Tangye’s hydraulic jacks are in daily use throughout the world working efficiently for customers who require jacks for a variety of applications from supporting bridges to lifting the nose end of F16 fighter planes.
Tangye jacks are used by the following industries – construction, industrial, automotive, mining, railroad and manufacturing.
All Tangye Hydraulic Jacks are built with the following characteristics:
Portable
Extensive use of high strength aluminium alloys has minimised jack weight for improved portability.
Reliability
All moving parts are totally enclosed and lubricated by the hydraulic oil. Seats are highly resistant to deterioration under widely varying climatic conditions. Their long working life make Hydralite jacks the choice of many rental operations.
Safe – Overload Protection
A high pressure relief valve prevents lifting of loads in excess of the jack’s capacity while locking overloads applied to the ram
Overstroke Protection
Hydralite jacks are fitted with a fail-safe positive stop mechanism which prevents overstroking of the ram by venting oil to the reservoir when the stroke limit is reached.
Load Sustaining
Jack models incorporating a threaded ram and load retaining ring, model – SR, should be selected when loads are to be sustained for a significant time. No need to rely on hydraulic fluid pressure.
Quality Assurance
Every jack is serial numbered, fully tested and certified.

The following are some guidelines on the safe use of winches when used for lifting:
Always:
- Store and handle winches correctly.
- Inspect the winch, rope and accessories before use and before placing into storage.
- Ensure mounting and suspension points are secure and suitable for the full loads that will be imposed.
- Lift the load just clear, halt for a short period to ensure the integrity of the brake or sustaining mechanism before completing the lift.
- Use a speed appropriate to the specific application.
- Keep hands and feet clear of ropes, drums etc.
Never:
- Raise loads by revolving the drum in the opposite direction to that indicated.
- Use winches with loose or insecure handles.
- Use the pawl to arrest descending loads.
- Use winches if the rope is twisted or trapped.
- Over wind the rope on or off the drum.
- Use winches for man-riding applications unless they are specifically designed for that purpose.
Storing and Handling Winches
- Never return damaged winches, ropes etc to storage. They should be dry, clean and protected from corrosion.
- With winches used for temporary applications, remove the rope for separate storage or wind it fully onto the drum and lash in position to prevent damage.
- With winches left in situ, remove pulleys etc and wind the rope fully onto the drum. Where this is not possible, pulleys etc should be positioned to protect them from damage and so as not present a danger to persons or other equipment. Isolate any power supply.
Regularly inspect the winch and, in the event of the following defects, refer the winch to a Competent Person for thorough examination: mounting insecure; loose or missing bolts; winch frame distorted; rope drum flanges chipped or cracked; rope anchorage loose or pulled; ratchet or pawl worn; brake worn or slipping; rope worn, or winding incorrectly; broken wires; gears worn, or not positively locating; any other visible damage, corrosion, defects or operational faults.

Driving on soft sand is not the easiest thing to do but with some preparation and safety tips can be an enjoyable and fun experience in your 4×4.
- As soon as the surface gets softer than a road select the 4×4 drive. Then, when leaving the sand, don’t forget to switch the 4×4 off again. If you don’t do that, it will put stresses on the driveshaft, gearbox and transfer cases as well as cause unnecessary and uneven tyre wear.
- Always reduce the tyre pressure just before going on the sand. This will influence your vehicle performance as the more air you let out, the more tyre will be on the sand, and the better flotation you’ll get.
- If you are afraid to drive on the soft sand, drive on the hard sand just next to the water. It’s worth remembering, though, that patches of soft sand might be found everywhere.
- One of the most common mistakes while driving on sand is to use high gear without leaving any reserve. This will most probably caught you stuck in the sand. If you use lower gear, you can respond more quickly.
- If you start getting stuck, don’t rev the power and dig a bigger hole. Try to stop the vehicle and reverse out on a fresh track.
- Drive off slowly only if all four wheels are safe on the firm sand.
- Try to avoid driving your 4×4 in the sea. It will deteriorate your vehicle quickly even if you give it a rinse afterwards. Another thing is you can sink easily when you stop in the water.

Lifting beams, frames and spreaders are usually designed and built
for a specific purpose. The range of designs and capacities is therefore only limited by practicality. When selecting the beam to be used you need to plan the lift taking the following into account:
Application requirements:
- to reduce headroom, provide multiple lift points,
- to provide adjustable lifting centres,
- to handle out of balance loads,
- to remove or control inward or crushing forces, to allow for special load attachments.
Capacity, both of the overall beam and of the individual lift points.
Accessories and attachments – slings, grabs, shackles, hooks etc.
USING LIFTING BEAMS SAFELY
- Lifting beams may incorporate various loose and detachable items of lifting gear. Refer to the separate requirements for the safe use of those items.
- Do not use defective or distorted beams or attachments.
- Lifting beams are generally designed for a specific purpose and should not be used for other purposes without consulting the supplier. This will include the size of crane hook from which they are suspended. On no account should lifting beams be suspended from unsuitable size hooks.
- The weight of the beam, together with its attachments, must be added to the weight of the load when calculating the total load that will be imposed on the crane hook.
- Ensure that the SWL on the individual lift points is not exceeded. Extra care is needed where these are adjustable.
- Ensure the load is stable and that the beam remains at its intended attitude during use. Particular care is needed when lifting and setting down as not only may the load become unstable but individual lift points may become overloaded,
- Use tag lines to control long loads.
- Do not allow the beam to foul the underside of the crane, or any other obstructions, when raising or transporting loads.

When you are out off roading you are prone to getting yourself stuck. Some common scenarios are described below with solutions of how to get yourself out of the jam.
High centred
This happens when something lodges under the vehicle and raises it causing traction to be removed from the wheels. This normally happens on off road tracks that have a high central ridge, crossing logs or where it sinks into sand.
To overcome this one technique is to completely back off. And carefully do it. If you have someone with you get them to lodge an object such as a rock or piece of wood underneath the spinning wheel. Another alternative would be to use a high jack lift which will put good footing underneath allowing you to drive off.
Getting stuck in sand
This often happens when the tyre is not wide enough to spread the actual load of the vehicle and/or the tread is too aggressive. If you’re off roading adventure is a desert crossing then it is advisable to have sand tyres fitted.
If you know your adventure will involve crossing sand then don’t forget to pack a long handled shovel. If you get stuck in sand then first off you need to jack up the wheels by piling sand underneath them and putting floor mats, carpet or whatever you have to hand under the wheels to provide the wheels with some grip. A good tip to know is if you have a pump then deflating air from the tyres so the pressure is reduced will help you get traction. Reduce the weight that is in the vehicle and drive out very very slowly.
