March Loader Sales: Short-Term Pressure from the Pandemic Sends Sales Plummeting, but New Growth Drivers Are Already Emerging!

[Original article from China Construction Machinery Commerce Network] March data have been released: amid the pandemic, the sector faced short-term pressure, with loader sales plunging sharply. Meanwhile, electric loaders—tracked separately—have shown a markedly different sales trajectory. Against the backdrop of mounting downward economic pressures, electrified equipment has emerged as a new frontier for companies seeking to capture market share.

Hardware Analysis: Precautions for Bolted Joints in Mechanical and Electrical Equipment Installation

Bolted and nutted joints are among the most fundamental types of assemblies in the electromechanical industry. When these joints are tightened excessively, the bolts—subject to the combined long-term effects of mechanical and electromagnetic forces—are prone to metal fatigue, leading to loosening phenomena such as shear failure or thread stripping. This results in assembly looseness between components and can trigger accidents. In electrical engineering, for bolted and nutted connections carrying current, it is essential not only to consider their mechanical effects but also their electrothermal effects. If the connection is not sufficiently tight, contact resistance increases; during operation, this generates heat, which in turn accelerates oxidation at the contact surface, further increasing resistance—a vicious cycle that can ultimately lead to severe overheating, melting of the joint, and subsequent ground faults or open‑circuit failures. For primary equipment and busbars, parallel groove clamps, T‑type clamps, equipment clamps, and terminal lugs may all give rise to incidents of varying severity under such conditions.

Hydraulic pipe fittings are classified by thread type as: G threads and MT threads.

Hydraulic pipe fittings are classified by thread type as follows: G threads, ZG threads, NF threads, MT threads, and others. Sealing methods include hard sealing, O-ring sealing, and threaded sealing. Sealing configurations encompass internal conical 60° seals, 60° seals, UIC face‑to‑face 24° seals, and face‑to‑face ED seals. Z‑type threaded seals rely on tooth‑to‑tooth engagement for sealing, while the remaining types use parallel threads. Parallel threads do not provide sealing on their own; they primarily offer mechanical support, with sealing achieved via flat surfaces or end faces.
