The safety cylinder that prevents catastrophic boom over-tilt. At 590 kg, the anti-tilt cylinder is the second-heaviest cylinder in the truck crane family \u2014 mounted between the crane superstructure and the boom base. It limits the boom’s backward tilt angle, preventing the boom from folding over the back of the crane during luffing operations. A failure of this cylinder can result in boom collapse.<\/p>\n

How the Anti-Tilt Cylinder Prevents Boom Over-Rotation<\/h2>\n
<\/div>\n

\"Truck<\/p>\n

During crane luffing (raising the boom angle), the boom can reach a position where gravity reversal occurs \u2014 the boom’s centre of gravity passes over the pivot point, and the boom would accelerate backward uncontrollably. The anti-tilt cylinder acts as a hydraulic backstop, absorbing the boom’s energy and limiting the maximum backward angle.<\/p>\n

The extreme rod-to-bore ratio (\u03a6160\/\u03a6190 = 84.2%) tells the engineering story: this cylinder works primarily in tension \u2014 pulling against the boom to resist backward tilt. The thick \u03a6160 rod provides the tensile strength needed to restrain a boom that can weigh tens of tonnes, while the relatively narrow annular area limits the oil volume for controlled energy absorption.<\/p>\n

The 4,300 mm installation distance and 1,400 mm stroke span the full angular range of the boom \u2014 from working position to maximum safe backward angle. The cylinder must be long enough to accommodate the full arc of boom rotation without bottoming out. Browse the full mobile machinery hydraulic cylinder<\/a> range.<\/p>\n<\/section>\n

Why 590 kg? The Engineering of Heavy-Duty Safety<\/h2>\n
<\/div>\n
\n
\u03a6190 Bore for Massive Restraining Force<\/strong><\/p>\n

At 20 MPa, the \u03a6190 bore produces approximately 567 kN (57 tonnes) of restraining force \u2014 enough to arrest a multi-tonne boom that is accelerating backward under its own weight.<\/p>\n<\/div>\n

84.2% Rod Ratio for Tensile Strength<\/strong><\/p>\n

The \u03a6160 rod resists the full boom load in tension. The thick-wall rod prevents buckling and provides the structural integrity needed for this safety-critical function.<\/p>\n<\/div>\n

4,300 mm Overall Length<\/strong><\/p>\n

The cylinder spans from the superstructure to the boom base \u2014 a distance that increases as the boom tilts backward. The 1,400 mm stroke accommodates the full range of safe boom angles.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
