Right Angle Spiral Bevel Gearbox for Elevating Systems<\/h1>\n

Elevating and lifting systems impose unique demands: high sustained axial loads, frequent start-stop cycles, and the critical requirement that no drive failure causes an uncontrolled load drop. The EVER POWER right-angle spiral bevel gearbox for elevating applications is engineered with oversized tapered roller bearings, reinforced shaft journals, and conservative service factor calculations for vertical lifting duty.<\/p>\n

Product Overview<\/h2>\n

This variant is optimized for vertical lifting: electric hoists, goods elevators, stage counterweight systems, and scissor lift drives. The housing incorporates additional ribbing for torsional stiffness, and shaft bearings are selected for combined radial and heavy axial load capacity. All units are supplied with an inspection certificate confirming load test results. Applications:<\/strong> Electric hoists | Industrial elevators | Scissor lifts | Stage machinery | Mining shaft drives<\/p>\n

How It Works<\/h2>\n

The motor drives the input shaft horizontally. The spiral bevel gear set redirects power 90 degrees to a vertical output shaft connected to a cable drum or chain sprocket. The gearbox provides speed reduction (1.5:1, 2:1, or 3:1) between motor and drum, increasing output torque while reducing drum speed to a safe operating level. The spiral tooth profile’s gradual engagement is especially valuable during load engagement when instantaneous torque peaks can be 3-5x the running torque.<\/p>\n

Core Advantages<\/h2>\n
\n
▲ Heavy Axial Load Capacity<\/strong><\/p>\n

Oversized tapered roller bearings on the vertical output shaft handle sustained suspended loads without deflection.<\/p>\n<\/div>\n

🔴 3x Shock Rated<\/strong><\/p>\n

Spiral tooth geometry absorbs start-stop and load engagement peaks; rated to 3x nominal torque.<\/p>\n<\/div>\n

📈 Reinforced Housing<\/strong><\/p>\n

Additional ribbing and wall thickness for torsional rigidity under suspended load.<\/p>\n<\/div>\n

📋 Load Test Certificate<\/strong><\/p>\n

Every unit tested and certified before shipment. Essential for lifting equipment compliance.<\/p>\n<\/div>\n

✅ CE Compliant<\/strong><\/p>\n

CE documentation for Machinery Directive compliance for European lifting equipment certification.<\/p>\n<\/div>\n<\/div>\n

Structure and Material Details<\/h2>\n

Housing: ductile iron (GGG50) for maximum impact resistance. Output shaft: 42CrMo, sized for rated axial load with minimum safety factor 2.5 on yield. Bearings: matched pair of tapered roller bearings in face-to-face arrangement for bidirectional axial load capacity. Sealing: labyrinth seal plus double-lip contact seal on output shaft. Oil: AGMA 8 (ISO VG460) mineral standard; synthetic EP optional.<\/p>\n
