NLB45 Top Type Hydraulic Breaker
NEWLAND Top Type hydraulic breaker — representative image
The NEWLAND NLB45 Top Type hydraulic breaker has a 1.2–3.0 Ton reference excavator range, requires 20–40 L/min oil flow and uses a 45 mm tool. Check the upper mounting dimensions and total attachment weight for the configuration you plan to order.
Housing: Top Type
Carrier range: 1.2-3.0 Ton
Required oil flow: 20-40 L/min
Tool diameter: 45 mm
Excavator ranges and hydraulic specifications are NLB series reference values. Confirm the complete Top Type assembly and attachment mass for your carrier.

NLB45 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 | 1.2-3.0 Ton |
| Complete assembly operating weight | Confirm the Top Type assembly weight |
| Required oil flow | 20-40 L/min |
| Setting pressure | 150 bar |
| Operating pressure | 90-120 bar |
| Impact energy | 271 J |
| Impact rate | 700-1200 blows/min |
| Hose diameter | 1/2 inch |
| Tool diameter | 45 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 NLB45 fits in the Top Type range
NLB45 covers a 1.2–3.0 Ton carrier interval. It overlaps NLB40 from 1.2 to 2.5 Ton and NLB53 from 2.5 to 3.0 Ton. NLB45 requires 20–40 L/min, between the different 15–30 L/min and 25–50 L/min ranges of those neighbours. All three share the listed 90–120 Bar series operating-pressure range, so a pressure match alone does not resolve the choice. For the Top Type arrangement, confirm the complete attachment load and mounting interface against the selected carrier after screening these model references.
Check the hydraulic specifications
The supplied NLB series reference lists 90–120 Bar operating pressure and 150 Bar setting pressure for NLB45. Operating pressure and setting pressure serve different purposes. Use the applicable installation procedure for any hydraulic adjustment. Impact energy is 271 J, impact rate is 700–1200 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.

NLB45 Top Type questions
Why does a Top Type NLB45 inquiry need mounting measurements?
The 1.2–3.0 Ton series carrier interval does not define an excavator’s connection geometry. Include the upper bracket interface and any quick coupler details so the proposed Top assembly can be checked alongside the circuit and load limits.
