An OSG rope also Governor rope is part of elevator safety that you will find in the hoistway or overhead space. The second that an elevator car starts falling or even rising too fast, the governor triggers the safety mounted on the car frame and brings the car to a halt. The governor rope runs over the governor sheave and down to the elevator car and is attached to the safety trip mechanism. The governor rope continues all the way down to the pit and runs under a sheave down there and then makes the journey back to the governor. This governor rope arrangement forms a continuous loop while the elevator moves up and down the hoistway. If the car starts going too fast, centrifugal force pushes flyweights outward in the governor against the spring. In simplistic terms it tells the brakes to kick in and stops the car from falling or rising too quickly. As this entire safety system relies on the governor rope, it is very important that it is reliable and in great working condition.
8×19 Class Wire Rope is the world’s most frequently used strand construction for Elevator ropes is the 19-wire Seale strand (1-9-9). The thicker wires of the outer strand layer provide greater wear resistance. Ropes with such strands are mainly used when the rope service life is more strongly impacted by. abrasion than by rope fatigue due to bending.

Elevator lift cable is a vital link between the elevator car and controller. In conventional elevators, all power and signal information is transmitted through the traveling cable. The vast majority, as much as 95%, of wire and cable produced will be installed in a fixed location. The remainder will be used where some motion is required. Many of these cables are easily replaceable, with no serious consequence from any failure. The remaining flexible cables – in motion during service, such as mining cables, oil well boring cables, crane cables and elevator traveling cables – are expected to last. Elevator traveling cable is a specialized multi-conductor cable continually in motion and must last for many years. A generally accepted life span is 20 years – or 3,000,000 flex cycles.
Steel elevator wire ropes are specialized ropes used in elevator systems for vertical transportation. These ropes are specifically designed to provide strength, durability, and reliability to safely lift and lower elevator cars.
The construction of steel elevator wire ropes usually consists of multiple strands of high-strength steel wires twisted together in a helical pattern. The twisting action creates a robust and flexible rope that can handle the weight and movement demands of elevator systems. The number of strands and wires in the rope construction may vary depending on the specific application and required load capacity.
Steel elevator wire ropes undergo rigorous testing and quality control measures to ensure their compliance with strict safety standards and regulations. Factors such as tensile strength, flexibility, resistance to wear and fatigue, and overall performance are carefully evaluated during the manufacturing process.
Regular inspection, maintenance, and replacement of steel elevator wire ropes are crucial to ensure the safe and reliable operation of an elevator system. Any signs of wear, damage, or degradation should be promptly addressed to prevent potential accidents or failures.
A compensating rope, also known as a compensation chain or compensating cable, is a type of rope or cable used in elevator systems. Its purpose is to balance the weight of the elevator car and counterweights to ensure smooth and efficient operation.
In an elevator system, the car is connected to counterweights by ropes or cables. The counterweights help offset the weight of the elevator car and reduce the overall power required to move it. However, the ropes/cables connecting the car to the counterweights can introduce excess tension when the car is at different positions within the shaft.
This is where the compensating rope comes in. It is typically attached to one end of the elevator car and passes over a pulley or sheave at the top of the shaft. The other end of the compensating rope is attached to a counterweight. The compensating rope acts as a flexible linkage between the car and the counterweight, adjusting its length to accommodate changes in the distance between them as the elevator car moves.
By automatically adjusting the length of the compensating rope, the excess tension caused by changes in the car’s position is minimized. This ensures that the overall tension on the main lifting ropes remains relatively constant, allowing for smoother movement and reducing wear and tear on the elevator system.
Compensating ropes are typically made from steel wires or cables to provide the necessary strength and durability. Like other elevator components, they need to be regularly inspected and maintained to ensure safe and reliable operation.
Elevator ropes, also known as hoist ropes or elevator cables, are an essential component of elevator systems. They provide the means to lift and lower the elevator car within the shaft. Elevator ropes are designed to handle the weight of the car, its occupants, and any additional loads with utmost safety and reliability.
Modern elevator ropes are typically made from high-strength steel wires twisted together to form strands. These strands are further twisted around a core to create the final rope structure. The core can be made of either steel or natural fibers, depending on the specific design and requirements of the elevator system.
