A New Benchmark for Heavy Paper Roll Lifting in Paper Mills: A Movable Hook Lifting Beam – Faster Hook Changes, Breakthroughs in Efficiency and Safety
In paper mills where heavy paper rolls often weigh several tons are being lifted, a lifting beam capable of "instant hook changes, precise adaptation, and safe and stable lifting" is becoming a core tool for breaking efficiency bottlenecks and safeguarding paper roll quality.
Technical Parameters:
| Lifting Capacity | 10 tons, 20 tons, 30 tons |
| Span | 2.5-6.0 m |
| Beam Material | The weld is made of Q460 high-strength low-alloy steel with a yield strength ≥460MPa, and the weld grade meets the first-class standard of GB/T 11345-2023. |
| Active Hook System | Equipped with quick-release forged hook connectors, compatible with GB/T 10051.2-2010 standard hooks, with a replacement time of ≤2 minutes |
| Adaptation Scenarios | Designed specifically for paper mills, this machine is suitable for hoisting various paper rolls (such as cultural paper, packaging paper, and specialty paper rolls) with diameters ranging from 1.2m to 3.5m and weights from 5 to 30 tons, covering the entire process from paper machine off-line loading to warehousing, stacking, and loading. |
I. Movable Hook Design: Zero Waiting Time for Hook Changes Across Different Paper Roll Sizes
Addressing the significant differences in paper roll diameter and weight in paper mills, this lifting beam utilizes a quick-release movable hook system – requiring no tools and simple operation to quickly switch between different hook sizes (compatible with 5-50 ton hooks). Whether it's a small paper roll with a diameter of 1.2m or an extra-large paper roll with a diameter of 3m or more, hook changes can be completed within 2 minutes, completely eliminating the pain points of time-consuming hook changes and poor adaptability of traditional lifting tools, making the paper roll transfer process "smooth sailing."
II. Heavy-Duty Lifting: Paper Rolls Remain Undeformed, Ensuring Safety
The main body of the lifting beam is forged from Q460 high-strength alloy steel, featuring a "box-type + reinforcing rib" structural design to ensure even stress distribution and maximum stability when lifting paper rolls weighing 10-30 tons. Actual measurements show that the radial deformation of the paper roll during lifting is <0.1mm, perfectly preventing wrinkles and damage caused by uneven stress, ensuring the quality of every roll remains "undamaged."
The movable hook is forged and heat-treated, with a breaking strength ≥5 times the rated load. Combined with an anti-detachment buckle design, it remains firmly locked even during the dynamic process of lifting and transferring paper rolls, eliminating the risk of "hooking off" at the source.
III. Exclusively for Paper Milling Scenarios: End-to-End Adaptation from Paper Machine to Warehousing
From the "paper roll unloading" at the back end of the paper machine to the "paper roll stacking and transfer" in the warehousing area, this lifting beam is a true "all-rounder" for paper mills:
Paper Machine Interaction: Precisely matches the paper machine's roll output rhythm, increasing lifting response speed by 40%, helping production lines operate at full capacity without interruption;
Warehouse Turnover: Adapts to warehouse layouts with different ceiling heights and aisle widths, working with overhead cranes to achieve efficient "three-dimensional" storage of paper rolls;
Logistics Loading: Quickly switches hooks to adapt to transport vehicles, doubling the efficiency of paper roll loading and unloading, and directly compressing the logistics cycle.
In the competitive logic of the paper industry, where "efficiency is king and quality is fundamental," this movable hook lifting beam is both an "efficiency accelerator" (fast hook changing, fast transfer) and a "quality guardian" (no paper roll deformation, zero lifting risk). Choosing it means equipping the paper mill's heavy paper roll lifting with a "dual engine of efficiency and safety," making every lifting a key step in "cost reduction and quality improvement."
