1.Main beam

The main beam of a trussed-type electric hoist gantry crane is a critical component that supports the load and provides structural stability to the crane. It is typically designed as a truss, which is a framework of interconnected elements that form a rigid structure. This design offers several advantages, including high strength-to-weight ratio and efficiency in material use.

The trussed main beam usually consists of steel beams arranged in a triangular or other geometric configuration to resist bending and shear forces.The truss design reduces the weight of the crane while maintaining the necessary load-bearing capacity.

The main beam is often constructed from high-strength steel (e.g., Q235, Q345) to provide durability and resistance to heavy loads and environmental conditions.Sometimes, high-tensile steel is used to reduce the weight of the beam while still offering the strength required for heavy-duty applications.

The main beam must be designed to carry the full weight of the crane, as well as any dynamic loads resulting from the operation of the electric hoist.The capacity is influenced by factors such as the length of the span, the crane's lifting capacity, and the type of materials being lifted.

The span of the trussed beam can vary depending on the size of the crane and the area in which it is used (indoor vs outdoor applications).The beam can be a single-span or double-span design depending on the layout and the lifting requirements.The trussed design of the main beam ensures that the structure can withstand torsional and bending forces, especially when the crane is used for heavy lifting or in demanding environments.The stability is also enhanced by the arrangement of the truss elements, which are designed to distribute the weight evenly across the beam.

Lifting System

A lifting system of a trussed type electric hoist gantry crane typically refers to the specific arrangement used for lifting heavy loads using a gantry crane, where the crane itself has a trussed structure to provide strength and stability.

Trussed Type: The gantry crane features a trussed frame, which is a framework of interconnected elements that form a rigid structure. This design is often used in gantry cranes to reduce the amount of material needed, while still providing high strength and stability to support heavy lifting operations.The frame is typically made from steel or other high-strength materials to withstand the heavy loads and stress encountered during operations.The trussed structure may consist of horizontal beams (main girders) and vertical and diagonal braces to form a triangular pattern. This geometry helps distribute the load evenly and reduces the overall weight of the crane compared to a solid frame design.

Hoisting Mechanism: The electric hoist is the primary lifting device, which is mounted on the gantry crane. The hoist includes:

Motor: Provides the power to lift or lower the load.

Drum or Chain: The hoist drum (for wire rope) or chain (for chain hoists) is used to raise and lower the load.

Lift Mechanism: The hoist has a hook or other attachment mechanism for lifting loads. The hook may be movable along the gantry beam.

Electric Drive: The hoist is powered by electricity, with the drive system controlling the movement of the hook along the vertical (lifting/lowering) and horizontal (travel) directions.

3.End carriage

The end carriage of a trussed-type electric hoist gantry crane plays a crucial role in supporting the entire crane structure and enabling it to move along the runway. In the context of a trussed-type design, the end carriage is typically composed of a framework that uses trusses (diagonal and vertical beams) for added strength and reduced weight. This structure is especially beneficial for cranes in industries where lifting heavy loads and working in outdoor environments is common.

The end carriage is made of steel or other high-strength materials, utilizing a truss system that provides excellent load-bearing capacity while maintaining a lightweight frame.The trusses usually have diagonal supports that enhance stability and prevent deflection under heavy loads.Mounted on the end carriage are the wheels that enable the gantry crane to move along the runway (typically rails mounted on the ground).These wheels are usually equipped with bearings and are designed to handle the load and stresses imposed by the crane's motion.

The end carriage must be able to bear the full weight of the hoist and load, distributing it evenly across the crane structure.

Depending on the crane's rated load capacity, the end carriage is designed to handle different weight classes.The electric hoist is often mounted or integrated into the end carriage, or it may be connected via a trolley mechanism. This depends on the crane's design and application.The hoist typically runs along the beam, and its movement is synchronized with the movement of the end carriage.

End carriage helps to maintain alignment and ensures the hoist moves smoothly along the gantry beam. Proper alignment reduces wear on components and extends the crane's service life.Many end carriages are designed with adjustable features to allow for fine-tuning of wheel positions, ensuring proper alignment with the runway rail.The end carriage is built for durability and long service life, often with anti-corrosive coatings or materials for protection against the elements, particularly in outdoor installations.It is also designed to include features such as limit switches to prevent overtravel or other safety mechanisms to protect both the crane and operators.

