What does "sc" represent in a construction hoist model?
In the model designation of a construction hoist, "sc" is a shorthand notation that indicates the type of hoist and its load capacity.
S denotes a construction hoist, a type of lifting equipment primarily used in construction for vertical transportation of personnel and materials.
C signifies a rack and pinion drive system, a common mechanism used in construction hoists for their simplicity and reliability.
The numerical part of the model, such as "200/200", refers to the rated load capacity of the hoist cage(s) in kilograms. In this case, both cages have a rated load of 2000kg.
Construction elevators, a subset of construction hoists, are designed to carry people. The incorporation of fall arrest safety devices is a crucial feature that allows for passenger transportation. These elevators typically consist of a car (or cage), a driving mechanism that powers the vertical movement, standard sections that make up the elevator shaft, and an electrical system controlling various functions. The electrical system includes safety devices like travel switches and limit switches to prevent over-travel and ensure safe operation.
