Low-speed ladders, often referred to as elevators with speeds below 1.00 m/s.
The medium speed ladder is often referred to as an elevator with a speed of 1.00 to 2.00 m/s.
High-speed ladders, often referred to as elevators with speeds greater than 2.00 m/s.
Ultra-high speed ladder, elevator with speed exceeding 5.00m/s.
