For which jobs are demolition jaws best suited?

Techna demolition jaws are an indispensable attachment in modern construction and demolition work. Thanks to their versatility and powerful working capabilities, they are increasingly becoming an essential piece of excavator equipment on both large construction sites and smaller engineering projects.

Demolition of reinforced concrete structures

One of the main applications of the demolition jaws is the demolition of reinforced concrete structures - walls, foundations, columns or floor slabs. Thanks to their high crushing force and cutting blades, these jaws make it possible to effectively crush and separate reinforcement from concrete, eliminating the need for several separate tools.

Cutting steel structures

Jaw versions equipped with strong cutting blades can easily handle steel beams, trusses or pipes. They are used when dismantling industrial halls, bridges or other structures made of metal.

Recycling and cleaning work

Demolition jaws are also suitable for use in recycling facilities and loading bays. They allow efficient segregation and processing of scrap metal and construction materials from demolition, which increases the profitability of the work and reduces logistical costs.

Urban demolition

Thanks to their compact design and high operating force, the demolition jaws are ideally suited to work in densely built-up urban areas. They can be used wherever traditional demolition methods - such as dynamite or heavy equipment - are too dangerous or inapplicable.

Specialist applications

Demolition jaws are also used in specialised applications - for example in building disasters, rescue operations or the rapid demolition of life-threatening structures. Their precision and ability to react quickly make them indispensable in emergency situations.

Techna Poland offers crushing and demolition jaws to suit different classes of excavators - from compact urban machines to heavy construction equipment. Our products are distinguished by their durability, cutting power and ease of installation.

How to select the right demolition jaw model for the scope of work and weight of the excavator

HRP400

The HRP400 model is a compact and lightweight demolition jaw designed to work in confined spaces - ideal for urban demolition and recycling. They are great for dismantling lightweight concrete structures, removing masonry units or cutting fine rebar. With a weight of 630 kg and a cutting force of 120 tonnes, they are efficient and precise. Compatible with 6-11 tonne excavators such as Kubota KX080, JCB 100C-2, Takeuchi TB290 or Volvo ECR88. It is an excellent choice for companies involved in building redevelopment and urban adaptation.

HRP600

The HRP600 is a versatile model designed for medium-duty demolition work. With a cutting force of 200 tonnes and a closing force of 140 tonnes at the rear of the jaws, it can shred load-bearing walls, reinforced concrete beams or bridge elements without any problems. It will prove its worth on medium-scale construction sites and in the demolition of residential and industrial buildings. It is designed for excavators weighing 12-17 tonnes, such as the CAT 315, Komatsu PC138, Hitachi ZX135US or Doosan DX140LC. It is a reliable tool for crews working on complex site upgrades.

HRP800

The HRP800 is designed for demanding tasks on large construction and industrial projects. With a cutting force of 240 tonnes and a large jaw range, it is ideal for crushing massive reinforced concrete blocks, demolition of bridges, viaducts and infrastructure structures. With a weight of 2456 kg, it requires the use of 18-26 tonne excavators such as the Hyundai HX220L, Volvo EC220E, Komatsu PC210LC, Liebherr R920. The HRP800 is the choice for companies working on infrastructure projects that require reliability and strength.

HRP1000

The heaviest of the series - the HRP1000 - is a professional tool for the toughest demolition tasks. With a massive cutting force of 300 tonnes and a closing force of 240 tonnes, the jaws can handle massive steel and reinforced concrete structures. Ideal for the demolition of large industrial halls, factories or railway infrastructure. Works with 27-38 tonne excavators such as CAT 330, Volvo EC350E, Doosan DX300LC, Hitachi ZX350LC. It is the choice for professionals who need maximum performance and durability.

Summary

Techna's demolition jaws are robust attachments for excavators from 6 to 38 tonnes, designed for intensive demolition work. Depending on the model (HRP400-HRP1000), they offer a cutting force of 120 to 300 tonnes and different ranges of closing force for efficient concrete crushing and rebar cutting. The models also differ in their oil flow requirements, ranging from 250 l/min on the smallest model to 400 l/min on the largest. Thanks to the wide range of parameters, the Techna jaws can be precisely matched to the specific type of excavator and the nature of the work to be performed. It is the ideal solution for companies looking for durable and efficient equipment for industrial, infrastructure and urban demolition.
