Working Principle of Hydraulic lift (Direct acting and Suspended type)

HYDRAULIC LIFT

Introduction: The hydraulic lift is a device used to lift or bring down passengers and loads from one floor to another in multi-storeyed buildings.

CLASSIFICATION OF HYDRAULIC LIFT

Direct Acting Hydraulic Lift

CONSTRUCTION DETAILS: Components of direct acting hydraulic lift:

  • Fixed cylinder: It is fixed with the wall of the floor, where the sliding ram reciprocate when we apply the pressure.
  • Cage: It is fitted on the top of the sliding ram where the load is placed (i.e. lifted load).
  • Sliding ram: It is fitted in the fixed cylinder which is reciprocate (upward or downward direction) when we applied the pressure (i.e. reaches the floor wise.)

WORKING OF DIRECT ACTING HYDRAULIC LIFT:

When fluid under pressure is forced into the cylinder, the ram gets a push upward. The platform carries loads or passengers and moves between the guides. At required height, it can be made to stay in level with each floor so that the good or passengers can be transferred.

In direct acting hydraulic lift, stroke of the ram is equal to the lift of the cage.

SUSPENDED HYDRAULIC LIFT

CONSTRUCTION DETAILS:

Cage: It is fitted on the top of the sliding ram where the load is placed (i.e. lifted load).

Wire rope: It connects the cage to pulley.

Sliding ram: It is fitted in the fixed cylinder which is reciprocate (upward or downward direction) when we applied the pressure (i.e. reaches the floor wise)

Pulleys: pulleys are connected to the sliding ram and fixed cylinder; where one pulley is fixed and other pulley is movable.

Hydraulic jigger: It consists of a moving ram which slides inside a fixed hydraulic cylinder.

Fixed cylinder-: It is fixed with the wall of the floor, where the sliding ram reciprocate when we apply the pressure.

WORKING OF SUSPENDED HYDRAULIC LIFT

When fluid under pressure is forced into the cylinder, the ram gets reciprocate to the movable pulleys. With the help of arrangement of hydraulic jigger; pulley can rotates; with the help of wire rope the cage is maintain there pressure force with there floor. At required height, it can be made to stay in level with each floor so that the good or passengers can be transferred.

Working period of the lift is ratio of the height of lift to the velocity of lift.

Idle period of lift is the difference of the total time for one operation and the working period of the lift.

    I am a senior citizen and interested in having a domestic lift for my residence on first floor. Would you please send me the literature with your suggestion of lift and how much it would cost to me mentioning terms and conditions.
    Thanks and regards
