Overhead bush hammer RSI
Le problème
Ceiling manual bush hammering: 15 m/s² vibration plus raised arms, shoulders out within 2 h.
Sept Tools
Gazelle or Eland trolley: 0.42 m/s², zero felt weight, full day compliant.
Sept Tools
Strain-free ceiling bush hammering
Two equivalent brushless sets for ceiling bush hammering: Gazelle with IU33 Longopac and Fouine XB165, or compact Eland with Fouine. Built-in class H extraction, native strain relief.
Ceiling bush hammering combines the strain of overhead work with that of manual bush hammering. Raised arms, machine weight, vibration, dust falling straight back onto the operator: impossible to sustain over a full day without dedicated equipment. Sept Tools offers two brushless ceiling sets equivalent in throughput. The Gazelle set (Gazelle + IU33 Longopac + Fouine XB165) for standard sites with built-in class H extraction. The compact Eland set (Eland + Fouine) for sites constrained on size. Both deliver native strain relief that lets the operator hold a full shift.

Challenges and solutions
Technical challenges and answers
Noise in operating car park
Le problème
Covered car parks and active tertiary: 90 dB(A) hammer banned, immediate complaints.
Sept Tools
Brushless 60 dB(A) plus class H extraction: permanent cohabitation with users.
Falling fines on operator
Le problème
Ceiling bush hammering: silica fines fall on face, OEL exceeded in minutes.
Sept Tools
IU33 Longopac HEPA H13 source capture 65 l/s: exposure divided by 50.
Class M insufficient overhead
Le problème
Class M vacuum overhead: partial capture, OEL 0.1 mg/m³ not met.
Sept Tools
Class H HEPA H13 built into Gazelle set: compliance without external addition.
Bulky trolley blocked
Le problème
Corridors, door frames, low height: bulky trolley cannot pass.
Sept Tools
Compact Eland set IP65: 800 mm standard clearance, 1600 W constant torque.
Double fleet capital tied
Le problème
Two dedicated ceiling machines: capital doubled, x14+ payback not reached.
Sept Tools
Versatile Fouine XB165: 2-min drum swap, x14+ lifespan on both uses.
Use cases
For which job sites?
Anti-condensation paint adhesion
Covered car park ceilings and technical rooms: bush-hammered profile for the adhesion of technical anti-condensation paints. Higher durability versus grinding.
Architectural exposed-concrete finish
Exposed concrete ceilings in contemporary architecture: revealed aggregate effect, a finish sought in hospitality and premium tertiary.
Roughness for covered car parks
Creation of a non-slip profile on the soffit to limit slippage of suspended technical elements. A durable integrated solution.
Insulating resin preparation
Mechanical adhesion for sprayed insulation resins or technical coatings applied to ceilings. A reproducible CSP 5-7 profile.
Frequently asked questions
Your questions, answered
What is the difference between the Gazelle set and the Eland set?
The Gazelle set (Gazelle + IU33 Longopac + Fouine XB165) bundles class H extraction as standard: ideal for sites where silica compliance is critical. The Eland set (Eland + Fouine) is more compact and easier to handle on sites constrained on size: the class H vacuum is connected separately.
Why use the Fouine rather than a dedicated bush hammer?
The versatile Fouine XB165 lets you chain grinding and bush hammering on the same site with a simple drum swap. For a ceiling contractor, a single versatile machine is more profitable than a fleet specialised by use.
Can grinding and bush hammering be chained on the ceiling?
Yes. The Fouine XB165 accepts the grinding drum and the bush hammering drum. The swap takes under two minutes. The operator chains both operations on the same site without changing machine or trolley.
Which extraction for ceiling silica compliance?
The IU33 Longopac class H HEPA H13 is integrated into the Gazelle set. It complies with the French OEL of 0.1 mg/m³ for crystalline alpha-quartz silica. In Eland configuration, the IU33 is connected separately.
Which size to choose for a constrained site?
The Eland set is designed for low ceiling heights and restricted access. Its compact size lets it pass through standard corridors and door frames. The Gazelle set is bulkier but bundles the vacuum.
