The weight capacity of a patient sling can vary depending on the specific model and manufacturer. However, here are some common weight capacities that you might encounter: 

1. Standard: Standard patient slings typically have a weight capacity of around 250-300 lbs (113-136 kg). These slings are designed for patients who have relatively low to moderate weight and may require assistance with transfers. 

1. Bariatric: Bariatric patient slings are designed for patients who are heavier and may require additional support and stability during transfers. These slings can have weight capacities of up to 600 lbs (272 kg) or more. 

1. Pediatric: Pediatric patient slings are designed for children and typically have weight capacities of up to 100-150 lbs (45-68 kg). 

It is important to choose a patient sling with an appropriate weight capacity for the patient, to ensure that it is safe and effective to use. It is also important to ensure that the patient sling is installed and used correctly, according to the manufacturer’s instructions, to prevent accidents and injuries.
