Hand Brake Drum Lw321FLw300FZl30GMl333RN ZL20-030029

Product Introduction

This ZL20-030029 hand brake drum is a core friction component of the parking brake system for multiple XCMG wheel loader models including LW321F, LW300F, ZL30GM and L333RN. When the hand brake is activated, the brake shoes expand and press against the inner surface of the drum to create friction torque, locking the transmission output and keeping the machine stationary on slopes or during long-time parking.

The brake drum is cast from high-grade cast iron, featuring good rigidity, high thermal conductivity and stable friction surface. The inner working surface is precision machined to maintain smooth roundness, ensuring even contact with brake shoes and avoiding partial wear or grabbing during braking. Precisely positioned center bore and mounting holes guarantee accurate coaxial assembly. The robust structure can withstand repeated static braking loads and dissipate heat generated during emergency hand brake operation, resisting cracking and deformation under heavy working loads.

Manufactured strictly in accordance with OEM dimensional standards, this hand brake drum can directly replace original spare parts without modification. We supply OEM equivalent and premium aftermarket quality grades. Every finished drum undergoes dimensional inspection and inner surface quality check before shipment. Export-grade packaging and complete customs documents are available for overseas construction machinery repair shops and equipment distributors.
