Durham Axle CoCommon&quo; Streamline” Open joint planning, with a welding area more than three times that of other traditional pipeline joints, greatly extending the service life and protection life.
It is strictly prohibited to apply excessive pile loads around the foundation pit.
Durham .(5) Each mechanism in the elevator should be checked for normal operation and any noise or other malfunctions. If any, and if any, they should be promptly wrapped or replaced with new ones.
Reasons for the hydraulic boarding bridge lifting platform not lifting: low voltage, motor not rotating, motor reverse, motor phase loss (motor not moving and buzzing), indicator light on press the up button, motor rotates but lifting platform does not rise, lowering valve is open, overflow valve pressure is low, oil level is too low, oil pump is empty, oil suction filter is blocked oil suction section is leaking, and two phases in the three-phase line are arbitrarily changed; Solution: Check the starter potential during motor load operation. Voltage hydraulic range allowed± １０％； Check the motor and circuit; Check the circuit breaker and motor wiring; When the lowering button is released, check the circuit and eliminate the fault; If there is electricity, eliminate the malfunction of the lowering valve itself. The slide valve of the lowering valve must be kept clean and move flexibly. Readjust the overflow valve. Adjust at 100% rated load; Fill up the hydraulic oil; Clean the filter; Check the oil suction pipe and joints; Tighten the joint and replace it if necessary.
.Operation degree: There are two types of operations that can be used to raise and lower the boarding bridge. One is a manual pump station which uses manual hydraulic lifting, which is labor-intensive and somewhat labor-intensive. Advantages: It can be operated and used in any situation. Two types of electric pump stations use electric hydraulic lifting and lowering, which reduces labor intensity and saves labor. Disadvantage: Once the power is cut off, it will not be able to be used, intermediate shafts and bearings, cylinder pins and bearings, boom hinge shafts and bearings, etc; The oil quality and level of hydraulic oil; The hydraulic boarding bridge should be raised throughout the entire process, the hydraulic surface should be 40 to 50 millimeters higher than the bottom of the box. The hydraulic oil is darkened, sticky, or has foreign objects such as gravel. If found, it should be replaced in a timely manner; Add some oil to each part to extend the service life of the bearing. The hydraulic boarding bridge has a wide range of uses. Doing the above points well not only ensures your personal safety but also extends the service life of the equipment, making the boarding bridge better serve you.
conduct.
The reason for the natural descent of the hydraulic boarding bridge lifting platform is that the one-way valve is leaking, the lowering valve is not tightly sealed, and the oil cylinder is leaking. Solution: Check the one-way valve in the valve group. If dirt is found on the sealing surface of a single valve, clean the one-way valve. Check if the lowering valve has power. If there is power, troubleshoot the lowering valve itself or replace the lowering valve. The slide valve of the lowering valve must be kept clean and move flexibly.
Used for cargo platforms and mobile loading and unloading sites without loading and unloading equipment,Durham Lifting and lowering of boarding bridge, it is a cargo loading and unloading auxiliary equipment used in conjunction with forklifts. With the help of hydraulic loading bridges, forklifts can directly enter the interior of car containers for bulk loading and unloading operations. It only needs single person operation and no power supply to realize safe and fast loading and unloading of goods,Durham Aluminum alloy boarding bridge, which can reduce labor intensity, double the efficiency of loading and unloading operations,Durham Fixed hydraulic boarding bridge, speed up the flow of materials, and obtain greater economic benefits.

Free consultation.The precautions during the use of hydraulic boarding bridges are hoped to be helpful to you.
These are the options for hydraulic oil for mobile boarding bridges.
When working in foundation pits or depths, a helmet must be worn.
The precautions during the use of hydraulic boarding bridges are hoped to be helpful to you.
consumption.Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today, I will take you to understand!
Staying below high-altitude work sites is prohibited, and safety nets or other protective devices should be installed below the work site to avoid injury from falling objects.
Install drainage ditches on the ground near the pit of the simple boarding bridge, and take corresponding drainage measures for the top, surface, and foot of the slope, especially for the simple boarding bridge.
Durham .Hydraulic boarding bridges should strictly adhere to the principle of being overweight, as overloading may cause damage to objects; Working on a lifting platform without protective barriers may cause personnel to fall and cause casualties.
To ensure that the hydraulic boarding bridge is in good condition, it should be checked in advance before use, mainly including whether the buttons are effective; Whether the power cord and socket are intact; Whether the oil pipeline is intact; The stability of the guardrail; The tightness of bolts at each junction point; The appearance quality is intact. But when the power is turned on and the indicator light is on, press the up button, the motor rotates but the lifting table does not rise. This may be due to the reverse connection of the three-phase power supply and the motor reversing. Only the power supply needs to be corrected, so it is not a major problem.
Install a 5m high protective railing around the foundation pit of the simple boarding bridge, with a distance of no less than 1m from the protective railing to the foundation pit. The mobile boarding bridge only requires a single person to operate without the need for power supply, and can achieve safe and fast loading and unloading of goods. Mobile boarding bridges are widely used in cargo platforms and mobile loading and unloading sites without loading and unloading equipment. They are auxiliary equipment for cargo loading and unloading that is used in conjunction with forklifts. The sequence of earthwork excavation must comply with design conditions and follow" Trenching support, support first and then excavation, layered excavation, no overbreak&rquote; The principle of.
