Hospital Stretcher Lift / Elevator

                                             Mostly this type of lift has specific kind of access control,This type of elevator is usually hydraulic or traction based depending on the location of the machine room. They are specifically manufactured to be low-noise bed elevators that smoothly transport patients, doctors, nurses and hospital staff between floors, allowing them the utmost in comfort. Because hospital bed elevators are only used for transporting patients and hospital staff they arrived at their location quite quickly, eliminating lengthy waits. Many of these bed elevators are key operated so as to prohibit use by the general public. They usually are smaller than bed elevators. 

Hospital Bed Elevators

                 

                           Hospital bed elevators generally transport patients who are not well enough to sit up even in a wheelchair. One of the features of bed elevators should be its ability to transport the patient has smoothly as possible with minimal amount of bumping and jostling. Many contemporary bed elevators are manufactured to consume extremely low amounts of power and to be durable with a number of safety features built-in. Hospital bed elevators generally draw very little power so that should there be a power outage they are still operational off the hospital's backup power supply. Most often there will be a rear and a front entry to the elevator cabin. 

According to building type - Elevator classification

Elevators will be classified according to building type to 6 main types as follows: 

1. Hospital Elevators.   READ MORE >>
2. Commercial Elevators.    
3. Residential /Domestic Elevators.   READ MORE >>
4. Parking buildings Elevators
5. Agricultural Elevators.
6. Industrial Elevators.

Pneumatic Elevators

                 Pneumatic elevators are raised and lowered by controlling air pressure in a chamber in which the elevator sits. By simple principles of physics; the difference in air pressure above and beneath the vacuum elevator cab literally transports cab by air. It is the vacuum pumps or turbines that pull cab up to the next Floor and the slow release of air pressure that floats cab down. They are especially ideal for existing homes due to their compact design because excavating a pit and hoist way are not required. 

Climbing elevator

Climbing Elevator

                      Climbing elevator   hold their own power device on them, mostly electric or combustion engine. Climbing elevators are often used in work and construction areas.

Machine-Room-Less Elevators

Machine room less elevator

                        Machine-Room-Less Elevators are typically traction elevators that do not have a dedicated machine room above the elevator shaft. The machine sits in the override space and the controls sit above the ceiling adjacent to the elevator shaft. Machine-room-less elevators are becoming more common; however, many maintenance departments do not like them due to the hassle of working on a ladder as opposed to within a room. They are becoming common because this saves productive space in the buildings.

Gearless Traction Elevators

Gearless Traction Elevators

             

                   Gearless Traction Elevators have the wheel attached directly to the motor. Gear-less traction elevators are capable of speeds up to 2000 feet per minute. They use synchronous motors with permanent magnets. These elevators will have more controlled comfort ride. They will be smooth and efficient and produce less sound.  

Geared Traction Elevators

             Geared Traction Elevators have a gearbox that is attached to the motor, which drives the wheel that moves the ropes. This is useful to use low KW motor and reduce cost. Geared traction elevators are capable of travel speeds up to 500 feet per minute. geared machines are less efficient compared to the gear-less one. 

Traction Elevators -types of elevators(lifts)

Traction  ELEVATOR

                        Traction elevators are lifted by ropes, which pass over a sheave attached to an electric motor above the elevator shaft. They are used for mid and high-rise applications and have much higher travel speeds than hydraulic elevators. A counter weight makes the elevators more efficient. Traction elevators have 3 main types as follows

3. Machine-Room-Less Elevators  READ MORE >>

Roped Hydraulic Elevators

          Roped hydraulic elevator is driven by the same piston but the piston here is connected to elevator car using ropes through pulley( sheaves). This can be direct roping or 2:1 roping. This can also use to double the travelling distance of the elevator.

Non-telescoping Hydraulic Elevators - types of elevators(lift)

       In this type the piston plunger will not be telescopic. it have only one Piston. It differ from holed hydraulic elevator as its piston cylinder is not going in to the earth.

Telescopic Hydraulic Elevators - elevator(lift) types

Telescopic hydraulic elevators have  the telescoping pistons  fixed at the base of the pit and do not require a  hole below the pit and has 2 or 3 pieces of telescoping pistons. Telescoping pistons allow up to 50 feet of travel distance. Its load carrying capacity will be a little less than the non-telescopic one.

Holed Hydraulic Elevators

          

            They have a piston cylinder that extends below the floor of the elevator pit, which accepts the retracting piston as the elevator descends. Some configurations have a telescoping piston that collapses and requires a shallower hole below the pit. Max travel distance is approximately 60

feet. 

