Application

Gearboxes in cranes and hoists are crucial for transmitting power, controlling speed, and achieving precise load handling. Main applications include:

Bridge Cranes

Driving the trolley along the main beam of the bridge.

Used for lifting and positioning heavy loads in industrial workshops or warehouses.

Tower Cranes

Controlling the hoisting mechanism for vertical lifting.

Enabling slewing and traveling for the placement of construction materials.

Wire Rope Hoists

Providing torque conversion through drum rotation for lifting/lowering loads.

Ensuring smooth operation in manufacturing, logistics, or assembly lines.

Gantry Cranes

Driving the hoisting mechanism for container handling in ports.

Supporting precise load positioning in shipyards or storage yards.

Jib Cranes

Assisting in rotational and lifting movements for localized material handling.

Product processing flow

Box processing process
 

Mechanical modeling of metal mold → casting on production line → artificial aging treatment → shot peening treatment → machining center processing → CMM detection

Gear processing process

Forging → normalizing → rough turning → fine turning → gear hobbing → chamfering of tooth end → carburizing and quenching (HRC58-62) → shot blasting → grinding of the end face and inner hole → gear grinding → accuracy testing (tooth shape, tooth orientation, tooth pitch, etc., level 6) → wire cutting keyway → magnetic particle flaw detection → ultrasonic cleaning and rust prevention.

Process flow of gear shaft processing

Forging → normalizing → rough turning (including center hole drilling) → finish turning → gear hobbing → keyway milling → carburizing and quenching (HRC58-62) → shot blasting → grinding center hole → excircle grinding → gear grinding → testing (tooth shape, tooth pitch, etc., level 6) → magnetic particle inspection → ultrasonic cleaning and rust prevention.

How to select reducer

To determine the model of a reducer, the following parameters need to be determined:

1. Determine the running speed of the machine, and calculate the reduction ratio of the reducer according to this speed (reduction ratio=input shaft speed/output shaft speed=motor speed/mechanical required speed);
2. Calculate the load torque, select the output of the reducer according to this torque (refer to the "Output Torque Table" provided by the reducer manufacturer), and determine the reducer model;
3. Determine the additional functions of the reducer, such as power off braking, power on braking, frequency conversion, shrink frame, housing material, etc. Some additional functions can only be provided by specific factories.
