Types of Manohle Lifters
There are several types of manhole lifters available, each designed to accommodate different sizes of manhole covers and to meet specific needs. Here are some common types of manhole lifters:
-
T-Bar Manhole Lifter: This type of lifter features a T-shaped handle with a hook or a clamp at the end. The hook or clamp attaches to the manhole cover, allowing the user to lift it. T-bar lifters are versatile and suitable for various sizes of manhole covers.
-
C-Hook Manhole Lifter: C-hook lifters have a curved hook or clamp that fits around the rim of the manhole cover. The curved design provides a secure grip, making it easier to lift heavy covers.
-
Pole Manhole Lifter: This type of lifter consists of an extendable pole with a hook or mechanism at the end. It's ideal for accessing deeper manholes without the need for workers to bend over or get too close to the opening.
-
Telescopic Manhole Lifter: Similar to the pole lifter, a telescopic lifter allows for adjusting the length of the handle. This type is suitable for reaching manholes at different depths.
-
Hydraulic Manhole Lifter: Hydraulic lifters use hydraulic power to lift and lower manhole covers. They are especially useful for very heavy covers or in situations where manual lifting might be impractical.
-
Mechanical Manhole Lifter: Mechanical lifters use gears and levers to increase the lifting force, making it easier to lift heavy covers. They are suitable for covers that are difficult to lift manually.
-
Magnetic Manhole Lifter: Magnetic lifters use powerful magnets to attach to and lift metal manhole covers. They are especially useful for covers made of materials like cast iron.
-
Vacuum Manhole Lifter: Vacuum lifters create a seal over the manhole cover using suction, allowing the cover to be lifted. They are particularly useful for covers with smooth surfaces.
-
Dual-Purpose Manhole Lifter: Some lifters are designed to serve dual purposes, such as lifting both manhole covers and grates. These versatile tools are commonly used in urban environments with various types of utility access points.
-
Remote-Controlled Manhole Lifter: In certain situations, remote-controlled lifters can be used to lift heavy covers without the need for physical exertion by the operator. These are particularly useful for covers that are difficult to access manually.
