8-10 Meters Double Cab High Lift Platform Truck
Hobbing uses a hobbing machine with two skew spindles, one mounted with a blank workpiece and the other with the hob. The angle between the hob's spindle (axis) and the workpiece's spindle varies, depending on the type of product being produced. For example, if a spur gear is being produced, then the hob is angled equal to the lead angle of the hob; if a helical gear is being produced then the angle must be increased by the same amount as the helix angle of the helical gear. The hobbing features for gears are straight, helical, straight bevel, face, crowned, worm, cylkro and chamfering. The two shafts are rotated at a proportional ratio, which determines the number of teeth on the blank; for example, for a single-threaded hob if the gear ratio is 40:1 the hob rotates 40 times to each turn of the blank, which produces 40 teeth in the blank. If the hob has multiple threads the speed ratio must be multiplied by the number of threads on the hob. The hob is then fed up into the workpiece until the correct tooth depth is obtained. Finally the hob is fed through the workpiece parallel to the blank's axis of rotation.

Aerial work vehicles generally have folding arm, telescopic arm, mixed arm, self-type, scissors  five series.
The structure and working principle of the aerial work vehicle are as follows:
1, the high-altitude work vehicles take force device.
Take the power device from the pump, take the device, the soft axis of the cable composition. Â
2, the high-altitude operation of the car rotation agencies
Rotary mechanism made of the hydraulic motor, planetary gear reducer, slewing ring and other components. Its working principle is: hydraulic motor drive reducer, reducer output shaft on the pinion rotation to promote the rotation support, so that turntable rotation.
3, the high-altitude operation of the central rotary joint
Central rotary joint, installed in the turntable rotation center, to solve the work of the sub-frame relative to the ground static, the upper rotation.
4, the high-altitude operating vehicle hydraulic system
The hydraulic system is supplied by a main pump. The working pressure is 14Mpa and the flow rate is 25L / min. The working pressure is set by the relief valve. Working principle: When the force gear gear, the main pump running, fuel tank through the oil pump output, reach the leg operation valve. After the operation of the legs, the allocation of the handle to the car, then hydraulic oil from the legs to switch to the car on the bus, part of the car can work.

Often, during mass production multiple blanks are stacked using a suitable fixture, then cut in one operation.
For very large gears the blank can be gashed to the rough shape first to make hobbing easier.
