Rohlja - this is the common name of a hand trolley

What lies behind the word "shit"? What can you think of when, for example, in a warehouse a worker is asked to bring a shovel to load piles of bags on it and transport them to the car? A vague recollection pops up in my memory that this is usually called the unlucky person. But it turns out that the shovel is the same as the rock or crumble, and designates a manual hydraulic trolley. Where did this name come from and how appropriate is its use in communication?

Definition of concept

If you find out the meaning of this word in dictionaries, then in the results there are two main versions of its use. The first is associated with application in a negative meaning, with respect to a person who is not very energetic, and also quick decision and action. In the broader sense of the word, rolyh is a weakling, a nerdy, and a nonsense, and so on, in the context of determining the personal qualities of a person who has shown himself off from a disadvantageous side.

In a different sense, as a slang term, it is used to refer to the type of manual trolley with a hydraulic lifting mechanism. It is believed that vernacular came into use after the appearance of forklifts in the USSR.

One of the first in the 60 years of the XX century appeared models from the firm Rocla. These convenient and reliable devices for moving loads on pallets have become indispensable in warehouses. Later, others appeared, but the name of this Finnish firm was firmly entrenched and entrenched. Since then, for many people , rokla, rohlja or rohlja is any manual hydraulic cart without a binding to the manufacturer.

Design

What is this device, which has become a reliable assistant of employees in warehouses and sites for receiving and delivering goods? Rokhlya is a wheeled platform, structurally made in the form of two guide beams (fork type), freely passing into the lumens of a standard pallet. Any cargo can be placed on it.

Rokhlyu pounded under the pallet (pallet) and the handle pumped liquid in the hydraulic jack. That by means of levers and levers raises the forklift platform, tearing the load from the ground to a height sufficient to transport it to the required distance. After that, pressing the hook, the pressure is squeezed out, the jack lowers the trolley and the pallet in the selected place. The trolley freed from the load freely leaves.

The front wheels turn and the rear wheels are permanently fixed. The handle is used to inject pressure, control the trolley and apply force when moving.

Features

In standard models , you usually need to do 10-12 movements with the handle so that the pressure in the jack reaches the desired value. There are options for a small load mass with accelerated lift. They inject the necessary pressure in 4-6 movements. Steering angle (180-200 degrees).

The trolley is smoothly moving along a flat surface. For floors with a good coating, it is advisable to use solid polyurethane wheels or with a rubber coating. If the surface is uneven, the best option would be hard drives made of durable plastic. There are models with one roller on each of the guides. By the way, the variants of tandem cars (two pairs of wheels on the "forks") are easier to move from the place.

Selection

Rohlja hand can have different carrying capacity, differ in the size of the platform, the lifting mechanism, the type and material of the wheels, and also be equipped with additional equipment. Usually they are divided into three classes by weight of the transported cargo (from 500 kg to 3 tons). By the length of the "forks" they can be standard, long (you can take just two pallets) and shortened (for work in confined spaces).

For movement in an aggressive environment, models with an anti-corrosion coating and a special material of wheel sets are used. For the movement of goods on unsuitable platforms, the diameter of the wheel disks is increased - their variants are applied on the pneumatic travel. There are models with a special shear lever mechanism. This design allows you to lift the load to a large height with the ability to install pallets immediately on the shelves of the shelves.

The distribution of the scales with electronic scales has become widespread, which makes it possible to save time and labor costs for additional overloading for weighing. Individual firms produce trolleys with a brake system and an electric drive for easy movement over long distances. For companies using different types of pallets, it is advisable to use molds with variable dimensions of "forks".

Rohlja own hands

Use homemade trolleys to move cargo is inexpedient. Devices must meet safety requirements and withstand planned loads. The hydraulic unit is manufactured without the use of turning and milling equipment is unrealistic. Welding work must be done exactly according to the drawings, so that the working surfaces, the angles of the rods, the axes of the levers and the wheel sets remain.

If there is no possibility to buy a new shoe, there will always be offers for the sale of used equipment. For popular models, you can find repair kits for the hydrosystem, spare wheel pairs. You can change them yourself. Rokhlya, if it was operated under normal conditions, after such maintenance is able to work for a long time and save time and effort during loading and unloading operations in warehouses and trading floors.
