Wall Mounted Jib Crane With Electric Hoist Free Standing Low
clearance 3000kg
1. Drive mode: electrification is the only option (and requires
high power):
Lifting mechanism:
Wire rope electric hoist: mainstream choice (2-ton or 3-ton class).
Provide sufficient lifting force, speed and height (usually ≥10
meters). Heavy deadweight, to be included in the total load.
Heavy chain electric hoist: Also available, but the lifting speed
is slower, and chain management is more troublesome at super-high
heights.
Slewing mechanism: Must be electrically driven! Equipped with a
high-torque slewing motor and reducer. Under a 2-ton load, it is
completely unrealistic to manually push the cantilever to rotate.
2. Safety requirements reach the highest level:
Overload protection (load limiter): Absolutely necessary and
requires redundant design. This is the last line of defense to
prevent catastrophic accidents.
Multiple braking system: hoist main brake + auxiliary brake (even
double auxiliary brake).
Travel limit: Accurate and reliable upper and lower limit switches.
Emergency stop: Emergency stop buttons are set in multiple places.
Slewing limit and buffer: Precise electric limit (180° range) and
hydraulic/spring buffer.
Structural health monitoring (optional but recommended): Consider
installing strain gauges to monitor stress in key parts.
Design specifications: Strictly comply with the highest standards
such as GB/T 3811 "Crane Design Specifications", and take the upper
limit of the safety factor.
Special equipment supervision: Rated lifting capacity ≥ 1 ton must
be included in the special equipment management. Strict design
document review, installation supervision, comprehensive load test
(1.25 times static load, 1.1 times dynamic load), and regular
inspection are required.
Operator qualification: Must be certified and receive special
training for this special equipment.
3. Application scenario (extremely rare):
In heavy industrial plants, special workstations close to
ultra-thick concrete core tubes/shear walls are used for fixed-mode
lifting of heavy objects below 2 tons (such as the only maintenance
point for specific large equipment).
Special experimental facilities (such as large wind tunnels and
heavy test benches) are located on the edge of specially reinforced
walls.
Extremely rare, and usually due to historical reasons or special
conditions that cannot be replicated.
4. Operation and control:
Wireless remote control: Essential and the only recommendation. The
operator must be able to control the equipment (lifting, rotation,
emergency stop) at a safe distance and optimal viewing angle, away
from hanging objects and potential danger areas (such as walls in
case of failure).
5. Cost and implementation complexity:
Sky-high cost: The equipment itself is expensive, but the greater
cost lies in:
Comprehensive structural assessment and reinforcement design fees.
Engineering costs for large-scale wall reinforcement (may far
exceed the equipment price).
Professional design, inspection, supervision and inspection, and
evidence collection costs for special equipment.
Professional installation and commissioning costs.
