Frequently asked questions

  • 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 P Series comes with plastic packing that can be placed under the foot-plates to accommodate height differences at each end of the container.

  • WHAT CONTAINER TYPES AND SIZES DO THEY LIFT?

    The P Series can be used to lift any length of container; 10’, 20’, 40’, 48’, 53’ and even 60’. Rigging and hydraulic hoses for 20' containers are supplied as standard. Extension rigging and hoses are supplied as an optional accessory for longer containers. If you plan to lift longer containers, just let us know.

  • DO THEY LIFT HIGH-CUBE CONTAINERS?

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

  • WHAT IS THE LIFT CAPACITY OF THE P SERIES?

    The C-Lift P32 has a rated lift capacity of 32 tonne (70,000 lb).

    The C-Lift P10 has a rated lift capacity of 10 tonne (22,000 lb).

  • HOW MANY PEOPLE ARE NEEDED TO OPERATE C-LIFTS?

    The C-Lift P Series can be safely operated by two trained operators. Some of the tasks (for example the set-up) can be completed more efficiently if more people are available. It is possible for one person to operate the C-Lift P10, but this involves heavy-lifting and increases the time to complete a lift. A chain block is a useful accessory for quickly and safely lifting heavier components.

  • HOW LONG DOES IT TAKE TO SET UP AND LIFT OR LOWER A CONTAINER?

    The operating time for the P Series depends on many factors, including: (i) experience and number of operators, (ii) size of the container, and (iii) site conditions. 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 30 - 40 minutes with the C-Lift P Series.

  • HOW HIGH IS THE CONTAINER ELEVATED?

    The C-Lift P 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 P Series, there is a 25 cm (10 in) gap between the C-Lift legs and each side of the trailer. That is 50 cm (or 20 in) overall.

  • ARE THEY 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% of their rated load before leaving the factory. Safety Notices and a Safety Checklist are clearly marked on all legs and the HPU. A sturdy rigging system is integrated into the design, increasing stability. The hydraulics feature abrasion resistant hydraulic hoses. Integrated counter balance valves (in the hydraulic cylinders), ensure 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 P SERIES POWERED?

    The P Series runs off a single phase electrical power supply. This powers a hydraulic power unit that supplies hydraulic oil to each leg. 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.

    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)?

    The P Series could be run off a truck's PTO. Contact us to discuss the power options that best suit your operations.

  • CAN I USE MAINS POWER SUPPLY?

    Yes, the C-Lift P Series hydraulic power unit can be run from the mains electrical supply, as well as a portable generator. Options are available for 230 VAC and 115 VAC.

  • WHAT MAINTENANCE IS REQUIRED?

    The P Series' mechanical hardware is designed to be tough and durable, and requires very little maintenance. All metallic parts are zinc-plated (silver) for corrosion protection.

    The hydraulic system should be maintained as per standard practice. Hydraulic seals should be replaced when there are signs of leakage, and hydraulic fluid should be replaced or filtered periodically. The hydraulic hoses may need to be replaced if they are damaged (for example, if they are driven over by a vehicle). This maintenance can be performed by your local hydraulics service agent.

    The C-Lift Operating Manuals contain a comprehensive list of maintenance items to monitor: (i) before use, (ii) during operation, (iii) every quarter (or 250 lifts), and (iv) every year (or 1,000 lifts).

  • 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.
