Product Description

The crane gearbox, also known as the crane gear reducer or crane gear unit, is a mechanical device that is used in cr anes to control and transmit power between the crane motor and the crane drum or ho ist mechanism. It is an essential component of the crane 's power transmission system. The crane gearbox is typically mounted between the crane motor and the drum or ho ist mechanism. It consists of a series of gears that are arranged in a specific configuration to achieve the desired speed and torque conversion. The gears in the gearbox are designed to mesh and rotate together, transmitting power from the input shaft ( connected to the motor ) to the output shaft ( connected to the drum or ho ist mechanism ).

Product Description

1. B/T8905-1999 standard, medium hard tooth surface reducer.

The three-point structure can be installed horizontally or vertically: QJ type reducers are divided into R (B) type - second stage, S (C) type - third stage, and RS (D) type - second stage installation dimensions, and third stage speed ratio (second stage folding shaft type)

2. The QJ-D type reducer with a base structure is divided into two stages: QJR-D (QJB-D) and QJS-D (QJC-D). The QJRS-D (QJD-D) model has a two-stage installation size and a three-stage speed ratio.

3. The gears and gear shafts are made of high-quality alloy steel and undergo quenching and tempering treatment.

4. The three-point structure box is a welded box, and the base type box is a cast box or welded box.

Product Features

1. Compact structure, small volume, and light weight: Crane gearboxes are designed to be compact and lightweight to reduce the weight and size of the crane system, which can improve the overall efficiency and reduce the cost. 2. High efficiency, low noise, and small vibration: Crane gearboxes are designed to be highly efficient, producing low noise and small vibrations during operation. This can help to ensure a smooth and reliable operation, which is crucial for crane systems. 3. Increased transmission center distance, reduced gearbox height: To meet the requirements of the crane system, crane gearboxes are designed to increase the transmission center distance and reduce the gearbox height, allowing for more flexibility in the operation mechanism. 4. Higher operation reliability and enhanced transmission power: Crane gearboxes are designed to provide high reliability and enhanced transmission power to ensure that the crane system can handle heavy loads and operate safely and efficiently.
