Dimensions H 315 mm × W 430 mm × C 540 mm, weight approx. 5 kg. It is directly applied to hoists, cranes, and lifting systems to weigh the suspended load in real-time, with a digital LED display for immediate reading. Suitable for warehouses, workshops, loading\/unloading sites, and checking loads on jib cranes or winches.

The typical application is in-line suspension with hoists, jib cranes, winches: the instrument is placed between the lifting system and the load to read the actual weight lifted in real-time. For weighing packages, containers, mechanical components, and light materials in artisan workshops and small-medium warehouses. The large-digit LED display allows weight readings even from a distance during loading operations, a crucial feature for construction site applications or warehouses with reduced visibility. The typical battery life is 50-70 hours of actual use. In Krollit customers' laboratories, the CW 500 is chosen by mechanical workshops for checking the weight of lifted parts, logistics warehouses for weighing suspended packages, carpentry shops for verifying the weight of structures, and construction sites for checking loads during crane handling.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\n\u003cp\u003eThe Bernardo CW hook dynamometer range is organized into 7 models ordered by capacity and accuracy: CW 500 (500 kg, ±0.2 kg), CW 1000 (1,000 kg, ±0.5 kg), CW 2000 (2,000 kg, ±1 kg), CW 3000 (3,000 kg, ±1 kg), CW 5000 (5,000 kg, ±2 kg), CW 10000 (10,000 kg, ±5 kg), CW 15000 (15,000 kg, ±5 kg). Absolute accuracy decreases with increasing capacity, but percentage accuracy remains constant (approximately 0.03-0.05% of full scale).\n\nThe CW 500 model is entry\/mid-range. For workshops with typical loads under 800 kg, the fine accuracy (0.2 kg) is correctly sized. For larger loads, choose higher models: CW 2000 for up to 2,000 kg, CW 3000 for up to 3,000 kg, etc.\n\nDifference from the Bernardo ID series: CW are electronic dynamometers FOR WEIGHING; ID are mechanical hooks FOR LIFTING (without weight measurement). For mixed lifting + weighing applications, use a CW; for lifting only, IDs are significantly more economical.\u003c\/p\u003e\n\u003ch3\u003eKrollit Logistics and Support\u003c\/h3\u003e\n\u003cp\u003eBernardo shipping in 5-9 business days (7 days for Southern Italy).
