FAQs: Hoists and Winches for Industrial Use

The manual chain block utilises a hand chain for the operator to manually lift the load whereas an electric chain hoist is fully powered with an electric motor and no manual effort is required. The electric hoist does require a power supply.

The mechanics inside are similar however a chain block is designed to lift vertically whereas a lever block is designed to be used horizontally and vertically. There are a few chain blocks that can be used outside of the 5 degrees of vertical but manufacturer user guides must be followed.

Chain blocks come standard in 3m and 6m height of lift. Ranger can offer other height of lifts as required.

This is a feature that is available in some brands of chain and lever blocks to prevent the user from overloading the block.

Most common chain blocks do not allow for overhead or side use as the design limitation of the hand/pocket wheel does not allow for it. The Yale 360 handwheel rotates a full revolution allowing the user to use from all angles.

The IP rating is a weather protection rating. IP means ingress protection and is shown, for example, as IP55. The first number relates to dust protection. 5 means the unit is sealed to prevent sufficient dust entering the hoist which could interfere with normal operation. The second number relates to water ingress. A rating of 5 stipulates the hoist is protected against low-pressure water jets from all directions.

Chain cannot be joined together to extend the lift height of any hoisting product. To satisfy this requirement, a new length of chain must be purchased and fitted by a competent person. It then needs to be tested to ensure the product has been assembled correctly and recertified.

Yes. The motor power can be disconnected from the main power supply in an emergency.

Yes. Electric Hoists are available in many different lift heights to suit your requirements. However be sure to take note of it’s duty cycle, they are prone to overheat when used excessively or with longer lengths. Another type of hoist may be a better option.

Yes, for Electric Hoists that are rated IP55 or IP65. This means they have protection from direct jet spray and dust particles. They also have a strong epoxy coated painted body and the load chain is Nickel-plated, which is corrosion and abrasion-resistant. However to better protect the hoist in external applications extra weather cover is recommended.

Yes. However the feature required to do so is not standard so an Electric Chain Hoist needs to upgraded to meet the requirements of Australian Standard AS 2550.
