A hydraulic breaker is not an attachment you bolt on — it is a power tool married to a carrier, a hydraulic circuit and a rock face, and every mismatch in that marriage is paid in cracked housings, cooked oil and hours the production schedule never recovers. This guide covers the SDLG E6700HB breaker the way the machine actually works: carrier matching, oil flow and pressure, tool selection, rock assessment and the production matching breaker economics that decide whether breaking earns its place on the programme — ending in the pre-delivery compatibility and commissioning checklist the brief demands.
Quick answers if you are specifying now: the breaker's weight must sit inside the carrier's safe handling envelope, its hydraulic appetite inside the circuit's honest delivery, and its tool inside the rock's character — with everything verified against official documentation before anything ships. Machine context sits in the E6700HB specs, price and applications guide, the rock methods in the E6415H rock excavation guide and the method alternatives in the rock excavation methods guide; the desk at +254 718 686 967 runs the compatibility check against the serial before quotation.

Carrier matching: the weight conversation
The discipline of breaker carrier matching starts with weight, because weight is the failure mode that punishes fastest. A breaker too heavy for the carrier beats the boom, the pins and the mounting every operating hour; too light and the tool bounces instead of penetrating, converting diesel into noise while the rock wins. The match is verified against official data: the breaker's operating weight against the carrier's safe handling envelope at the mounting points, and the carrier's own class against the tool it is asked to carry. For hydraulic breaker selection at this scale, the desk confirms the pair from the serial — the carrier's documentation and the tool's documentation speaking to each other in writing, because the marriage certificate is also the warranty file.
Hydraulics: flow and pressure, honestly delivered
The second match is hydraulic, and the numbers that matter are oil flow pressure breaker honesty: the circuit's actual flow and pressure at the working ports, not the pump's nameplate. An underfed breaker runs slow and hot — the oil ages, the seals follow, and the tool spends its life at half stroke. An overfed one — where pressure spikes beyond the tool's relief — beats its own housing to failure. The matching rows: required flow within the circuit's delivery at working engine speed; operating pressure within the tool's design envelope; correct relief settings; and the return line configured so oil returns cool and clean. These are commissioning measurements, not brochure figures — made at the first start and recorded in the machine's file.
Tool selection: the working end decides the day
The tool is where the rock meets the marriage, and E6700HB tool selection follows the rock and the duty: pointed tools for penetrating and fracturing, blunt tools for breaking oversize and secondary work where the material must shatter rather than split, and chisel variants for trenches and controlled edges. The disciplines that protect any tool choice: correct tool-to-bushing fit, checked and greased on the schedule; operating the tool at the angle the rock demands — perpendicular for penetration, not prying sideways where the steel snaps; and stopping before the blank-firing point, where the tool strikes without load and the energy returns into the machine. Tool consumption is a cost line the rock writes — the assessment below decides what it will say.
Rock assessment: the production question
The discipline of rock assessment breaking is the economics of the whole method, and it is done face by face. The rows: hardness and continuity — sound granite argues differently from weathered seams; fracture state — already-fractured material breaks in a fraction of the blows continuous rock demands; scale — the boulders and edges that suit breaking versus the continuous faces that argue for drilling and blasting instead; and location — breaking earns its premium exactly where blasting cannot go: near structures, pipelines, live facilities and the secondary pile. The production matching breaker arithmetic follows: cubic metres per hour at the assessed resistance, against the same production carried by a blast — with the permissions included in the comparison, honestly. The methods guide works that comparison in full; this page's point is narrower — the breaker wins where the assessment says it wins, and loses politely where it does not.
The pre-delivery compatibility and commissioning checklist
The breaker commissioning checklist below is attached to the order and scheduled into the delivery — the two moments the whole programme depends on:
| Stage | The rows that must pass |
|---|---|
| Compatibility, before order | Breaker weight within carrier envelope; flow and pressure within circuit delivery at working speed; mounting interface correct; relief settings defined in writing |
| Pre-delivery | Tool and bushing fit verified; hoses and fittings matched; documentation pack complete — carrier, tool and circuit data together |
| Commissioning, first start | Flow and pressure measured at the working ports; relief settings confirmed; tool greased and fitted; operator walkthrough on blank-firing limits and working angles |
| Records | All measurements entered in the machine file — the warranty document and the tool-life baseline in one record |
Misuse patterns that punish breaker programmes
- Weight mismatch: the oversize tool beating the carrier, or the undersize one bouncing at the rock's patience.
- Hydraulic hopeful thinking: flow and pressure assumed, not measured — slow tools and cooked oil as the receipts.
- Blank firing: the tool striking without load, returning its energy into its own housing.
- Side prying: the tool used as a lever where the steel was built to strike.
- Skipping the checklist: compatibility assumed at order and commissioning skipped at delivery — the two moments the whole programme depended on.
Five checks before the breaker is ordered
- The carrier envelope is confirmed: breaker weight verified against the carrier's documentation for the serial.
- The hydraulics are measured, not assumed: flow and pressure at working ports, with relief settings in writing.
- The tool matches the rock: pointed, blunt or chisel per the assessment, with fit and bushing verified.
- The production arithmetic is run: cubic metres per hour against the alternatives, permissions included.
- The checklist is on the order: compatibility, pre-delivery and commissioning rows attached to the quotation.
Working the knowledge with the desk
For hydraulic breaker Kenya buyers ready to specify: send the site's rock, production target and constraints to +254 718 686 967 and the desk returns the breaker programme — compatibility confirmed against the serial, the checklist scheduled into the delivery, and the production arithmetic run against the alternatives. The SDLG E6700HB price Kenya position is quote-only against that programme — the machine is not on the October 2026 published price list — with the tool, the commissioning and the training in the same written quotation. Hydraulic breaker Kenya buyers have no shortage of tools to choose from; the disciplined ones own the ones whose weight, hydraulics and tools match their rock — and the checklist above is the difference between the two.
Frequently asked questions
1. What is the SDLG E6700HB?
A dedicated breaker excavator in the heavy class — the machine built for sustained breaking duty, with its figures on the protected page and its matching rules in this guide.
2. How is the breaker matched to the carrier?
By weight against the carrier's safe handling envelope for the serial, hydraulics against the circuit's measured delivery, and mounting interface against the documentation — all confirmed before order.
3. Which tool suits our rock?
Pointed tools for penetration and fracturing, blunt tools for breaking oversize, chisel variants for trenches and edges — chosen from the rock assessment, never from habit.
4. What do flow and pressure decide?
Everything the tool does: underfed breakers run slow and hot, overfed ones beat their own housings — both are commissioning measurements recorded in the machine file.
5. When does breaking beat blasting?
Where the rock is manageable in scale and the location restricts blasting — near structures, pipelines and live facilities — with the production arithmetic run honestly against the alternatives.
6. What is blank firing and why does it matter?
Striking without load — the tool's energy returns into its own housing and the carrier; it is avoided by working angles and stopping points the operator is trained on.
7. What does the E6700HB cost in Kenya?
Quote-only — not on the October 2026 published price list; machine, tool, commissioning and training in one written quotation within 24 hours.
8. Who runs the compatibility check for our machine?
