Heli 3.5T Hinged Fork Carriage MJ-D30B8-31101 — OEM HELI Forklift Maintenance Part

The HELI hinged fork carriage MJ-D30B8-31101 is an OEM-grade replacement carriage assembly for HELI 3.5-ton counterbalance forklifts. Constructed from carbon steel with a weight of 51kg and package dimensions of 150×89×53cm, this is a substantial structural component designed to replace worn, bent, or damaged original carriages in HELI H2000, G-series, and K-series forklifts operating in building material, manufacturing, and industrial environments. The hinged fork mount design allows each fork to pivot independently around the hinge axis, improving load engagement on uneven surfaces and reducing the risk of fork-tip damage to pallets and goods during entry. As a direct OEM replacement for part number MJ-D30B8-31101, this carriage requires no modification to the mast, hydraulic connections, or fork mounting — it bolts directly into the HELI 3.5T mast assembly using the factory mounting points. CE and ISO certified, with OEM, ODM, and customization services available for non-standard requirements.

Replacing a hinged fork carriage on a HELI 3.5T forklift is a heavy maintenance procedure best performed during scheduled downtime. The 51kg carriage weight requires mechanical lifting assistance — a workshop crane or second forklift is essential for safe removal and installation. Before disassembly, lower the mast completely and relieve all hydraulic pressure. Remove the forks and fork pins first, then unbolt the carriage from the mast roller assembly. Inspect the mast roller channels for wear and replace any rollers showing flat spots or excessive clearance — installing a new carriage on worn rollers transfers alignment problems and accelerates wear on both components. During installation, verify that all mounting bolts thread freely before applying torque; cross-threading a carriage mounting bolt into the mast bracket is a common workshop error that requires helicoil repair. After installation, mount the forks and cycle through full lift and tilt range to verify clearance with the mast, backrest, and overhead guard. The most common cause of repeat carriage failure on HELI 3.5T models is uneven fork loading — always center loads on the carriage and distribute weight evenly across both forks to prevent asymmetric hinge wear.
