The elevator installation consultant should evaluate the capability of the entire system for you to develop a thorough analysis of the system. The first step in this exercise is to use the information gathered in the study described earlier to create a mathematical model of the elevator system and the demands placed on it. This model will help managers track the effects of any improvements or modifications made to the system later on. Before spending any money on modernization, managers may decide to implement some changes in elevator assignment or usage that can dramatically improve overall service within the building like eliminating elevator stops in a building’s basement or other seldom-visited floor can reduce undue waiting for tenants. Similarly managers may consider relocating a cafeteria or mail room to allow for easier access and fewer elevator tie-ups. Other no-cost changes that can do wonders for improving elevator service includes- arranging for freight to be moved on an assigned passenger elevator during off-peak hours; encouraging tenants to stagger starting, quitting, and lunch hours; reassigning to general duty any cars that had been reserved for specific tenants’ exclusive use; and relocating certain offices or departments so that co-workers need not use the elevators in order to meet with one another.

It is important to note that the modern, solid-state controllers replacing the old motor generators often will require additional power. In addition, microprocessors are heat-sensitive, and so may demand the installation or upgrade of an air-conditioning system in the machine room. These and other factors must be considered when budgeting for a modernization program and considering the merits of various product lines. Car improvements and fixture upgrades will be necessary in almost any modernization for tenant appeal. Many experts also are predicting the widespread adoption of the requirements now in place in most major cities for extra safety fittings in elevator cars. These requirements include smoke detectors and enhanced car-to-centralisation communication capability. At some point, you must consider a complete overhaul of the system. Such a move is recommended for all elevators that are 20 or more years old. However, rapidly changing technology and the retirement of technicians with experience on older systems may make it necessary for all systems to be modernized in the foreseeable future. Elevator installation consultant deals with providing you the required information and details about upgrading your elevator.

You should note that replacement of an elevator leveller is truly the ultimate fix; and usually requires a corresponding upgrade in elevator controllers. In a pinch, a mechanical leveller may be replaced with hoist way switches until a full overhaul is possible. Controller replacement is the most significant modernization step. In most cases, those looking to upgrade a group of three or more elevators will replace the group or dispatching controller with a new microprocessor that can direct the overall operation of each elevator in that group. Be sure to select a microprocessor that is compatible with both the existing individual car controllers and with the ones that will be installed to replace them, so that the entire system can continue to operate throughout the modernization process. Elevator modernization consultant engineer have the ability to evaluate many factors and to make split-second decisions to direct cars to serve landing call traffic extremely efficiently. However, those who decide to install a microprocessor also should contract for continuing maintenance from the manufacturer, as diagnostics and adjustments often are exclusive to that vendor. A second option is to find a supplier who offers generic equipment that can be maintained by any competent company.

Before undertaking any major modernization project, they must ensure that any elevators not being serviced are operating at peak capability. Elevator modernization consultant engineer evaluates the existing elevator system to determine which components, if any, may be retrieved. Firstly you need to take a critical look at the elevator entrances. Doors constructed of modern flush hollow metal can be reused, but panel-type or older glass doors most often will have to be replaced. In many cases, existing frames may be kept and covered, and worn sills can be salvaged by adding a “layon” sill on top of the old one. Next, the engineer should check out the condition of the elevator’s operating mechanism. Pay close attention to the door operator; many openers manufactured in the last 20 years are of good quality and may be overhauled and reused. Similarly the elevator’s tracks, locks, and hangers can be reconditioned. When evaluating the condition of the leveller, you should remember that elevator cars today employ a variety of levelling mechanisms. Levelling systems that employ a sensor that is mounted directly on the car in the hoist way can be reused; while levelling systems that employ a wire or cable that is attached to a separate mechanism located in the machine room are considered obsolete today and so must be replaced.

There is always scope for elevator maintenance program to improve in case of inefficiency in maintenance, no modernization program, no matter how elaborate, will allow the system to perform effectively. At the times when the elevator service is substandard, managers must take help of consulting lift services and take deliberate steps to determine the exact cause of the service shortfall before making any decisions to repair, replace or modernize the system. The first step in equal car performance analysis is to establish that if all elevators in a group are performing equally. In order to do that, managers can use a stopwatch and chart the time it takes each car to perform its various functions. At the initial stage, measure how quickly each car’s doors open and close at each floor. Most passengers agree that an elevator’s doors should open as quickly as possible. However, the speed at which the doors may close is limited by elevator codes that prevent elevator doors from using more than 7 foot-pounds of kinetic energy and 30 pounds of thrust. Generally speaking, a 42-inch-wide, centre-opening, hollow metal door can be expected to close in 2.3 seconds. Lift consulting engineer are aware of this and will inform you the needful measures.

