Construction Hoist Tiltable Loading Surface Gap Bridging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction hoists require custom walkways to bridge varying distances between loading and unloading surfaces, which is inefficient and costly, especially in shipbuilding where deck dimensions differ, leading to wasteful disassembly and reassembly of equipment.
Innovation Solution
A construction hoist with load-bearing columns and a lifting unit that can slide and tilt, allowing the loading surface to adjust its position to bridge gaps of varying lengths without the need for custom walkways, utilizing anchorage means, lifting motors, pinions, and movement racks to facilitate movement and tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If custom walkways are built to bridge varying distances between loading and unloading surfaces, then the gap can be bridged for specific applications, but the device becomes complex and requires disassembly/reassembly for different applications
Solution Approach 1:
The support structure is made tiltable about a tilting axis, allowing it to dynamically adjust its orientation. This enables the loading surface to be positioned at different angles to bridge varying gap distances without requiring custom walkways for each application, thereby reducing device complexity while maintaining adaptability.
Solution Approach 2:
The hoist system is designed with a tiltable support structure that can accommodate multiple gap distances and configurations using the same basic components. This universal design eliminates the need for application-specific custom walkways, allowing the same hoist to serve multiple functions across different applications.
2Manufacturing precision
If custom steelwork walkways are constructed for specific applications, then the gap can be bridged accurately, but time is lost during disassembly and reassembly for subsequent applications
Solution Approach 1:
The tiltable support structure allows rapid adjustment of the loading surface position and angle to match different gap distances. This dynamic capability enables the same hoist to be quickly reconfigured for subsequent applications without time-consuming disassembly and reassembly of custom walkways, while maintaining manufacturing precision through standardized components.
3Device complexity
If the loading surface is fixed in position, then the structure is simple, but it cannot accommodate varying distances and deck dimensions
Solution Approach 1:
The support structure incorporates a tilting mechanism that allows the loading surface to be positioned at different angles and distances. This dynamic capability provides adaptability to varying gap distances and deck dimensions while maintaining relative structural simplicity through the use of a single tilting axis and standardized components.

AI summary
A construction hoist (12) adapted to be coupled to a structure comprises at least one load-bearing column (14, 16) arranged on an anchorage side (18) with anchorage means (20) adapted to anchor said at least one load-bearing column (14, 16) to a structure. The construction hoist (12) further comprises a lifting unit (22) provided with a loading surface (24) and a support structure (26) for the loading surface (24). The lifting unit (22) is adapted to slide along the at least one load-bearing column (14, 16) along a direction (X). The construction hoist (12) further comprises movement means (28) adapted to allow the sliding of said loading surface (24) with respect to said support structure (26) in a direction (Y) substantially transverse to the direction (X), between a retracted or rest position, and an extracted position in which said loading surface (24) protrudes from said support structure (24) on the anchorage side (18).
