Warehouse elevators are high-capacity equipment intended for vertical transportation of large-sized luggage to various levels. They significantly increase the productivity of the enterprise, efficiency of work and help to save the company's resources. Cargo lifts are installed in industrial production complexes, commodity-material bases, public and administrative buildings or in modern country houses in addition to passenger elevators. The equipment is indispensable also in workshops and warehouses (for increasing freight turnover), in supermarkets, shopping centers, hospitals, hotels, restaurants, airports, railway stations, etc.
Characteristics of cargo lifts
To achieve maximum efficiency, when selecting elevator equipment, it is necessary to take into account a whole set of parameters. They depend on where, under what conditions and how the hoist will be operated. In addition, the intensity of the proposed work should be predicted taking into account the speed of cargo traffic and the volume of cargo.
Drive unit. Lifting equipment for lifting or lowering large loads can be with a hydraulic or electric drive.
Electric elevators are ideal for work in multi-storey buildings and potentially explosive areas. The electric hoist is the "heart" of the lifting equipment, which "beats" thanks to the power drive. The electric drive can be installed at the bottom, top or side of the shaft, and if necessary even outside the shaft.
The hydraulic lift moves due to the oil pressure in the hydraulic cylinders. It is characterized by greater load capacity and lower noise level during operation. In addition, it is cheaper to operate.
Mine. Most cargo lifts do not require the arrangement of a classical shaft with bearing walls - they are provided with self-supporting or load-bearing metal structures. This is a vertical metal structure of rectangular cross-section, inside of which a stand (cab) moves. From above, the shaft is sheathed, lined or protected with a mesh. Install it, usually on a concrete foundation, made in the form of a pit, a depth of at least 1000 mm. However, some models require installation in a brick or concrete shaft.
Cabin. It is made of strong materials in the form of metal modules, protected by a special hard paint and varnish. In order to increase the service life, the coating is often applied using powder technology. Particular attention in freight elevators is given to the material from which the floor of the cabin is made. For him, solid corrugated sheets of steel are used, capable of withstanding heavy loads.
The elevator doors. They differ in their design in accordance with the specifics of the work. Can be: manually opened, swinging, sliding or automatic constructions with one or two leaflets. Loading - manual or by means of floor transport, can be carried out from one or two sides. The blind hinged or sliding doors of the shaft are installed in such a way as to protect the casual access of people to the working area of the lifting equipment. The automatic control system of locking the doors of the shaft blocks the movement of the cabin if they are open, and also does not allow them to open when the cabin is between floors.
Load-carrying capacity. This is the main characteristic that should be selected depending on the maximum weight of the cargo being transported and the size of the platform on which the elevator is mounted in order to minimize the risk of accidents. Load capacity can vary from 250 kg to 10 tons.
Speed. Virtually does not affect the operation process, and usually does not exceed 0.5 m / s.
Control. It can be external, internal or mixed. Most often, this is an external control, which allows you to transport the goods unaccompanied. The cab is controlled from a fixed pushbutton installed on each floor of a freight elevator stop. On the post there should be an emergency stop button "Stop".
Safety systems - mechanical catchers of a cabin, not allowing its fall in case of cable breakage. Simultaneously with the trap, the system for blocking the hoists operates, disconnecting the motor. The motion control system (or emergency braking system) stops the drive if the cab moves after the first floor has been traversed. And the wire loosening sensor will help to avoid accidents.
Additional functions. At the request of the customer, the elevator equipment can be equipped with additional features. For example: light indicators, intercoms, microprocessor control stations, flaps, doors of various designs or sectional gates, as well as other details that will make the process of transporting goods as fast and productive as possible.
There are also "hiking" variations of freight elevators:
cargo lifts without engine room - elevator equipment for moving loads, accompanied by people;
squeezed elevators - equipped with lifting ropes, which grasp the cabin from the bottom and lift up;
hydraulic scissor lifts (the same lifting table or scissor lift) - equipment without load-bearing structures, which is used as an equalizing platform for reloading operations, for lifting cars in car service centers and for moving large-sized heavy products.
cantilever lifts with hydraulic drive - for lifting loads up to 3000 kg. They differ in that the supporting structure is a self-supporting mast (frame). Elevators of this type are divided into:
single-masted - for cargoes from 250 kg to 1000 kg;
Two-masted - for goods from 500 kg to 3000 kg.
Thus, it is possible to correctly distribute the weight of the goods and improve the performance indicators.
How to choose a warehouse elevator?
If you need to buy a lift for lifting goods, the best option is to entrust the selection process to professionals. Employees of the company «Tries Group» perfectly know the conditions of production processes, as well as the functional purpose and characteristics of suitable models.
The presented brands are characterized by increased strength of load-bearing structures, functionality and safety in operation, therefore they can be used even in potentially explosive areas. And this is very important, since reliability, efficiency and endurance of the lifting equipment depend on the uninterrupted operation of the enterprise, the pace of production processes and the safety of workers. To order a specialist lift truck, the price and quality of which you are satisfied with, it is enough to make a request.
Certified elevator equipment from leading manufacturers, purchased at the company «Tries Group», will help to establish fast, safe and stable delivery of goods, shipment of raw materials or movement of other heavy cargo.
