The implementation of certain types of work in construction is impossible without a lifting mechanism. One of the most popular models is the Pioneer crane.
Mechanism features
The Pioneer crane is a simple construction that is easy to disassemble. It does not take much time. Due to its small size, the mechanism has high mobility. This makes it easy to transport to the place of use. The unit is installed on the ground, roof and other building floors, in pits and so on.
The design can be made in several versions. For example, an arrow can be collapsible or solid. According to the maximum load that the crane can lift, there are three types: 0.5, 0.75 and 1 ton. In addition, the mechanism can be stationary or mobile (mounted on wheels).
Appointment
The Pioneer crane is used mainly in the construction industry. With it, you can lift loads on the roof and other planes. As the goods may be building materials, tools, installation structures and so on. Thanks to this mechanism, it will be much easier to raise roofing materials, roofing material, insulation on the roof.
The mechanism can be used for loading (unloading) machines, materials, structures. Its operation is possible in a wide range of temperature indicators (from -40 to +40 degrees).
In addition to construction, the Pioneer crane can be used in other industries. For example, it is convenient to work with him in warehouses, in trading enterprises, and so on.
Pioneer crane: technical specifications
As mentioned above, the device may have different load capacities (from 0.5 to 1 ton). All other characteristics will depend on this indicator.
The design allows lifting loads to a height of 4.5 to 6.2 meters. This show is characteristic when the boom is extended to 250 centimeters. The maximum height to which loads can be raised is fifty meters (if you count from the base of the ceiling).
The platform is able to rotate completely around its axis. The rotary mechanism itself can be manual or electric. The lifting of the cargo occurs at a speed of 8.4 to 16.8 meters per second.
For an electric drive that drives the entire system in motion, power is characteristic in the range of values from 4000 to 4750 watts. It works from a network with a voltage of 380 volts.
The lift is small in size. Its length is 2.45-2.85 meters. Width is between 1.77-2.18 meters. Height - from 1.325 to 1.6 meters. The design weighs about 1345-1820 kilograms. In more detail, the main dimensions of the structure (and its individual elements) can be seen in the photograph posted a little higher.
The boom thickness does not exceed 10.2-13.3 centimeters. The rope has a thickness of 0.69-0.78 centimeters.
Device and principle of operation
The design of the mechanism is quite simple. The crane consists of two frames: the main and rotary. A cargo rope, safety straps are attached to them. They are fixed on the arrow, which has the ability to rotate. The arrow can be collapsible or solid. At the end of the boom, a final stop mechanism is installed. A trip switch is installed on the mechanism responsible for lifting the load. The system comes into operation through the use of an electric drive. To keep the mechanism steady, a counterweight is fixed to the frame.
The transported load is secured to the crane hook. In some cases, you can use a special cradle (platform). The load is lifted using a winch, which is driven by an electric drive. To control the process there is a remote control with buttons.
As you can see, the design is very simple and straightforward. This allows you to make a Pioneer crane with your own hands.