One important characteristic of elevator ropes is their ability to withstand heavy loads and frequent usage without stretching or breaking. The steel wires used in the construction of elevator ropes have significant tensile strength, ensuring that they can support the weight of the car and counterweights safely.
To ensure optimum performance and safety, elevator ropes undergo regular inspections, maintenance, and replacement as required by regulations and manufacturer guidelines. Over time, due to wear and tear, ropes may need to be replaced to maintain the desired level of safety and functionality.
It’s important to note that elevator ropes are subject to various international standards and regulations to ensure their reliability and safety. Regular inspections, maintenance, and adherence to these standards are essential to guarantee the smooth and safe operation of elevator systems.
The lift rope in an elevator system is the main component responsible for supporting and moving the elevator car. It is sometimes also referred to as the hoist rope or traction cable. The lift rope is essentially a strong, durable, and flexible cable designed to handle the weight of the elevator car, its occupants, and any additional loads safely and reliably.
Modern lift ropes are typically made from high-strength steel wires that are twisted together to form strands. These strands are then twisted around a core to create the final rope structure. The core can be made of either steel or natural fibers, such as sisal or hemp, depending on the specific design and requirements of the elevator system.
The lift rope operates by being wound around a sheave or pulley at the top of the elevator shaft, which is connected to the motor drive system. As the motor rotates the sheave, the lift rope moves, causing the elevator car to ascend or descend.
It’s crucial for lift ropes to have excellent tensile strength and durability, as they undergo significant stress when lifting and lowering the elevator car. They must be able to withstand heavy loads, frequent usage, and the forces associated with starting, stopping, and changing directions.
Regular inspections and maintenance of the lift rope are essential to ensure its reliability and safety. Over time, wear and tear can occur, and the rope may need to be replaced according to manufacturer guidelines and regulatory requirements.
Safety regulations and standards govern the construction, installation, and maintenance of lift ropes to ensure their performance and the overall safety of the elevator system.
Lift and elevator ropes refer to the same component in an elevator system that is responsible for supporting and moving the elevator car. Lift ropes are also commonly known as hoist ropes or traction cables.
As mentioned before, these ropes are usually made from high-strength steel wire strands twisted together to form a strong and flexible cable. The number of strands and wires within each strand can vary depending on the specific design and requirements of the elevator system.
The lift rope runs over a sheave or pulley at the top of the elevator shaft, which is connected to the motor drive system. When the motor rotates the sheave, the lift rope moves, allowing the elevator car to ascend or descend.
Safety is of paramount importance when it comes to lift and elevator ropes. These ropes are designed to handle heavy loads, frequent usage, and the forces associated with starting, stopping, and changing directions. They must be able to withstand these stresses and operate reliably to ensure the safety of passengers.
Regular inspections and maintenance are crucial for lift and elevator ropes. Periodic checks help identify any signs of wear, damage, or degradation that may impact their performance. If any issues are detected, the ropes should be replaced according to manufacturer guidelines and regulatory requirements.
It’s worth noting that lift and elevator ropes require proper lubrication to reduce friction and wear. Lubrication helps ensure smooth operation and extends the lifespan of the rope. However, the choice of lubricant and lubrication schedule may vary based on the type of rope and the specific elevator system.
Overall, lift and elevator ropes play a vital role in the safe and efficient operation of an elevator system. They require regular inspection, maintenance, and replacement as needed to ensure the utmost safety and reliability.
The governor rope in an elevator is a safety device that is part of the elevator’s overspeed governor system. Its primary function is to control the speed of the elevator car and prevent it from exceeding a safe speed limit.
The governor rope is typically made of high-strength steel wire and is connected to the elevator car on one end and to the governor mechanism on the other end. The rope runs through sheaves and pulleys, which are connected to the governor system.
In case the elevator car exceeds the predetermined safe speed limit, the governor mechanism detects this overspeed condition and activates the governor rope. The governor rope then engages with mechanical brakes or clamps to slow down or stop the elevator car, preventing any potential accidents.
The governor rope must be carefully selected and designed to withstand the forces and stresses involved in elevator operation. It is important for elevator manufacturers and maintenance personnel to ensure that the governor rope is regularly inspected, well-maintained, and replaced when necessary to ensure its safe and reliable operation.
