In the installation of elevators in old residential areas, narrow passages and dense pipelines have long constrained construction efficiency. Recently, the LEAD SKYLIFT mini mast type aerial work platform broke through the encirclement in the renovation of an old residential area in a city center. With its ultra narrow body, fully electric silent operation, and millimeter level precise control, it successfully solved the industry problem of "equipment cannot enter or expand" and was praised by the construction party as the "key man" in elevator installation.

Ⅰ、 Pain Point Focus: "Space Dilemma" in the Renovation of Old Residential Areas

The old residential area in the city center was built in the 1990s, and the installation of elevators faces three major challenges:

1. Extremely narrow passage: The distance between buildings is only 3 meters, and traditional equipment cannot turn. The narrowest part of the pedestrian passage is less than 1.8 meters;

2. Complex underground pipelines: gas, water pipes, and cables are densely distributed, and equipment needs to be precisely avoided;

3. Impact on residents' daily lives: During the construction period, it is necessary to ensure that residents can travel normally, and strict requirements are placed on noise and dust control.

The project manager admitted, "In the past, when encountering such tunnels, we could only rely on manual scaffolding, which was inefficient and had high safety risks

Ⅱ、 Breaking Force: Three Major Breakthroughs of Mini Mast Platform

In response to the above challenges, the LEAD SKYLIFT LSDM080 mini mast platform demonstrates excellent adaptability:

1. Ultimate passability

① The body width is narrow and can be accessed through standard unit doors and narrow corridors;

② The four-wheel steering system achieves zero turning radius and allows for free turning in the tunnel;

③ The overall weight of the machine is ≤ 800kg to avoid putting pressure on old underground structures.

2. Precise and safe operations

① The maximum load of the platform is 200kg, supporting 2 workers to carry tools for synchronous operation;

② Electro hydraulic proportional control achieves ± 5mm micro motion accuracy, perfectly avoiding pipeline dense areas;

③ Dual hydraulic safety lock+tilt alarm system ensures stable operation in sloping environments.

3. Green construction mode

① Fully electric drive, operating noise<58dB, equivalent to normal conversation sound;

② Zero emissions and zero hydraulic oil leakage, residents do not need to temporarily relocate during the construction period;

③ Quick disassembly and assembly design, capable of completing the relocation of 3 buildings in a single day.

Ⅲ、 Technology Extension: Innovative Functionality Adapts to Special Scenarios

To solve the special challenges in elevator installation, the equipment has also demonstrated multiple innovative applications:

1. Pipeline avoidance mode: By installing ultrasonic detectors, automatically identify pipelines within 0.5 meters underground and mark safe operation areas;

2. Micro vibration welding: The platform is equipped with an active shock absorption system to ensure arc stability during high-altitude welding, with a weld qualification rate of 99.99%;

3. 24/7 adaptability: With a protection level of IP54, it can operate continuously in light rain weather, ensuring maximum project duration.

Ⅳ、 Industry value: redefining the standards for old and renovated equipment

This case brings three inspirations to the field of urban renewal:

1. Economic breakthrough: The equipment rental cost is only 70% of the scaffolding solution, but the overall efficiency has increased by over 50%;

2. Standard upgrade: It has been included in the recommended equipment catalog for the renovation of old residential areas in multiple regions;

3. Mode innovation: We have pioneered the old to new model of "micro devices+modular construction", which has been promoted in 8 cities.

When the tentacles of urban renewal penetrate deep into the forgotten narrow alleys of the times, the LEAD SKYLIFT mini mast platform proves through technological innovation that true engineering wisdom does not lie in conquering the sky, but in being adept at every inch. It is not only the "key master" of the old renovation project, but also the promoter of countless residents' "direct happiness".
