150x60x1400 Shaft Mounted Forks

The weight of a single 150x60x1400 axle-mounted fork is 139 kg. The cross-section is 150 mm wide, 60 mm thick, and the total length is 1.4 meters. The fork sleeve and fork body are precision turned after integral die forging. A bidirectional sinusoidal oil groove is machined into the inner hole of the sleeve. With a high-pressure centralized lubrication system, each injection of grease can evenly cover the entire length of the sleeve along the oil groove, forming a complete oil film during heavy-load rotation. The fork surface adopts a variable-pitch transverse tooth pattern design, and the tooth pitch is doubled near the fork tip, which can effectively prevent the end from slipping when pushing pulp bales or cotton bales. The end face of the shaft sleeve is equipped with a mechanical cumulative rotation counter, which beats a number every time it rotates. When the specified life is reached, a red replacement warning sheet will automatically pop up. Replaceable tungsten-cobalt alloy shovel teeth are welded under the fork tip. The shovel teeth have an eagle-beak-shaped hook tip and are specially used to pry heavy-duty skids or steel ingots from the ground. After the tooth body is worn, the wedge pin can be loosened and replaced with a new one.

 

 

Each fork is machined with a stress groove with gradually varying depths on the back of the fork, and the bottom of the groove is rolled and strengthened to guide bending fatigue cracks to a safe area. The surface treatment uses low-temperature vulcanization and molybdenum disulfide impregnation. The friction coefficient is lower than 0.08 and has the ability to self-repair micro-scratches. The shaft sleeve locking nut adopts a hydraulic pre-tightening structure. It is pressurized to the specified pressure by a manual pump and then locked. The pre-tightening force is accurate and repeatable. Before leaving the factory, conduct a temperature field test on the bushing under 1.35 times the rated load, and the temperature rise shall not exceed 35 degrees Celsius. This fork is adapted to the 4A-level shaft mounting system. There is no need to disassemble the shaft end baffle when replacing it. You only need to loosen the two quick-locking nuts to extract it axially. With a single weight of 139 kg and quick-hang lifting rings at both ends of the shaft sleeve, a single person can complete the installation in three minutes using a balancing crane.