4.Crane travelling mechanism

1) Operation principle

When the operator activates the travel command, the control system sends a signal to the motor that drives the traveling mechanism. The motor activates the gearboxes, which transmit power to the wheels.As the motor turns the wheels, the crane gantry structure moves along the rail system. The wheels roll along the rails, guided by the fixed track.The speed of the crane's movement is regulated by adjusting the motor speed or controlling the gearbox. The crane can move in both directions (forward and backward) depending on the requirements.The gantry crane's traveling mechanism allows it to move over a large area, positioning the hoist and trolley precisely to lift, transport, and position heavy loads. The hoist moves vertically along the gantry structure, while the trolley (with the load) moves horizontally along the crane's girder.To stop the crane or to hold it in place, the operator can engage the brakes, which are integrated into the system. These electromagnetic brakes are automatically activated to prevent unintended movement.

2) Functional characteristics

The crane traveling mechanism of a trussed-type electric hoist gantry crane plays a crucial role in the movement of the crane along the gantry structure. This mechanism ensures that the crane can move horizontally across the span of the work area, such as a workshop or an outdoor site.

Movement of the Gantry Crane:The traveling mechanism allows the gantry crane to move along its rails or tracks, which are typically installed on the ground or on elevated structures.The crane can move in a longitudinal direction along the rails, covering the entire span of the work area.

Structural Components:The crane traveling mechanism typically has a set of wheels that run along the rails or tracks. These wheels are designed to support the crane's weight and provide smooth motion.The trussed-type gantry crane has a rigid frame made of steel or other high-strength materials. This frame provides structural support and houses the traveling mechanism.The movement of the crane is powered by electric motors driving the wheels. These motors may be located on either side of the crane or integrated into the frame, depending on the design.The rails or tracks provide the path along which the crane moves. Proper alignment and maintenance of the rail system are critical to ensuring smooth and efficient crane operation.

Travel Motors and Controls:The crane is equipped with electric motors that drive the wheels, enabling the crane to move. These motors are typically connected to the wheels through reduction gears.The crane's movement is controlled by an operator via a control panel or remote control. The operator can control the speed and direction of movement (forward or reverse), as well as start/stop the crane. Modern cranes may be equipped with variable frequency drives (VFD) or other electronic control systems that allow for precise control of the crane's travel speed.

5.Trolley travelling mechanism

1) Structural composition

Trolley Frame：The trolley frame is the main structure that supports the hoist and any associated components (like motors, pulleys, etc.). In a trussed-type gantry crane, the trolley frame is designed using a truss structure, which is a lightweight yet strong arrangement of beams. This frame ensures that the hoist can travel along the crane's track while minimizing weight and maximizing strength.

Travel Wheels：The trolley is mounted on a set of travel wheels that run along the rail or beam of the gantry crane. These wheels allow the trolley to move horizontally across the length of the crane.

Electric Motor and Gearbox：The electric motor drives the trolley travel mechanism, providing the necessary power to move the trolley along the crane's beam.

Motor: A three-phase electric motor is commonly used for the trolley traveling mechanism. The motor is mounted on the trolley frame or on a dedicated platform near the frame.

Gearbox: The motor is connected to a gearbox to reduce the motor speed and increase torque, allowing for controlled movement of the trolley. The gearbox typically connects to the travel wheels through a shaft.

Electric or Mechanical Brakes: Electric brakes are often used for precise control, while mechanical brakes may be used for safety in case of power loss.

Rail Installation: The rails are precisely aligned and fixed on the gantry structure to ensure proper travel and minimize wear on the wheels.

2) Functional characteristics

Horizontal Movement (Traveling):The primary function of the trolley traveling mechanism is to provide horizontal movement of the electric hoist along the crane's gantry beam. This movement can be either manual or powered (electric) depending on the design of the crane.It enables the hoist to move the load across the span of the crane to pick up or place materials at different points.

Load Positioning:The trolley mechanism allows for precise load positioning. As the hoist moves along the gantry beam, it helps in accurately aligning the hoist with the load to be lifted or placed.It also ensures the crane can cover the full span of the working area, making it versatile for different lifting tasks.

