Earth Moving Machinery Spare Parts 7D9999 Cutting Edge Wheel Loader

The specifications of different types of edge teeth in construction machinery vary

The specification differences of the edge teeth of construction machinery are mainly reflected in the tooth profile structure, size parameters and applicable scenarios. The specific classification is as follows:

I. Differences in Tooth Profile structure

Tooth profile ‌ ‌ features ‌ ‌ applicable working conditions ‌ ‌ typical equipment ‌

Straight-tooth type ‌ with straight tooth tops and uniform tooth grooves, suitable for loose soil and low-impact operations. Medium and small-sized excavators (such as PC60)

Conical tooth type ‌ with the tooth root gradually shrinking towards the top to form a wedge shape for medium-hardness soil, rock and frozen soil large loaders (such as XG953-Ⅲ)

Compound tooth profile ‌ helical tooth/hermetic tooth structure high-frequency heavy load, axial force resistance demand mining excavator (such as PC400)

Ii. Differences in Size Parameters

Grading of root opening size ‌

PC60 model: Tooth root opening 2.0mm (suitable for light-load bucket capacity)

PC200 model: Tooth root opening 4.0mm (standard for medium and large-sized equipment)

PC400 model: Tooth root opening 6.0mm (Special for super-large mining equipment)

Optimization of tooth length and thickness ‌

Extended extra sharp teeth ‌ : 20% longer than standard teeth, improving the efficiency of cutting into hard rock (such as Sany 55/60 models)

Thickened wear-resistant teeth ‌ : the back thickness of the teeth increases by 15%, and the bending strength is enhanced (XCMG 955 edge teeth)

Iii. Specifications of Functional Variants

Type: ‌ ‌ Core design: ‌ ‌ Performance advantages: ‌ ‌ Compatible models: ‌

Forged straight tooth ‌ straight tooth tip + forged base high cost performance and strong impact resistance PC60-PC300 series

Diamond reinforced teeth ‌ surface superhard alloy cladding enhances wear resistance by 40% sany SY75/95 series

The guard plate type edge teeth ‌ the integrated protective steel plate on the tooth side reduces the risk of bucket body deformation. Lingong 953/956 loader

Selection key ‌ :

Priority diamond teeth (anti-wear) for mine crushed stone working conditions

For the demolition of hard frozen soil, conical teeth or extra-sharp teeth (with enhanced cutting force) should be selected.

Recommended composite tooth profile for high-frequency operation equipment (noise reduction and vibration damping)
