The main feature of the hoists is that they can hold the lifted load in a desired position without the need for any power and do not need much force to lift this weight. The biggest deficiency of the hoists, also called the differential block, is that the load lifting time is long. The operating times are somewhat longer. The hoist, which is a kind of pulley, consists of two concentric and rotating coils and one movable pulley. They are widely used in small workshops and businesses because they are small in size and easy to maintain.
250 is available in a variety of hoists that can lift weights from 20 to weight. In addition to manual standard handpieces, there are various types of manual chain hoists, chain economic hoists, low ceiling hoists, low ceiling hoists, mechanical hoists, 360 degree rotatable hoists, carriage integrated hoists, electric hoists and industrial type hoists.
As a result, carascals are among the lifting or transmitting machines that take any load from their location and leave it to another place. It is also among the dangerous equipment with its lifting and air retention features. Employees should not be used in any way without ensuring their health and safety.
The hazards caused by carascals are usually caused by faulty and unconscious use. Some hazards are caused by incorrect installation of carascals. But most of the hazards are inadequate control, inspection and maintenance.
Control and Inspection Principles of Hoists
The hoists move on portable legs and can be easily dismantled from their location and mounted on the floor. Simple hoist logic is often used in several-storey businesses or workshops to remove material from the floor to the upper floors. It is also used frequently in construction.
According to the Regulation on Health and Safety in the Use of Work Equipment, the stop systems of all work equipment, including hoists, are a matter of priority over the operating systems. This issue is very important for carascals which can hold a certain weight in the air. In addition, in order not to pose a serious danger to the health and safety of employees, carascals must be fixed and appropriate precautions must be taken against the danger of breakage, rupture or disintegration of their parts.
In accordance with the provisions of the said regulation, unless a period is prescribed for the hoists in other standards, they should be checked and inspected at least once a year by mechanical engineers, machine technicians or high technicians. If the carascals that are not used correctly continue to be used in the enterprises, it is the employer and not the controlling testing and inspection organization.
It has been explained which criteria and standards will be taken as basis for all lifting and transmission equipments used in the workplaces by the Ministry of Labor and Social Security during the control periods and periodic controls. Accordingly, the standards to be taken into consideration during the control of the hoists are:
- Steel wire ropes - Safety - Section 12385: Operation and maintenance information
- TS EN 13157 + A1 Cranes - Safety - Hand-driven lifting equipment
- TS EN 818-6 + A1 Short link chain - For lifting purposes - Safety - Section 6: Chain slings - Technical specification for use and maintenance information to be supplied by the manufacturer
- TS EN 1757-2 Safety in industrial vehicles - Pedestrian controlled vehicles
our organization TÜRCERT Technical Control and Certification Inc.provides control and inspection services for lifting and conveying equipment with a competent manager and employee staff and a strong infrastructure. Within this framework, it provides regular control and inspection services of hoists of all sizes and capacities in a quality, reliable and fast way.
