Hydraulic Lifts Loading Platforms

Loading platform

The basis of the design of Hydraulic Lifts and loading platforms is the lifting mechanism based on the hydraulic cylinder. Which acts on the load-carrying body directly, through a cable or chain multiplier; also through a lever system that provides compact design and an increase in the lifting height of the loading platform.

Hydraulic Lifts

The movement of the rod or plunger of the hydraulic cylinder to lift is provided by pressure of flow of the working fluid. Which comes from the hydraulic unit.

Lowering the Hydraulic Lifts and loading platforms occurs under the action of gravity. Which acting on the rod or plunger of the hydraulic cylinder. Drains the working fluid into the tank through a special controllable valve device. The latter provides regulation of the flow of working fluid entering the hydraulic cylinder. When lifting and also draining it into the tank when lowering the load. Guaranteeing the required steady-state speed. An acceptable level of acceleration and the necessary stopping accuracy at the loading dock.

The movement of the elevator car is controlled by a control station interacting with the hydraulic system. In addition, sensors for monitoring the position of the car. On floor floors and also in the cabin, the corresponding call buttons and the order apparatus are installed.

Hydraulic loading platform

The hydraulic unit and the control station can be located 5 to 10 meters away from the elevator shaft in a special, enclosed space of small sizes. In this regard, the hydraulic elevator does not have a special machine room characteristic of elevators with electric drives.

Cabins and loading platforms of hydraulic elevators are equipped with lockable doors with manual or automatic drive, with locks and safety interlocks.

On hydraulic lifts, catchers are install and which are switch on by a speed limiter or by a special electromagnetic device that is triggered when the cab is lower excessively.
Along with the mechanical system of catchers in hydraulic elevators, special safety devices are used. Which are an integral part of hydraulic equipment.

Hydraulic Lifts Features

A distinctive feature of the passenger hydraulic elevator is the lateral arrangement of the hydraulic cylinder with a 4-fold multiplier, the ropes of which cover the cab from below. To avoid jamming in the plunger pair of the hydraulic cylinder, the plunger head, together with the moving blocks of the multiplier, moves along special vertical guides. The upper limit level of the cab position is control by a limit switch, which reacts to a change in the tension force of the auxiliary cable with the load.

The cab of this version of the elevator design does not have specific features and is completely analogous to the construction of the squeeze type electric elevator. It moves along vertical guides mounted on brackets mounted on the side walls of the shaft.

hydraulic system

A hard stop is install under the cab in the pit of the shaft. Also Interacting with a shock absorbed on the supporting part of the cab frame. The control station (controller), together with an input device and a hydraulic unit, is located in a locked room of limited dimensions on the side of the shaft. The hydraulic cylinder and hydraulic unit are connect by a pressure pipe.

Loading platforms

The cargo hydraulic platform has a simpler design and the basis of which is one or more hydraulic cylinders acting on the load-bearing base plate through the lever system. In addition, the use of a lever system ensures compact design in the initial position and a sufficiently large height of lifting of the load with a small working movement of the hydraulic cylinder rod.

Hydraulic Lifts and loading platforms Installation

  • Depending on the type of mine from here and the method of mounting the guides and In addition, the elevators are divide with the installation
  • deaf mine (brick, reinforced concrete, block, etc.)
  • metal frame mine
  • combination mine

Goods Loading Platform

The machine room of the elevator can be perform:

  • with the upper engine room (above the shaft)
  • also with the lower engine room (under the shaft or to the side of it)
  • without a machine room
  • Elevators without a machine room

Recently, the revolutionary concepts of passenger elevators have determined the location of the winch. In addition, speed limiter directly in the elevator shaft. There is no longer a need for a machine room or other suitable room. Hence the name “without a machine room”.

The controller is located outside the shaft on the top floor; the controller cabinet is integrate with the portal of the landing door.

The main advantages of this concept are as follows:

  • lack of machinery space, hence a significant reduction in the cost of construction work
  • high efficiency and as a result low energy consumption also
  • ride comfort due to frequency regulation of speed
  • low noise, as there is no gear
