A chairlift can also be referred to as an elevated passenger ropeway. It is classified as a form of aerial lift that is comprised of a steel cable loop that is strung between the two end terminals. The steel cable loop is usually circulated continuously while the distance between the two end terminals is marked by intermediate towers. Also, the steel cable loop carries multiple chairs. This is worth knowing about Baltimore Chair Lift.
Majority of ski areas use chairlifts as an onhill transport. Chairlifts are also common in amusement parks and tourist attraction sites. Their popularity is also growing in multiple places around the world as a form of urban transport. There is a likelihood of this form of transport being used on a larger scale in the future so that it can make a considerable percentage in the transport network.
The sizes of the carriers vary a lot and so does the capacity. If the carrier is big and has operating efficiency of a high level, it can transport 4000 individuals every hour. The speed of the fastest lifts reaches 12 m/s or 43.2 km/h. Some models come with two or four chairs, which give them more capacity. They can move between 1200 and 2400 passengers every hour respectively.
The rope used in these systems is designed to stretch and contract depending on the amount of tension applied to it. Also, the rope flexes and bends while passing around bullwheels and over sheaves. To protect the rope from corrosion and to allow flexing operation to occur smoothly, lubricants must be applied on it regularly. Regular lubrication also prolongs the life of the rope.
There are two terminals in every lift system with additional support from intermediate towers. Sheaves and bullwheels are used to offer support to the rope above the ground. Sheaves are held in towers while bullwheels are located in the terminal. There are a number of factors considered in designing the number of towers incorporated in the system. They include terrain type, rope strength, and length of rope.
This system usually comprises of one drive terminal for generating the force needed to drive the ropes. The drive terminal also houses the braking systems. There are several braking mechanisms incorporated into the systems for safety purposes. Two major braking systems are the emergency brake and the service brake. The service brake is positioned before the gearbox on the drive shaft.
The emergency brake is meant to be used in emergency situations. Its effect is generated by acting directly on the bullwheel. Another useful braking mechanism is the anti-rollback device, which also acts directly on the bullwheel. This device is meant to prevent the rope from moving in the reverse direction. Runaway reverse operation can be very disastrous if it happens.
Sagging of the rope is caused by wind load and passenger weight. Other sources of sagging include rope length and temperature variation. The rope needs to be tightened regularly to counteract the effect. To achieve this, one uses pneumatic rams, hydraulic rams, or counterweights. Majority of chairlifts have their tension quantified in terms of tons.
