The presence of a crane is necessary for heavy vertical, horizontal or work at height. In order for this to be done in the best way, a gearbox motor should be used for the crane. In high power cranes, a stronger crane gearbox should be used. Often, parallel shaft gearboxes are used in cranes.
The operation of crane gearboxes is based on reducing speed and increasing torque. The shape of the gears in the production of crane gearboxes is different, and this issue leads to the classification of crane gearboxes into cylindrical, conical and cylindrical-conical categories.
What are the characteristics of a crane gearbox?
Crane gearbox must be made according to international technical standards. In terms of occupied space, it should save space and, in addition, it should have little vibration and noise. Crane gearbox manufacturing companies provide this type of gearbox with high performance and efficiency of about 95 percentage or more, bring to the production stage. In addition, it should be noted that the construction of the crane gearbox should be such that it has a high overload capacity. Other features of the crane gearbox include high durability and security, high power, low energy consumption, and the selection of steel materials. With quality, the resistance created in the gear surfaces by heat treatment and precise machining of the gears is mentioned. All the gears used in the gearbox must be made of low carbon alloy steel and quenched. The use of CNC grinding technology in the production of crane gearbox gears ensures durability, high precision and proper contact between the gears.
Use coil and solar gearbox in crane
One of the types of gearboxes used in cranes is the helical gearbox. Aluminum is used to make the shell of helical gearboxes. The use of aluminum causes the high resistance of the gearbox against vibrations, and as a result, the erosion of the gears is delayed. Maintenance and maintenance of helical gearboxes is very easy and this feature makes it widely used in cranes. Another advantage of the helical gearbox is the soft start of this type of gearbox, which makes the generated noise very low. In addition, the output torque in the helical gearbox has a very high efficiency.
Of course, the use of a helical gearbox also has disadvantages. For example, this gearbox cannot be used in a crane at very high speeds (above 1500 rpm). Also, the helical gearbox has high efficiency, but this efficiency is relatively low compared to other gearboxes (solar gearbox). For this reason, to create high efficiency in the crane, it is more common to use a solar gearbox; Because these types of gearboxes have high efficiency (up to 95%).
In addition to high efficiency, the solar gearbox also saves energy and produces little noise. In addition, this type of gearbox is able to withstand high axial forces.
