At Bauma Shanghai 2018, TONKEE highlighted three key product lines tailored for excavators:
CATERPILLAR-Replacement Piston Pumps: Engineered to match OEM performance, these pumps feature high-strength alloy casings and precision-machined plunger sets, ensuring 92% volumetric efficiency and resistance to 35MPa pressure. They seamlessly replace CAT pumps in models like 320D and 336D, reducing downtime for excavation and hydraulic systems.
Swing Motors: Designed for smooth rotation and high torque (up to 18,000N·m), these motors integrate dual - brake systems and wear - resistant seals, enabling precise 360° operation in tight spaces. Compatibility with CAT excavator swing mechanisms ensures minimal installation adjustments.
CAT-Replacement Engine Parts: Including forged pistons, cylinder liners, and crankshafts, these components meet or exceed CAT’s material standards (e.g., HRC58–62 hardness for pistons). They are rigorously tested for durability in high - temperature/high - load environments, suitable for engine overhauls in 3126 and C7 series engines.
By presenting these solutions, TONKEE underscored its commitment to delivering cost - effective, reliable alternatives for excavator maintenance, addressing industry demands for efficiency and affordability at the premier Asian construction expo.
