Yale CPV Electric Chain Hoist with Push Beam Trolley

Standard CPV and CPVF Features

• Classification 1 Am/M4. For 1-phase hoists: 1 Bm/M3. As required (with appropriate changes to lifting capacity resp. duty cycle), the model CPV can also be reclassified up to 3m/M6.
• Main contactor as standard, for increased safety.
• Increased operating safety through 42V LVC (low voltage control), push-button pendant control, IP 65.
• 360-day warranty (excluding wear parts) and a lifetime lubricated gearbox.
• The electromagnetic spring pressure brake holds the load safely even in the event of power failure.
• Motor protected to IP 55 (acc. to VDE 0530), against ingress of dust and water jets.
• The easily adjustable slip clutch is designed to guarantee a permanent connection between the load and the brake.
• The standard, oil-bath-lubricated and case-hardened gearbox has a helical gearing for particularly smooth running and enhanced lifetime. The models CPV/F 2-8 and 5-4, CPV 2-4 and 5-2 as well as CPV/F 25-8 and 50-4 have a sealed gearbox with lifetime lubrication.
• All-steel chain guide. The models CPV/F 2-8 and 5-4 as well as CPV 2-4 and 5-2 have a thermoplastic (POM) chain guide that is integral to the housing.

Optional CPV Features

• Stainless steel load chain (no reduction of working load limit).
• Stainless steel load hooks for single fall hoists.
• Food industry-approved gearbox lubricants.
• For a suspension hook or lug, see the hook suspended Yale CPV.
• Electric travelling trolley: see the Yale CPV with electric beam trolley.
• Flexible chain container.
• Other operating voltages.
• Counter for operating hours and number of starts.
• Radio remote control.
• Control for synchronized operation of several hoists.
• Festooned cable systems and alternative power supplies.
• Suspension for light crane systems.

Yale CPV and CPVF Hoists: What's the difference?

The difference is quite simple. The Yale CPV is a single-speed electric hoist, whereas the CPVF or CPV/F is twin/dual speed with 1 fast speed and 1 slow speed, which makes the CPVF more suited for positioning applications where a slower speed is a necessity.

What the lifting speeds depend on the hoist's capacity. e.g. the 1-tonne single fall unit with dual lifting speeds would have a fast speed of 8 m/min and a slow speed of 2 m/min, whereas the 2-tonne CPVF would have a 4 m/min fast speed and a 1 m/min slow speed. In this instance, the reason for the lifting speeds being halved between the 1-tonne, 1-fall unit and the 2-tonne, 2-fall unit is that the base unit is the same, but the bottom hook block is replaced with a 2-tonne hook which allows the load chain to be reeved back to the hoist body effectively doubling the capacity of the 1 tonne 1 fall CPV, but this also halves the lifting speed.

Looking at the table below, you will see other instances of this. e.g. 250kg 1-fall is also the base unit for the 500kg 2-fall version (again with the bottom hook block replaced with a 0.5t one).
