English EnglishComprehensive Vertical Access Equipment & Hoisting Systems
The LTD-P Series Electric Traction Hoists (500kg - 1000kg) are wire rope pass-through traction hoists engineered for safe, stable, and efficient vertical access. Designed for both man-riding applications and material lifting operations, this series is widely used in suspended platforms, suspended scaffolds, wind turbine service lifts, elevator installation platforms, and bridge or tower maintenance systems.
Unlike conventional lifting equipment that stores wire rope inside the machine, the LTD-P Series climbs and descends along the main steel wire rope. This pass-through traction structure allows unlimited working heights and longer lifting distances, making it an ideal choice for high-rise construction, facade maintenance, industrial access, and complex working-at-height projects. As a professional manufacturer of electric traction hoists, GREENCREST delivers reliable vertical lifting solutions for demanding global job sites.
The LTD-P Series combines a compact machine body, lightweight structure, reliable transmission system, and multiple safety protection configurations. Each hoist is designed to provide smooth lifting, controlled descending, and consistent traction performance under challenging working conditions. For contractors, rental fleets, equipment distributors, and maintenance teams, this series offers a dependable solution for suspended access and vertical lifting operations.
GREENCREST hoists are manufactured with high-precision machining processes and strict quality control. The series supports multiple voltage options and is suitable for a wide range of international construction and industrial environments. With CE certification by TÜV Rheinland and ISO 9001:2015 quality management, the LTD-P Series provides proven safety, durability, and long-term operating value.
To meet different load capacities and working conditions, the LTD-P Series is available in two main rope guidance structures: the Alpha design and the S-type design. Each configuration is optimized for traction stability, wire rope service life, and maintenance efficiency.
The Alpha wire rope path is used on the LTD-P500 and LTD-P630 models. This structure guides the rope through a compact single-loop traction path, reducing internal friction and minimizing wire rope wear. It is a practical solution for suspended platforms, facade access systems, and standard working-at-height maintenance tasks that require reliable lifting performance with lower machine weight.
The S-type rope path is used on the LTD-P800 and LTD-P1000 models. The wire rope passes through an S-shaped traction route across the drive sheaves, increasing the contact area and improving grip force. This design enhances traction power, reduces the risk of rope slippage, and provides stable lifting performance for heavy-duty suspended scaffolds, industrial platforms, and high-load vertical access systems.
| Model | Rated Lifting Capacity (kg) | Lifting Speed (m/min) | Motor Power (kW) | Wire Rope Diameter (mm) | Voltage Options | Unit Weight (kg) |
|---|---|---|---|---|---|---|
| LTD-P500 | 500 | 9.3 | 1.1 | 8.3 | 220V / 380V / 415V / 440V, 3-Phase | 45 |
| LTD-P630 | 630 | 9.3 | 1.5 | 8.3 | 220V / 380V / 415V / 440V, 3-Phase | 45 |
| LTD-P800 | 800 | 9.3 | 1.8 | 8.3 / 9.1 | 220V / 380V / 415V / 440V, 3-Phase | 52 |
| LTD-P1000 | 1000 | 9.3 | 2.2 | 9.1 | 220V / 380V / 415V / 440V, 3-Phase | 52 |
The LTD-P Series uses a wire rope pass-through traction system, allowing the hoist to climb and descend along the main wire rope without storing the rope inside the machine. This structure supports unlimited working height, long-distance lifting, and efficient operation on high-rise or large-scale maintenance projects.
A robust transmission system ensures stable lifting speed, consistent traction force, and dependable performance during repeated operation. The compact and lightweight design also improves on-site handling, installation efficiency, and maintenance convenience.
Safety is central to every LTD-P Series traction hoist. The equipment integrates key protection functions such as electromagnetic braking, controlled manual descent, and speed-limiting protection. These features help maintain safer operation for suspended platform users, maintenance personnel, and material lifting teams.
Critical internal components such as gearboxes, drive sheaves, and worm gears are produced with high-precision CNC machining. Accurate tolerances help reduce operating noise, improve transmission efficiency, support component interchangeability, and extend the service life of the hoist.
The LTD-P Series is suitable for a wide range of vertical access and lifting applications. Its stable traction performance and working-at-height safety design make it a preferred solution for suspended access systems and industrial maintenance equipment.
