• High-strength alloy steel: built for repeated impacts at 1.200 bpm. The Brewer excavator hydraulic hammer is made of alloy steel specially selected for resistance to the repeated dynamic stresses of hydraulic percussion. The hammer body, the piston and the chisel are dimensioned to withstand thousands of impact cycles per hour without cracking or deformation, ensuring the service life required for intensive use in quarries, demolition and road construction.
• Impact frequency 400–1.200 blows/min: adaptable productivity. The Brewer excavator hydraulic hammer covers a wide range of impact frequencies: the small models for 1–5 tonne excavators reach 1.200 blows per minute on brittle materials and light concrete, while the large models for 40–60 tonnes operate at 400–600 blows per minute with proportionally higher impact energy for hard, compact rock. The optimal frequency for the material to be broken is selected at quotation stage.
• Chisel 40–210 mm: diameter selected for the application. The Brewer excavator hydraulic hammer uses chisels with a diameter of 40 mm on the light models for precision work, up to 210 mm on the heavy models for breaking massive rock blocks. The chisel is the hammer's primary wear component, replaceable independently and available in stock at UZINEX Iași. Different tip geometries (conical chisel, flat, cross) are selected according to the material and the geometry of the work surface.
• Low vibration level: protecting the excavator and the operator. The Brewer excavator hydraulic hammer has a design specifically intended to minimise the transfer of vibration from the impact head to the excavator arm and the operator's cab. Reduced vibration extends the service life of the excavator arm joints, reduces operator fatigue over long shifts and allows more extensive use of the hammer on excavators with structural-stress monitoring systems.
• Silent type: sound-insulated housing, optional. The Brewer excavator hydraulic hammer is available in the Silent type version with a sound-insulated housing, which significantly reduces the noise level emitted during percussion. The quiet version is mandatory for use in urban areas with noise restrictions and recommended for any site near residential buildings or institutions sensitive to noise pollution.
• Safety valve for hydraulic system protection: on the relevant models, the Brewer excavator hydraulic hammer includes a safety valve that prevents damage to the excavator's hydraulic circuit when the rated working pressure is exceeded. This protection is essential when the chisel jams in the material or when the operator maintains percussion on a surface without penetration, situations that generate dangerous pressure peaks without a protection valve.
“This protection is essential when the chisel jams in the material or when the operator keeps the percussion going on a surface without penetration.”
• Easy lubrication: fast on-site maintenance. The Brewer excavator hydraulic hammer has the lubrication points of the chisel and the guides accessible directly from the side of the hammer, without removing the housing. Frequent lubrication of the chisel is essential for the service life of the guides and the impact surface; the lubrication interval and the type of grease are specified in the user manual supplied on delivery.
• Compatible with 1–60+ tonne excavators: the complete range of machines. The Brewer excavator hydraulic hammer covers everything from ~1 tonne mini-excavators used in interior selective demolition and utility work to ultra-heavy 60+ tonne excavators in industrial quarries and major infrastructure projects. UZINEX engineers select the right model for your excavator's tonnage class.
• 60-month UZINEX warranty: chisels and spare parts in stock at Iași, national technical support within a guaranteed 24–48 hours.
Main applications of the Brewer excavator hydraulic hammer
Demolishing concrete and masonry structures is the classic application of the Brewer excavator hydraulic hammer. Foundations, load-bearing walls, reinforced concrete columns and massive masonry structures that cannot be sectioned with a hydraulic shear or pulled apart with a bucket require fragmentation through percussion before removal. The Brewer excavator hydraulic hammer fragments concrete and masonry to transportable sizes with the minimum number of passes compared with alternative manual or mechanical techniques.
Breaking massive rock in quarries and surface mining operations is the second major application. Rock blocks too large to be loaded directly or too compact to be excavated with a bucket require prior fragmentation with the Brewer excavator hydraulic hammer. On rock of medium hardness (limestone, sandstone), the excavator hydraulic hammer is complementary or an alternative to explosives for the controlled fracturing of quarry faces.
Road construction and rehabilitation frequently require breaking the degraded concrete or asphalt layer and the consolidated foundation substrate before rebuilding the road structure. The Brewer excavator hydraulic hammer fragments the concrete layer to processable sizes, which can then be loaded and transported or sorted with a rotary screening bucket for reuse.
Excavating foundations in hard and rocky soils, required for the construction of buildings on ground with a rock substrate at shallow depth, is a frequent application in Romania in sub-mountain and Carpathian areas. The Brewer excavator hydraulic hammer pre-fragments the rock layer before excavation with the bucket, eliminating the need for explosives in urban or residential areas.

Application dedicated to flows with constant quality requirements.
Opening tunnels and underground works are a specialised application where the Brewer excavator hydraulic hammer works in complement with the Monde MD excavator drum cutter : the hydraulic hammer pre-fragments the localised hard zones in the profile, while the drum cutter mills the regular profiles. The combination of the two attachments covers both homogeneous rock and zones with large variability in hardness. The Brewer excavator hydraulic hammer vs. the MD drum cutter: when to choose each
The Brewer excavator hydraulic hammer and the Monde MD excavator drum cutter are both attachments for attacking hard rock and concrete, but with completely different working principles and application profiles.
The Brewer excavator hydraulic hammer works through repeated percussion: a chisel strikes the material 400–1.200 times per minute, producing cracking and fragmentation through the propagation of shock waves. It is the optimal solution for the rapid fragmentation of hard materials in large volumes, for localised demolition and for breaking rock without the need for a precise excavation profile.
The Monde MD excavator drum cutter works through the continuous abrasion of the toothed drum: it produces a smooth, precise excavation profile, without shock waves. It is the solution when the geometry of the excavation matters (tunnels, diaphragm-wall foundations, profiled channels) and when control of vibration takes priority over raw fragmentation speed. Frequently asked questions about the Brewer excavator hydraulic hammer
How long can the Brewer excavator hydraulic hammer run continuously?
The Brewer excavator hydraulic hammer is designed for intensive use, but the manufacturers recommend periodic breaks to prevent overheating of the hydraulic oil and the piston. The general rule is a maximum of 30 seconds of continuous percussion on the same spot, alternating with repositioning. Continuous use without repositioning prematurely wears the chisel and the guides. UZINEX engineers specify the correct operating regime during the training included with delivery. What types of chisel are available for the Brewer?
The Brewer excavator hydraulic hammer uses chisels in three main geometries: conical (for penetration into rock and compact concrete), flat (for scaling and finishing surfaces) and cross (for stratified rock, which cracks more easily with the cross-shaped tip). UZINEX engineers recommend the right geometry for your specific application at quotation stage. The chisels are available in stock at Iași. Does the Silent type version significantly reduce noise?
Yes, the sound-insulated housing of the Silent type version of the Brewer excavator hydraulic hammer reduces the noise level by 10–15 dB(A) compared with the standard version. This reduction is significant perceptually (the noise seems 3–4 times quieter) and allows compliance with the noise limits imposed in urban areas during permitted working hours. UZINEX confirms the availability of the Silent type version for the chosen model at quotation stage. Is the Brewer excavator hydraulic hammer eligible for public tenders?
Yes. UZINEX provides the complete technical documentation on delivery. The Brewer excavator hydraulic hammer can be added directly on SEAP/SICAP. UZINEX is a member of the Enterprise Europe Network and supplies equipment for European-funded projects in the infrastructure and construction sector.
