CH-SJG external line high-power high position series lifting mast


Shanghai CanhaoCH-SJGThe high-level innovation series external environmentally friendly lifting mast is a lifting mast device for professional vehicle mounted mobile devices. The mast is fixed on the roof or around the body of the vehicle, vertically lifting equipment such as lighting fixtures, cameras, antennas, etc. to achieve the customer's predetermined function.
The SJG high-level series lifting mast can be selected at different heights of 3.5m-15m according to requirements. If the height within this range cannot meet the work needs of the user, our company can customize a dedicated lifting mast for you according to the user's requirements.
SJG High Position Series Lifting Mast:
(1) Using high-strength aluminum alloy profiles, the inner wall of the cylinder body is treated with high-pressure wear-resistant ceramic technology, and the outer circle of the cylinder body is sandblasted and anodized.
(2) Select high-quality pneumatic components such as one-way valves and pilot operated two position three-way solenoid valves to ensure product quality.
(3) High level sealing performance (imported seals), with a 24-hour lifting mast sliding down less than 10mm in a stationary state.

Technical Instructions for Use

Pin self-locking is a mechanical positioning of each section of the mast based on the structural characteristics of the mast cylinder body model, using the shear force between the full-length foreign key on the outer wall of the cylinder body and the spring pin on the sleeve. The positioning effect depends on the material and cross-sectional area of the key. Due to the aluminum alloy material of the mast cylinder body and the small cross-sectional area of the key, this pin self-locking device is only suitable for small and medium-sized masts with lighter loads.

Direct pull self-locking is generally suitable for masts with an initial height below 1.6m, while diagonal pull self-locking is suitable for masts with an initial height above 1.6m.

The self-locking of the brake is achieved through the frictional force between the brake and the lifting rod, which is equivalent to the wheel and brake device. When using a self-locking mast with a brake, it is necessary to tighten the brake. The required braking force depends on the size of the load, and the tighter the rotation, the greater the braking force. In practical operation, using a torque wrench can clearly determine whether the braking force meets the load requirements. The wrench or torque wrench is an optional accessory, and the calculation method for the self-locking braking force of the brake is to use the formula for tightening torque with threads.

To tighten the torque value, Nm

The F bolt bears clamping force, N；

D thread diameter, mm; P is thread pitch, mm

The integrated brake and the separated brake can achieve the same braking effect, but the difference lies in whether the design can meet the requirements for the initial height, lifting, and load of the mast. Under the same conditions, the initial height of the separated brake mast can be made lower or raised higher.