Hydraulic Elevators

        Hydraulic elevators are driven  by a piston at the bottom of the elevator that pushes the elevator to up levels. They are used for less height applications of 2-8 floors and travel at a maximum speed of 59 meter per minute. The pump room for hydraulic elevators is located at the lowest floor adjacent to the elevator shaft. Hydraulic elevators have many two main types

Types of Elevators / Classification of Elevators

An elevator (or lift in the Commonwealth excluding Canada) is a type of vertical transport equipment that efficiently moves people or goods between floors (levels, decks) of a building, vessel or other structures. Elevators are generally powered by electric motors that either drive traction cables or counterweight systems like a hoist, or pump hydraulic fluid to raise a cylindrical piston like a jack.

There are three types of convoying methods in buildings, Elevators & Escalators & Ramps, and they have different dimensions and uses according to building type & number of users in it.

How Is Job In Elevator Industry

                          Dear friends talking about the Job in Elevator industry, first of all we should talk about "A JOB".

                           A JOB is a task or piece of work, especially one that is paid. 

                  OR 

                                       a paid position of regular employment.

So when some one pays you for your work its not a job. When he gives you work regularly.. then you have a job.

In the case of Elevator Industry you can have a job both inside and outside the company.

1. As a company employee

2. As a subcontractor to company.

The main Area of works are Factory part and Executing part. Executing part will be explained briefly in this post.

In this industry most matters is your experience, than your qualification. But when you start in a company it matters. Till a certain level experience is the main thing, but beyond that stuff turns over.

Main designation you may see in an elevator/ lift company are

1. Manager

2. Sales manager

3. Sales personal & coordinator

4. Field manager

5. Installation head

6. Service head

7. Installation Engineers

8. Service Engineers/ PROJECT MANAGERS

9. Installation coordinator

10. Service Coordinator

11. Installation technicians

12. Service technicians

13. Safety department

14. Quality department

In a multinational or a big company you could have found many chains of job post to withstand the load.

Normally all the posts will not have much more vacancy.

but some posts have more demand

1. Sales person

2. Installation technician

3. Service technician

4. Installation / Service engineers

5. Project managers

6. supervisor ( installation / service )

so i can explain you these five areas as well as i know.

1. Sales Person

            As you obviously know sales person will be selling the product to the potential customers. The main thing all the companies will look consciously is the EXPERIENCE. Most cases the Qualification for these jobs will be MBA. Some places they will look or a Degree. But in good companies the want B tech/M tech/BE. 

           Your knowledge about the current market is very important. If you are a fresher then just go join Local companies for the experience purpose. Most of the good companies seek for 3 - 4 year experienced personals.

           As you know the pressure on a sales person will be huge in an emerging market. But if your company is well established then may be a little free air is there for you. More about the sales category will be published soon.

2. Installation Technician

          The main work , the physical work happening in the job flow is handled by this category. Normally the qualification will be ITI  or any other technical qualification. There are also some short term  courses in this subject. But these are turned out to be useless.

  

           The main thing is experience. You should know the work to get the job. The experience  can be earned by working with subcontractors. To work with good companies you need minimum ITI qualification or very good experience and recommendation. After material delivered to the site when site is ready the installation teams work starts. More about the work will be posted separately and the link  is here

3. Service Technician

           Service technician is for the existing installation. Their work starts by taking over a installation from the installation department. The maintenance team should check and confirm all  the checklist points and take over the site to service departments. The main responsibilities are 

    

         1. Call backs ( Lift break downs or complaints )

         2. Scheduled service (Monthly or in Fixed intervals )

         3. System improvements

         4. Repair

         5. house keeping

Some companies will have a separate team for each of these things. That will be according to the company's business volume. Normally ITI qualification is enough. The qualification is according to the work and stages. For example...  for minor break downs a technician with a sufficient knowledge is enough but in case of a major breakdown,  more skilled man power is needed. More about it is here

4. Installation/ Service Engineers

         These people will be doing the planning and all over looking. They act like a connection chain between who works in the site and who works in the office. so they should have good technical knowledge and the office things. Most of the companies will choose experienced persons with technical degree qualification. Also Diploma qualification can achieve this  position by experience. More of this category is here.

5. Project Managers

         They will be recruited to the company when the sales team brings huge project in to the account. That thing can not be handled by engineers alone. Most of the project managers are Experienced engineers or they would have specialized in project management in their studies. More about them is here

6. Supervisors

         These guys will be looking after some site in all manor. Technical problems, talking to customer, managing the manpower at site. And they will also have to check the quality of the work. 

More about each and every category will be availed soon by posts
