Machine Room Less Elevator
MRLs are a type of traction elevators that do not have a machine room on the top of the hoistway. Instead, the traction hoisting machine is located on the top side wall of the hoistway or on the bottom of the hoistway. The motor is installed with a permanent magnet and works with Variable Voltage Variable Frequency drive. Some hoisting machines use gearless synchronous motors instead of conventional induction motors.
Advantages
- MRLs take up less space in a building since no machine room is required.
- MRLs consume 30% to 80% less power while running than most other types of elevator systems. The power feeders for the MRL are also significantly reduced due to the more efficient design and the counter-balancing provided with traction equipment.
- MRL installations require fewer construction materials and less work time: No well holes to be drilled; no pits to be waterproofed; no requirement for a structural machine- room slab.
- MRLs require significantly less on-site service time than older elevator systems.
- Effective for high load requirements.
- Lowest cost down speed amongst all elevators as gravity is utilized as the motive force.
- No hydraulic oil used – Currently, there are some environmental concerns with oil usage and possible oil seepage or spills, especially in elevators with in-ground jacks.
Hydraulic Elevator
Hydraulic lift is the Lifting Mechanism which is commonly used in modern Buildings, Homes, Hospitals and Industries. These Lifts works on the principle of an electrically powered pump that pushes pressurized hydraulic fluid (Oil), to a jack lifting system. A piston within a cylinder at the base of the elevator pushes the car of an elevator system up and down.
Hydraulic Lifts are usually smooth, comfortable, noiseless and one time investment as compared to traction lifts. This Lift also occupy less space as lift shaft requires about 10 per cent less area than any other type of lift mechanism and low energy consumption as well.
Roped Hydraulic Elevator
In Roped Hydraulic Elevator, both ropes and a piston are using to increase the motion of the elevator. The maximum distance can be travel in this type of hydraulic mechanism is about 50 feet.
Conventional Hydraulic Elevator
These Types of Lifts generally designed with a sheave that extends beneath the floor of the pit. The pit of a Conventional Hydraulic Lift supports a retracting piston. The approximate distance it can travel is 60 feet.
Hole-Less Hydraulic Elevator
It doesn’t require a hole or sheave fixed below the pit. It has telescoping pistons at the base of the pit. There is also a design that has non-telescoping pistons, which can only allow up to 20 feet of travel
Home Elevator
Traction Lifts is essentially a box on steel ropes that are looped around sheaves connected to an electric motor. The sheaves have a counterweight attached at their end to balance the load of the elevator car. Traction on the ropes raises and lowers the elevator.
The main advantage of a traction lift is its higher speed compared with the hydraulic variety. This means the traction system can be used in tall, modern, 21st-century buildings. The ride in a traction elevator is also smoother.
In terms of energy usage, traction lifts are generally more energy efficient. This is due to the differences the way the two types of lifts work.
Geared Traction Elevator
The geared elevator is made up of a motor that has a gearbox attached to it. The main function of the gears is to power the wheel that moves the ropes. This type of elevator can travel up to speeds of up to 500 feet per minute. The maximum distance it can travel is 250 feet.
Gearless Traction Elevator
Gearless elevators don’t have a gear for speed regulation. This explains why they can move as fast as 2,000 feet per minute and can also travel a maximum of 2,000 feet. They are the best option for a very tall building of many storeys.
Hospital Elevator
Force Elevators designs, manufactures, installs, modernizes, and maintains Hospital Elevators, and goods elevators to make it easier to transport patients, medical equipment, food trolleys, etc. Hospital Elevators designed by Force Elevators for hospitals offer all car sizes as well as supports and finishes to ensure the most hygienic conditions for patients and better usability and comfort for visitors, doctors, and other professionals.
Machine Room Elevator
MR elevators need a machine room for the machinery that operates the elevator. The room is above or next to the hoistway hoist-way. It contains the motors, gears, and other mechanical components that power the elevator.
Dazen small machine room elevator technology helps you to increase the efficiency of your engineering and accelerate the speed of project progress. The use of Dazen small machine room passenger elevator can ensure smooth operation of the engineering. Therefore, no effects will be brought to the progress of the engineering due to the installation of the elevator.
Goods Elevator
Force Elevators are used in all kinds of industries. With these elevators, customers have better access, monitor and service key processes in their plants. Force Elevators will improve operational efficiency, give superior Safety performance and reduce maintenance costs in any industrial application.
Developed to withstand the extreme conditions of the world’s most hostile environments, our industrial/goods elevators have proven invaluable in many industries including Oil & Gas, Metals & Steel, Cement and Power industries.
