Detailed Guide on the Correct Use of Construction Hoists

I. Basic Requirements for Operators (The "Human" Factor is Key) Certified Operation: Operators must undergo professional training and obtain a Special Operation Qualification Certificate for Construction (Construction Hoist Driver) issued by the housing and urban-rural development department or other authorized institutions. Operation without a certificate is strictly prohibited.

Research on Key Technologies of a New Energy-Efficient and High-Performance H-Type Construction Hoist

This paper addresses issues found in traditional construction hoists, such as eccentric structural defects, high vibration in the transmission system, susceptibility to wear, high overall energy consumption, and elevated costs. An H-type patented structure is designed, ensuring that the hoist as a whole is symmetrical front-to-back and left-to-right relative to the gear-rack meshing points on the guide rail, thereby eliminating unbalanced loading. Compared with similar types of hoists, this design offers enhanced safety, preventing tip-over accidents caused by unbalanced loading during construction, installation, and disassembly operations. Its advantages are even more pronounced in applications involving low-to-mid-rise buildings, prefabricated construction, and bridge construction projects.

Management of Construction Hoist Usage and Accident Prevention

In modern construction, construction hoists have been increasingly widely used due to their advantages such as smooth transmission, fast lifting, simple structure, and ease of use. However, due to construction companies' negligence regarding hoist safety issues and unscientific usage management, various safety accidents involving construction hoists are continuously increasing, drawing social attention. Therefore, relevant units must pay attention and actively take preventive measures for improvement and resolution.

Cause Analysis and Improvement Measures for Sway and Vibration Induced by Guide Rollers of Construction Hoists

In recent years, significant progress has been made in China's construction engineering sector. SC(D) series construction hoists, as commonly used construction machinery, play a vital role in building construction and related fields. However, during usage, a relatively common problem with construction hoists is the phenomenon of significant swaying and vibration during operation. This issue not only affects the comfort of operators but also hinders the long-term operation of the hoist, accelerates the wear rate of moving mechanical parts, reduces the service life of the machinery, and jeopardizes construction safety. The guide roller, serving as the connecting link between moving parts (such as the cage and transmission device) and fixed parts (such as the guide rail mast), if improperly adjusted or inappropriately constrained, inevitably becomes a major cause of sway and vibration in the hoist. Therefore, based on practical experience, this paper analyzes the structural characteristics of commonly used guide rollers in current construction hoists, seeks the causes of sway and vibration, and formulates corresponding improvement measures.
