Frequently Asked Questions

  • Does the C-Lift A Series provide a container weight and VGM?

    Yes, we can fit the C-Lift A Series with sensors that wirelessly transmit the load on each leg to the VGM App. The App displays the gross container weight (or VGM) on your smartphone. The VGM App can also confirm the container's load distribution and allows users to take photos, record essential shipment details, email a signed VGM certificate and log a detailed digital container weight record.

    This weighing instrumentation is an optional extra. It is not "legal-for-trade" approved. However it does provide an accurate container weight to within +/- 2%. Whether you can use this weight indication for SOLAS VGMs depends on the VGM rules in your country. Contact us and we will help you answer this question in your country. 

  • How much space is needed beside the container for the A32 to operate?

    The A32 requires a minimum of 1.5 metres space beside the container, and to be comfortable 1.8 metres is fine.

  • Can the A32 be stored outside?

    Yes, the A32 could be stored outside. We would recommend storing it under covers when not in use, to help protect it from rain, dust and UV. BISON can supply good quality zip-on, canvas as an optional extra if required. 

  • What ground surfaces does the C-Lift work on?

    The ground surface must be solid, stable and compacted. Test by lifting the container a short, safe height. If you have any doubts about the ground bearing capacity, use additional steel plates to spread the load over the ground.

  • How level does the ground have to be?

    The site should ideally be level (within about 2°), however C-Lifts can accommodate ground with a small degree of unevenness. The A Series has an articulated footplate, simple wedges and a levelling indicator, so users can achieve perfectly vertical lifting and a stable base.

  • What container types and sizes do they lift?

    The A Series can be used to lift any length of container; 10’, 20’, 40’, 48’, 53’ and even 60’. Longer electric cables are required if you want to lift containers longer than 40'. If you plan to lift longer containers, let our team know when you speak with them.

  • Do they lift high-cube containers?

    Yes, our C-Lifts can lift 9'6" high-cube containers.

  • What is the lift capacity of your C-Lifts?

    The C-Lift A32 has a rated lift capacity of 32 tonne (70,000 lb).


  • How many people are needed to operate C-Lifts?

    The C-Lift A Series can be safely operated by one trained operator. Container transfers can be completed more quickly if more people are available.

  • How long does it take to set up and lift or lower a container?

    The operating time for the A Series depends on many factors, including: (i) experience and number of operators, (ii) size of the container, (iii) site conditions, and (iv) available power supply. As a general indication, the entire process - to position the C-Lift, attach to container, lift container, move truck and lower container to ground or chassis - will take two operators 15 - 20 minutes with the C-Lift A Series. 

  • How high is the container elevated?

    The C-Lift A Series elevates the container to a maximum height of 165 cm (65 in). We can manufacture and supply taller lifting legs on special request.

  • What is the gap between each leg and the container?

    For the C-Lift A Series, there is a 25 cm (10 inch) gap between the C-Lift and the tyres of the trailer. That is 50 cm (or 19 inches) overall.

  • Are these C-Lifts safe?

    All C-Lifts are safe, provided the recommended operating instructions are followed. We recommend all operators are trained in how to use BISON C-Lift equipment prior to using it. Like all material handling equipment, C-Lifts present risk if not used properly. Safety ultimately relies on the care and competence of the operators.

    BISON supplies a comprehensive Operating Manual and Training Videos (with subtitles that auto-translate in all languages) detailing essential safety information. All legs are made from high strength steel and proof tested to 150% their rated load before leaving the factory. Safety Notices and a Safety Checklist are clearly marked on all legs. The hydraulics feature integrated counter balance valves, which ensures the container will not fall unexpectedly in the event of a hose burst or electrical failure.

  • What is stopping the trailer from hitting the legs?

    Provided the driver is competent and takes reasonable care, the risk of the trailer hitting the legs can be safely managed. The following basic steps are recommended in the operating and training material:

    1. Only use the C-Lift on sites where the truck and trailer can line up directly with the elevated container.
    2. Check that the container is sufficiently elevated before moving the vehicle under the container.
    3. Make sure no twist locks are protruding from the trailer.
    4. Drive slowly.
    5. Always use an observer or "spotter", in communication with the driver.
    6. Use reversing aids, such as simple visible lines on the ground and/or reversing cameras if desired
  • Do I need any special training to operate C-Lifts?

    For safety reasons, we recommend that only trained personnel use your C-Lifts. BISON provides detailed Operating Manuals and Instructional Videos for training purposes.

  • How is the C-Lift A Series powered?

    The A Series runs off a single phase electrical power supply. This powers a hydraulic power unit on each leg and the electronics to keep the lifting cylinders moving synchronously. Electric cables connect the four legs. The electrical power source can be a nearby mains supply, or a portable generator. Electrical power can also be taken from the truck batteries, using an inverter to convert the DC power to AC.

    The wireless remote for controlling the C-Lift has an internal rechargeable battery.

    Alternative power options are possible. Contact us to discuss the power options that best suit your operations.

  • Can I run the C-Lift off my truck's power take off (PTO)?

    No, the A Series runs off its own hydraulic power unit which needs to be electronically controlled to ensure synchronous motion of the lifting cylinders.

  • Can I use a mains power supply?

    Yes, the C-Lift A Series is designed to be run from the mains electrical supply as well as a portable generator. Alternative options are possible. Contact us to discuss the options that best suit your region and operation.

  • What maintenance is required?

    The A Series is designed to be tough and durable, and relatively low maintenance. The wire-rope lifting cables are the only component that needs regular inspection and lubrication. Depending on how frequently and how heavily the C-Lift is used, the seals and wear bands on the hydraulic cylinder may require periodic replacement. Servicing is straightforward and BISON carry a full range of parts if the need arises.

  • What is the expected lifecycle?

    The design life is 10 years. Provided the equipment is well looked after and properly maintained, it will deliver many years of service.
