NLB68 Top Type Hydraulic Breaker
NEWLAND Top Type hydraulic breaker — representative image
The NEWLAND NLB68 Top Type hydraulic breaker has a 4–7 Ton reference excavator range, requires 40–70 L/min oil flow and uses a 68 mm tool. Check the upper mounting dimensions and total attachment weight for the configuration you plan to order.
Housing: Top Type
Carrier range: 4-7 Ton
Required oil flow: 40-70 L/min
Tool diameter: 68 mm
Excavator ranges and hydraulic specifications are NLB series reference values. Confirm the complete Top Type assembly and attachment mass for your carrier.

NLB68 model reference specifications
These figures are NLB series reference values for initial model comparison. Request the total operating weight for the quoted Top Type assembly, including the mounting components and tool.
| Specification | Series specifications / configuration notes |
|---|---|
| Suitable excavator range | 4-7 Ton |
| Complete assembly operating weight | Confirm the Top Type assembly weight |
| Required oil flow | 40-70 L/min |
| Setting pressure | 170 bar |
| Operating pressure | 110-140 bar |
| Impact energy | 677 J |
| Impact rate | 500-900 blows/min |
| Hose diameter | 1/2 inch |
| Tool diameter | 68 mm |
Carrier weights use the catalog unit “Ton.” Confirm the unit basis when comparing them with your excavator specifications. Setting pressure and operating pressure are separate fields. Use the specification and mounting drawing for the quoted assembly to check the final installation.
Where NLB68 fits in the Top Type range
NLB68 is a 4–7 Ton carrier reference, overlapping NLB53 from 4 to 4.5 Ton and NLB75 from 6 to 7 Ton. At exactly 7 Ton, NLB85 also enters the carrier comparison. NLB68 lists 40–70 L/min, NLB75 lists 50–90 L/min and NLB85 lists 60–100 L/min. The correct Top Type shortlist therefore depends on usable circuit delivery as well as the carrier interval. Identify the proposed upper mounting assembly and check its dimensions and complete load before treating any shared carrier figure as a confirmed match.
Check the hydraulic specifications
The supplied NLB series reference lists 110–140 Bar operating pressure and 170 Bar setting pressure for NLB68. Operating pressure and setting pressure serve different purposes. Use the applicable installation procedure for any hydraulic adjustment. Impact energy is 677 J, impact rate is 500–900 Bpm and hose diameter is 1/2 Inch. Use the series figures to compare models, then request the specification and installation details for the Top Type assembly being quoted.
Confirm the Top mounting package before ordering
Ask for the Top upper mounting drawing with the carrier connection dimensions identified. Include any quick coupler interface in that review. The photo illustrates the Top Type housing. Request a dimensioned drawing for the model you plan to order. Request the complete quoted assembly weight, including the proposed mounting components, and compare it with the permitted attachment load of the carrier. Keep the selected working tool and hose connections in the same package description so the quotation covers the installation being considered.

NLB68 Top Type questions
Is NLB68 automatically the Top Type choice for a 7 Ton carrier?
No. NLB75 and NLB85 also include that carrier figure in the series references. Their hydraulic requirements differ. Confirm usable circuit delivery and the actual Top assembly’s mounting dimensions and total weight before choosing.
