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.
Our 360º Sensor must be installed on one of the fixed branches of the crane or on one of the branches of the compensator pulley.
The sensor will send the signal to the control electronics, which will display the inclination value in degrees (º) and activate three limit relays either instantly or with a delay, both for activation and deactivation, just configure them as needed for each application.