Smooth and Efficient Operation:The mechanism includes track rollers or wheels, which run on a rail or track system mounted on the crane structure. These are designed to minimize friction and ensure smooth motion during trolley travel.The use of electric motors (often with variable speed control) ensures the trolley can operate at different speeds and stop at precise positions.

Load Distribution and Stability:The trussed design of the crane, combined with the trolley mechanism, helps distribute the load evenly and ensures stability during operation. The trolley is typically designed with robust support structures to prevent any sway or instability when carrying loads.

Safety and Control:The trolley traveling mechanism is equipped with various safety features such as limit switches, brakes, and overload protection. These ensure that the trolley does not travel beyond safe operational limits and that it can stop quickly in case of an emergency.

6.Crane wheel

A crane wheel on a trussed-type electric hoist gantry crane is a crucial component of the crane's mobility system, allowing it to move along the runway or rail system. The design of the wheel and its associated components ensure the crane can bear the load, maintain stability, and operate smoothly.Typically made from high-strength steel, these wheels are designed to withstand heavy loads and resist wear over time.

They are usually cast or forged to achieve the necessary strength and durability.A trussed frame is a structural system that uses a network of beams (or members) connected in a triangular pattern to form a rigid structure. In this type of crane, the wheel assemblies are mounted on the trussed legs, providing a stable base.

The trussed design helps reduce the overall weight of the crane while maintaining strength and stability.

Wheel Design:Crane wheels are designed to be treaded to run along a rail system. The treads of the wheels ensure traction and stability during crane movements.They typically feature grooves to match the rails on which they run.

Load Capacity:

The wheels are designed to handle the dynamic loads exerted by both the crane's dead weight and the additional load it is lifting or carrying.The load-bearing capacity of the wheels should be sufficient for the intended lifting capacity of the crane.

Bearings (often roller or ball bearings) are used in the wheel axle to reduce friction and allow for smooth rotation.Bearings are also designed for high load conditions and to minimize wear during continuous movement of the crane.The axles that connect the wheels to the crane frame are designed to transmit the load from the wheels to the rest of the structure.The housing or casing that contains the axles is reinforced to ensure the crane's stability and minimize any wobbling or misalignment.

The crane wheels are designed to match the specific rail profile that the crane will operate on. Rail profiles vary, so the wheels need to ensure a stable connection with the rail system, ensuring safe movement and load handling.

7.Crane Hook

Main features of hooks

1) Material: Hooks are usually made of high-strength steel to ensure their strength and toughness under high loads. Common materials include carbon steel or alloy steel, which can withstand large tensile and impact forces.

2) Shape design: The shape of the hook is generally "C" or "U" to firmly hang the load while preventing the load from slipping. The depth and width of the hook should be considered during the design to accommodate materials of different shapes and sizes.

3) Safety device: The hook is usually equipped with an anti-unhooking device, such as a safety buckle or locking device, to ensure that the load will not accidentally fall off during the lifting process.

4) Load capacity: The design of the hook needs to take into account the rated lifting weight of the crane, and there will usually be corresponding markings to ensure that its load capacity is not exceeded during use.

Motor

The motor of a trussed type electric hoist gantry crane is a crucial component that drives the hoist mechanism, enabling it to lift and move heavy loads.

Type of Motor:

AC Motors (Alternating Current): These are commonly used in gantry cranes. They can be of the squirrel cage induction type or synchronous motors. They provide reliable performance and are efficient for heavy-duty operations.

DC Motors (Direct Current): These are less common due to maintenance requirements but can provide better speed control, especially for precise operations.

Motor Features:

Explosion-proof: In hazardous environments, motors may need to be explosion-proof or flame-proof, especially if operating in environments where flammable gases or dust may be present.

Brake Motor: A motor with an integrated brake is commonly used to hold the hoist in position once the load has been lifted. This brake prevents the load from falling due to motor stoppage.

Variable Frequency Drive (VFD): A VFD is often used to control motor speed. This allows for smooth acceleration and deceleration, which helps in load control, energy saving, and reducing mechanical stress.
