How are stackers different from reach trucks?
5 differences between a stacker and a reach truck
A forklift is the most popular type of warehouse equipment. With its help, 2/3 of all loading and unloading operations are performed. This category of warehouse equipment includes two variants of special equipment: stackers and reach trucks. The latter have narrower functionality. What is the difference between them? What are the features of the special equipment? Let's talk about everything in order.
Range of stackers
The main purpose of the loader is to stack loads and lift them onto the upper shelving shelves. The equipment is characterized by a compact design, therefore it copes well with its functions in a limited space. Even if the aisles are narrow, stackers can be used. The operation of the equipment is controlled using a long handle. Therefore, during the operation of the equipment, difficulties do not arise.
Depending on the difference in design and control features, stackers are classified into several models:
Mechanical devices. Equipped with a lifting mast, a frame with forks, on which pallets are installed, a chassis on swivel wheels, a hydraulic unit that is manually started. The model is not suitable for frequent use, because mechanical devices are the best choice for warehouses with a small cargo turnover. The technique is capable of lifting pallets to a height of up to three meters, due to which it has found its application in various fields.
Electrohydraulic devices. The design is based on a lifting mast, a frame with forks, stable wheel supports, a hydraulic cylinder, the work of which is activated from a storage battery or an electrical network. The functionality of the model is impressive: the electro-hydraulic device is capable of lifting a load to a height of 6 meters.
Self-propelled machinery with electro-hydraulic drive. This model, in contrast to mechanical and electro-hydraulic devices, has a wider functionality. Self-propelled vehicles can lift loads to a height of 8 meters. She moves through the warehouse at a speed of 8 km per hour. On one battery charge, the equipment can work up to 10 hours. The carrying capacity of the equipment is up to 3,500 kg. This model features quiet operation, inexpensive maintenance, and simple operation.
Special equipment of this type has found application in warehouse conditions, which are characterized by dense placement of racks.
Reach truck design features
This model of special equipment combines the best qualities of a stacker and a forklift. The reach truck is designed to work in a warehouse with a storage height of up to 12 m, in confined spaces - with narrow aisles (width must be at least 1,600 mm).
Structurally, the technique consists of the following elements:
frame made of galvanized steel;
telescopic mast that can be extended;
pitchforks that differ in free or non-free travel;
wheel supports, providing the ability to move the structure on the floor;
operator's booth. It provides for the installation of a panel, with the help of which the operation of the equipment is controlled;
counterweight, providing balance, which improves control over the implementation of the operation
To expand the functionality of the equipment, it is possible to complement it with other devices (for example, telescopic forks or tilt mast).
Attention! The use of a reach truck for work can increase the storage density of goods by one third or more (depending on the height of the room and the type of rack structure).
The main differences between warehouse equipment
Experts recommend choosing forklift trucks taking into account their technical characteristics, which determine the operational properties of the equipment. At the same time, you need to understand how stackers and reach trucks differ:
Construction type. The stacker is equipped with a stationary mast, the reach truck is retractable. In the first case, the movement of loads is provided only in the up-down direction. Rich truck belongs to the category of more technologically advanced equipment, since its design provides for the installation of a retractable forklift.
Maximum lifting height of the forks. In reach trucks, it reaches 12 meters, but stackers are characterized by more "modest" performance. They are capable of lifting the forks to a height of 8 m.
Maximum load capacity. The lifting capacity of the reach truck is up to 2,500 kg, of the stacker - up to 3,500 kg.
Productivity and precision. Richtrak confidently wins this nomination. With the help of this technique, cargo handling is doubled.
Wheelbase type. Reach trucks are equipped with supports with a diameter of about 200-250 mm, stackers - only 80 mm. Large wheels allow the vehicle to easily overcome any obstacles on the way. Due to this feature, reach trucks move without problems on rough floors. At the same time, you need to understand that the wheel bearings experience high loads during the operation of special equipment. If the operating rules are not followed and maintenance is not timely, they fail, paralyzing the performance of warehouse operations. To restore the equipment's performance, it is necessary to quickly replace worn-out components, having previously familiarized yourself with the range of wheels on the website https://www.fregat.com.ua/katalog/
Due to their simple design, stackers are more affordable than reach trucks. The choice of equipment is necessary taking into account the operating conditions and the type of work, starting from the needs of the enterprise and the allocated budget for the purchase of special equipment. The price of a reach truck quickly pays off for its increased productivity and wide functionality.
