Elevator drive system - passenger elevator can be a roller hydraulic drive elevator, winding elevator, traction elevator, vacuum or pneumatic lift, or heavy chain drive elevator. The type of drive you choose depends on your needs, your budget, family limits, and status codes. All different drive systems need to be maintained at least once a year and have a safety device.
If the motor is in the hoistway, as with the weight of the chain drive without room system, the noise is more. When they move up and down, the counterweight may also produce some noise. The use of hydraulic drive system, the most convenient to use manual drop device. Hydraulic drive elevators and some reel-type elevators require a separate room. The most expensive of the drum-type elevator is the more expensive unit. The vacuum drive or the pneumatic lift is quite noisy, but comes with a shaft or a hoistway that does not require a pit. Not all states are allowed to have no machine room lift and vacuum drive the elevator, so before choosing a certain type of elevator, make sure you check the local code.
Give you a reference, you already know that most small commercial buildings have 2 or 3 stories using a hydraulic lift. Few people can smell the hydraulic oil, so if your sales staff use this reason, you should not buy a hydraulic elevator, we must smell a hydraulic elevator, because it can exclude the hydraulic elevator. Hydraulic elevators take longer and harder to install - especially the most expensive hydraulic lifts, but when installed and adjusted correctly, there should be smoother and quietest ride. The traction drive is also smooth and quiet. If you choose to use a hydraulic household elevator, ask the hydraulic system to carry out the hard tube instead of using the hose. You can choose to use a very short hose in the machine room to make noise directly from the tank. Hydraulic hoses need to be replaced regularly, but hard tubes are not needed. Hydraulic tube should be 80 seamless black tube, not found in the local hardware store. There should be no hydraulic hose in the hoistway. Hydraulic lifts are most likely to be reduced in mechanical failure. If a person uses a wheelchair and can not climb out of the elevator that is stuck between the floors, you may need to choose a hydraulic lift that you can easily reduce to the bottom of the floor by opening the emergency relief valve. Keep in mind that your elevator must be suitable for your elevator, and your needs are not just because it is the only type of sale for a company.
