Four-leg slings are often taken for granted as "sharing the load evenly across all four legs". Yet on-site measurements and general calculations show that under common conditions such as an offset centre of gravity, length tolerances between legs, and excessively large sling angles, only two or three legs are actually carrying the load, and the tension in a single leg can reach 1.5–2 times — or even more — the theoretical value for a vertical lift. When placing an order, the actual lifting weight must be stated clearly so that the configuration can be customized to suit that weight.

Ratchet load binders: a chain rated at 5 tonnes paired with a binder rated at only 2 tonnes — this kind of "spec mismatch" is not uncommon in export lashing orders.

Hebei Shengyu Hoisting a manufacturer of electric winches, produces complete-unit electric winches consisting of a waterproof receiver, pure-copper motor, clutch switch, wired and wireless remote controllers, manganese-steel hook and alloy-steel rope-guide.

Hebei Shengyu Hoisting manufacturer’s electric winches support horizontal pulling, inclined pulling and heavy-load lifting. Available in 12V, 24V and 48V voltages, they adopt pure-copper motors to deliver strong pulling and lifting force for various harsh working conditions.

Hebei Shengyu Lifting is a manufacturer specializing in small size electric winches. The winch supports both horizontal pulling and vertical lifting. It works with 12V, 24V, 48V power supply, and custom voltages are available for convenient and safe operation. It can be controlled by wired handle or wireless remote. So what specific functions does the clutch perform?

Four-leg slings consist of four G80 alloy steel chains that distribute load evenly through connecting links, with forged hooks fitted with safety latches at the ends, enabling multi-point balanced lifting in a single lift. Shengyu G80 chain slings are heat-resistant and wear-resistant; bulk purchases and long-term annual supply are both available. Inquiries, sample requests and orders are welcome.