The elevator problems, be it of any form which means a large scale modernization effort or a simple maintenance procedure, in order to solve them the property manager first need to determine the clear definition of the problem. Lift consulting engineer helps in identifying and providing measures to the problem. There occurs a time when you hear complaints of long waits, slow trips between floors and delayed opening and closing of elevator doors. A manager facing this situation should answer few questions before consulting lift consultant. The most important question of all is to find if the existing elevator equipment is capable of handling the elevators needs of the building. Perhaps the system simply is too small to accommodate all of the building’s current traffic, and so needs more than modernization to bring it into line with building demands. You need to also check if the equipment is in proper state or outdated, run down or is unserviceable- that it requires a major overhaul. If so, which components can be upgraded and which are the ones that must be replaced. Look out if the existing maintenance program is adequate to maintain the system’s volume of use.

Elevator modernization consultant engineer knows your requirement and consult installation that is the best. The most highly skilled elevator installers and repairers, called “adjusters,” specialize in fine-tuning all the equipment after installation. Adjusters make sure that an elevator is working according to specifications and is stopping correctly at each floor within a specified time. Once an elevator is operating properly, it must be maintained and serviced regularly to keep it in safe working condition. Elevator installers and repairers generally do preventive maintenance—such as oiling and greasing moving parts, replacing worn parts, testing equipment with meters and gauges, and adjusting equipment for optimal performance. They also troubleshoot and may be called to do emergency repairs. A service crew usually handles major repairs. This may require the use of cutting torches or rigging equipmen. Service crews also do major modernization and alteration work, such as moving and replacing electrical motors, hydraulic pumps, and control panels. Elevator installers and repairers usually specialize in installation, maintenance, or repair work. Maintenance and repair workers generally need greater knowledge of electricity and electronics than do installers, because a large part of maintenance and repair work is troubleshooting. Similarly, adjusters need a thorough knowledge of electricity, electronics, and computers to ensure that newly installed elevators operate properly.

A common problem with elevator installations is the overheating of the drive and control system. In electrical traction elevators, the equipment is typically located in a penthouse above the building’s roof. The penthouse is seldom heated or cooled. With this type of installation, the temperature in the mechanical room is allowed to float with changes in the outside air temperature. As the temperature increases, so does the chance of breakdowns caused by overheating. Attempting to cool the elevator equipment with outdoor air also introduces other causes of frequent breakdowns: dirt and humidity. The best solution to this problem is to install a dedicated cooling system for the elevator equipment room. The system should be designed to keep the temperature and humidity within the recommendations of the elevator manufacturer. All openings to the outside should be sealed to help limit the dust and dirt that can enter the equipment room. One of the most common symptoms of a system in need of overhaul or modernization is increasing service call frequencies. As components wear and age, they more readily go out of adjustment, either shutting down the system or interfering with its operation. It is important to track the frequency and costs of all problems while indulging in escalator consulting services.

Ignoring elevator maintenance leads to series of problems starting with rapid decline in performance, increase in response time, downtime and rapid hike in cost. The service life shortens with rise in complaints. Most important of all, safety will be compromised. During such times, even with the most comprehensive maintenance program, all elevators system will eventually need to be modernized or replaced. Postponing modernization too long will result in the same detrimental effects that result from ignoring maintenance requirements. Elevator modernization consultant engineer takes care of this need. Some elevator problems, such as system downtime and slow operation, are obvious. Others, such as high-energy use and electrical noise generation, are not. Their impact, however, may be felt throughout the entire building. Waiting for long times causes inconvenience for building occupants. Wait times and elevator speed should be checked on a regular basis. Time how long it takes to go from the bottom floor to the top floor. Long wait times and slow performance may be caused by a malfunction as simple as a defective relay, or problems may be caused by the age and overall condition of the elevator. While repairs can improve performance in some cases, elevators that use old mechanical relay control systems may simply need a new control system.
