condition of the bolts. In general, during high-altitude work, it is necessary to carefully monitor the condition of the joints and fixtures.
Before starting high-altitude work, it is necessary to check the condition of the electric cable and loosen it so that its length becomes slightly larger than the total lifting height, and the cable reel makes it possible for it to pass freely.
If already in the course of high-altitude work, malfunctions and malfunctions are detected, all work should be curtailed. Only after the complete elimination of all defects can they be resumed. The functioning of broken equipment is not allowed.
Crane control also has its own safety requirements. As noted above, control is carried out only by a professional operator-crane operator, and only he has the right to be to the cabin and is responsible for the operation of the crane during operation. The following general guidelines apply to crane control:
You can only move loads with a known mass, while they must be carefully secured to the cable. Items with custom sizes and configurations should be moved with extreme care.
Lifting a load with an unknown mass is categorically not permissible, as well as overloading a crane, that is, moving a mass exceeding the maximum load of the apparatus. It is strictly forbidden to carry the set loads.
It is necessary to carefully monitor the location of the crane on the job site so that no one is under the boom to prevent the crane or its parts from colliding with other equipment, the structure itself, etc.
