产品名称 / Product Name

重型棘轮扳手   Heavy Duty Ratchet Wrench

产品简介 / Product Introduction

重型棘轮扳手是一种大扭矩、高效率的手动紧固工具，采用双向棘轮结构，可实现快速正反转，无需反复取下套筒即可连续拧紧或拆卸螺栓螺母。整体采用高强度合金钢材锻造，适用于重型机械、设备安装、汽修、钢结构、矿山、电力等工况下大规格紧固件的快速拆装，是工业现场与重型维修作业的必备工具。

Heavy-duty ratchet wrench is a high-torque and high-efficiency manual fastening tool. It adopts a two-way ratchet structure to realize quick forward and reverse rotation, enabling continuous tightening or loosening of bolts and nuts without removing the sleeve repeatedly. Forged from high-strength alloy steel as a whole, it is suitable for quick disassembly and assembly of large-size fasteners in heavy machinery, equipment installation, auto repair, steel structure, mining, electric power and other working conditions, making it an essential tool for industrial sites and heavy-duty maintenance operations.
