BOB-LIFT
BOB-LIFT is one of the professional 4 Ton Knuckle Boom Truck Mounted Crane manufacturers and suppliers in China. We are willing to work hand in hand with every customer for mutual benefit and development. Over the years, we have been focusing on research in the field of 4 Ton Knuckle Boom Truck Mounted Crane. With rich experience and professional technology, we have established our own BOB-LIFT brand in China and have achieved good response. Our products are durable and easy to maintain, favored by domestic and foreign customers.
| Product Parameters (SQ4ZA2) | |
| Max Lifting Capacity | 4000kg |
| Max Lifting Moment | 8.4ton.m |
| Recommend Power | 14KW |
| Hydraulic System Flow | 25L/Min |
| Hydraulic System Pressure | 26Mpa |
| Coil Tank Capacity | 60L |
| Installation Space | 850mm |
| Self Weight | 1250kg |
| Rotation Angle | 400° |
1. Advanced development & analysis make sure design is very reliable
2. Using two-section telescopic cylinder design, one of the cylinder push the second large boom, another cylinder push the rest of the telescopic boom by the pulley block
and wirerope. To ensure that the crane has strong lifting capacity in the middle distance and effectively protect the wire rope in the boom.
3. The more symmetrical center design of pentagon & hexagon boom make it has bigger anti-bending capacity.
4. The boom interface is made of strong steel plate, and the U-shaped arm is used for the crane above 8T, which makes the cross-section bending resistance stronger.
5. The crane above 6.3T adopts square legs, which can better protect the cylinder.
6. Compact boom head and tail design, make the boom length to reach maximum, prolong the working life of hydraulic system.
7. The integer lifting winch improved the working efficient greatly and prolonged work life of hydraulic system.
8. Integral boom hear structure with more strength. Boom head adopting integral structure, greater intensity. Split head design reduces the boom head carrying capacity.
9. Lifting mechanism hydraulic winch relies on disc spring and friction brake, stable and reliable, efficient, low noise, small calorific value; Rely on hydraulic balanced valves balancing weights when falling, greatly improve product reliability.
10. Ati-slewing impulse equipment that make vehicle running safely.
11. Water-based paint, more environmentally friendly.
