HYDRAULIC LIFTS Hydraulic Home Lift Elevator

Hydraulic lifts use an oil based system that basically moves the lift car up and down using pressure.
A separate room or small box with an oil reservoir (usually very small for home lifts) has a store of hydraulic oil in it. Technical Description :
This is linked to the lift car • System drive: Hydraulic Load
For a very large commercial lift, a large pit is required to house all the oil – but in a home lift this is stored in a
much smaller space and no deep pits are required.

COMPONENTS
All hydraulic lifts function using the same basic components:
• Rod: The rod is connected to the piston and when the lower chamber fills with fluid it raises the piston and rod. PLAN AND
• Piston: The cylinder has a piston with seals that divide the body into two chambers. The piston travels inside
the cylinder body. Oil-immersed hydraulic station

and prevent metal on metal contact.
• Pump: When hydraulic fluid is fed into the inlet port, it will exert force and raise the rod and piston. This can be
accomplished with a hand or foot pump, electric driven pump or air driven pump.

TYPES
• Holed Hydraulic
With this type of elevator, hydraulic cylinders extend into the ground and are placed inside of a drilled hole. The

travel.
• Machine Room-Less (MRL) Hydraulic
In machine room-less elevators, the hydraulic lift mechanisms are located in the hoist way instead of a separate
machine room. This maximizes the available space in a building.

ADVANTAGES CEILING

•
•
Maintenance: they are simple and quick to maintain and service as there are less parts
Weight capacity: hydraulic lifts can usually take a higher weight limit as they are more powerful

• No falling possible: as the system is pressure based, the lift cannot fall to the bottom (this is just in films!)
• Noise: there is very little noise from a hydraulic home lift

SHORTCOMINGS
• Machine room: usually you will need a small box or room to house the pump and oil reservoir – though these

A grid false ceiling is a secondary ceiling system that is suspended from the main structural ceiling. It consists of a grid-like framework made
of metal or other materials, which supports panels or tiles that cover the ceiling surface. ADVANTAGES

APPLICATION INSTALLATION
The installation process of a grid false ceiling involves the following steps:
• Residential
1.Measure and mark the ceiling area where the grid false ceiling will be installed.
• Commercial
2.Install the main runners or perimeter channels along the edges of the ceiling.
• Industrial
3.Install the cross tees or intermediate channels perpendicular to the main runners, forming a grid pattern.
4.Place the ceiling tiles or panels within the grid framework, ensuring a snug fit.
MAINTAINENCE 5.Secure the tiles or panels to the grid using clips or adhesive, depending on the type of false ceiling.
• Check for Water Damage
•
•
Inspect for cracks and damage
Avoid hanging heavy objects
DESIGN CONSIDERATION
The construction of a modular false ceiling involves several steps. While the specific process may vary depending on the type

of material used and the design requirements, here is a general guide for constructing a modular false ceiling:
• Keep it clean
1.Planning and Design:
• Determine the purpose of the false ceiling, whether it's for aesthetic reasons, concealing utilities, or improving acoustics.
• Plan the layout of the ceiling, considering lighting fixtures, ventilation, and any other features.
TYPES • Choose the appropriate material and design based on the requirements and aesthetics of the space.
2.Site Inspection and Measurement:

4.Grid Installation:
• They consist of long metal strips, called "mains," which are interconnected with shorter metal pieces known as and functional.
• Install the metal grid system that will support the modular tiles or panels. This grid is usually composed of main runners

and cross tees.
• Ensure that the grid is level and properly aligned with the room dimensions.
5.Suspension of the Grid:
• Hang the grid system from the existing ceiling or structural supports using suspension wires.
• Adjust the height of the grid to achieve the desired ceiling height.
6.Installation of Ceiling Tiles or Panels:
• Place the modular ceiling tiles or panels into the grid system. These may be dropped into the grid or secured with clips,
depending on the design and material.
• Follow the manufacturer's guidelines for installation, ensuring a snug fit and proper alignment.
7.Cutting and Customization:
• Cut tiles or panels as needed to fit around lighting fixtures, vents, or other obstructions.
• Customize the design by adding different shapes or patterns, if desired.
8.Finishing Touches:
• Fill any gaps or joints between tiles with appropriate filler materials for a seamless appearance.
• Paint or finish the ceiling as per the design requirements.
9.Integration of Lighting Fixtures:
• Install recessed lighting fixtures or other ceiling-mounted fixtures as per the design plan.
• Ensure that the electrical components are properly integrated and concealed within the false ceiling.
10.Final Inspection and Cleaning:
• Inspect the completed false ceiling for any defects or issues.
MATERIAL • Clean the surface of the ceiling tiles and remove any construction debris.
