Hydraulic demolition shears also called demolition crusher,multi-processor,etc.It’s composed with main body, hydraulic cylinder, movable jaw .The external hydraulic system
offer hydraulic pressure for the hydraulic cylinder to make the two movable jaws open and close to achieve the effect of crushing concreted walls
1. Mainly function is for both primary and secondary demolition work.
2. It’s low noise, no vibration, meet the requirements of environmental protection, which are Suitable for city and high-tech zone demolition project.
1. Our demolition shear,both the main-body and jaws are made from hardox450.
2.We use boring machine adjust the precision after welding,to avoid the big tolerance leaded by welding
3.The 2pcs jaws is made from 50mm thick hardox450 steel,much more longer life than cast jaw.
4.The blade of this demolition shear,can cut 30mm-diameter steel rod,can cut 20mm-thick steel sheet.
5. Blade is 2pcs 4-side blade,so have a much more longer life
6. Hydraulic oil cylinder is equipped with a protective cover to obstruct the splash of
concrete and steel debris
7.The grease injection nipples have cover protected,won’t be damaged in rough
9.We have test this products many years,it’s high performance,durable,convenient to operate, it’s a proven technology.
