Yes. In Brazil, the Consolidation of Labor Laws (CLT) regulates occupational safety and health standards. For the use of the inclinometer, the applicable regulations are:
NR18
18.14.24.11 The crane must mandatorily have the following safety items: (Amended by Ordinance SIT No. 114, January 17, 2005).
l) device installed on pulleys to prevent the accidental escape of the steel cable;
18.14.24.9. The use of the crane to drag parts, lift inclined or diagonal loads, or potentially anchored loads like the formwork of pre-cast elements is prohibited. (Amended by Ordinance SIT No. 114, January 17, 2005).
NR11
11.1 Safety standards for the operation of elevators, cranes, industrial conveyors, and transport machinery.
11.1.3.1 Special attention should be given to steel cables, ropes, chains, pulleys, and hooks, which must be inspected regularly, with defective parts replaced.

For this type of application, there is no fixed rule. It is necessary to send photos and/or drawings of the chain hoist from various angles so that we can suggest the ideal location.
It is important to note that there is a wide variety of chain hoists on the market, making it impossible to define a standard location.

Yes, on Suspended Scaffolds, Platforms, or any other type of application where inclination could pose risks of accidents to operations or equipment damage.
It can also be installed on the chassis of equipment that moves loads on wheels, such as forklifts, cranes, etc.

Most manufacturers recommend programming a limit angle (φ) that results in a maximum load displacement between 3~3.5% of the crane height in case of swinging.
To calculate this angle, simply use one of the formulas to calculate the area of a right triangle => arctg φ = co/ca
Of the three unknowns in this formula, two are known:
• ca (adjacent side) = crane height
• co (opposite side) = maximum load displacement during swinging = 3.5% of the height.
Thus, it is possible to calculate the angle φ, for example:
Calculation for a crane with a height of 20 meters:
• ca = 20 meters
• co = 3.5% of 20 meters = 0.7 meters
arctg φ = co/ca
arctg φ = 0.7/20
arctg φ = 0.035
Φ = 2.0° => angle to be programmed as the maximum limit.

The system is supplied in two parts: 360º sensor + control electronics.
The 360º sensor must be installed on one of the fixed branches of the crane or on one of the two branches of the compensating pulley.
The control electronics must be installed on the DIN rail of an existing electrical panel on the trolley.
